Abstract
BACKGROUND. Adrenal washout CT is not useful for evaluating incidental adrenal masses in patients without known or suspected primary extraadrenal malignancy. OBJECTIVE. The purpose of our study was to evaluate the diagnostic utility of adrenal mass biopsy in patients without known or suspected extraadrenal primary malignancy. METHODS. This retrospective six-center study included 69 patients (mean age, 56 years; 32 men, 37 women) without known or suspected extraadrenal primary malignancy who underwent image-guided core needle biopsy between January 2004 and June 2021 of a mass suspected to be arising from the adrenal gland. Biopsy results were classified as diagnostic or nondiagnostic. For masses resected after biopsy, histopathologic concordance was assessed between diagnoses from biopsy and resection. Masses were classified as benign or malignant by resection or imaging follow-up, and all nondi-agnostic biopsies were classified as false results. RESULTS. The median mass size was 7.4 cm (range, 1.9-19.2 cm). Adrenal mass biopsy had a diagnostic yield of 64% (44/69; 95% CI, 51-75%). After biopsy, 25 masses were resected, and 44 had imaging follow-up. Of the masses that were resected after diagnostic biopsy, diagnosis was concordant between biopsy and resection in 100% (12/12). Of the 13 masses that were resected after nondiagnostic biopsy, the diagnosis from re-section was benign in eight masses and malignant in five masses. The 44 masses with imaging follow-up included one mass with diagnostic biopsy yielding benign adenoma and two masses with nondiagnostic biopsy results that were classified as malignant by imaging follow-up. Biopsy had overall sensitivity and specificity for malignancy of 73% (22/30) and 54% (21/39), respectively; diagnostic biopsies had sensitivity and specificity for malignancy of 96% (22/23) and 100% (21/21), respectively. Among nine nondi-agnostic biopsies reported as adrenocortical neoplasm, six were classified as malignant by the reference standard (resection showing adrenocortical carcinoma in four, resection showing adrenocortical neoplasm of uncertain malignant potential in one, imaging follow-up consistent with malignancy in one). CONCLUSION. Adrenal mass biopsy had low diagnostic yield, with low sensitivity and low specificity for malignancy. A biopsy result of adrenocortical neoplasm did not reliably differentiate benign and malignant adrenal masses. CLINICAL IMPACT. Biopsy appears to have limited utility for the evaluation of incidental adrenal masses in patients without primary extraadrenal malignancy.

J Am Coll Radiol 2024; 21:107-117. [PMID: 37634790 DOI: 10.1016/j.jacr.2023.04.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 03/24/2023] [Accepted: 04/07/2023] [Indexed: 08/29/2023]
Abstract
BACKGROUND Preferred size-threshold recommendations for management of incidental adrenal lesions remain controversial. PURPOSE This meta-analysis aimed to compare the diagnostic accuracy of different size thresholds for detecting malignancy in patients with incidental adrenal lesions on imaging. MATERIALS AND METHODS A systematic review of MEDLINE, Embase, Scopus, the Cochrane Library, and the gray literature, covering the period from inception to September 2021, was performed. Studies with >10 patients evaluating the diagnostic accuracy of imaging size thresholds for detecting malignancy in patients with incidental adrenal lesions and no prior history of cancer were included. Study, clinical, imaging, and accuracy data for eligible studies were independently acquired by two reviewers. Primary meta-analysis was performed using a bivariate mixed-effects regression model. Risk of bias was evaluated using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. RESULTS From 2,690 citations, 40 studies (9,794 patients with mean age ranging from 41 to 66 years) were included. Most (36 of 40) were retrospective single-center studies. CT with or without MRI served as the index test(s). Sensitivity and specificity values, respectively, by size threshold used in the included studies were as follows: 85% (95% confidence interval [CI] 74%-91%) and 39% (95% CI 23%-57%) for 3-cm thresholds; 85% (95% CI 78%-90%) and 75% (95% CI 62%-85%) for 4-cm thresholds; 70% (95% CI 56%-81%) and 74% (95% CI 59%-85%) for 5-cm thresholds; and 75% (95% CI 67%-82%) and 77% (95% CI 62%-87%) for 6-cm thresholds. No cause for variability in sensitivity or specificity was identified on subgroup analysis of the 4-cm threshold. Nearly half of the studies (19 of 40) had at least one QUADAS-2 domain with a high risk of bias. CONCLUSIONS A 4-cm size threshold demonstrates the highest combined sensitivity and specificity, with a preserved specificity compared with higher size thresholds, but with a trend toward improved sensitivity. Future research reevaluating 4-5 cm size thresholds while excluding characteristically benign lesions by imaging may help redefine a size threshold that has improved specificity but preserved sensitivity, compared with the existing 4-cm threshold.

Abstract
BACKGROUND Incidentally diagnosed adrenal masses represent an entity that can result in either long term follow-up, surgical excision, or both. Understanding when and which adrenal masses are ultimately excised surgically is not well understood. We sought to understand the ultimate fate of these incidentalomas using a large population-based dataset. METHODS The primary outcome of the study was determining the trend in adoption of surveillance vs. surgical excision according to socio-demographic, economic, and pathologic indices, and also provider specialty. Secondary outcomes were the assessment of perioperative complications, operative time, surgical approach, hospital stay, and provider specialty (general surgery vs. urology) among the cohort that underwent excision. RESULTS Out of a total of N.=91,560 adrenal masses, ultimately N.=3375 (3.83%) of these underwent surgical excision. In the surgical excision cohort, the incidence of aldosteronoma, functional adenoma/Cushing's disease, and adrenocortical carcinoma was higher than in the surveillance cohort. Those patients who were older, female, and with higher Charlson Comorbidity indexes (CCI) were less likely to undergo surgical resection. Factors that predicted for an increased probability of resection included obtaining more CT/MRI scans as well as general surgeons as primary physician providers. Over the study period, the vast majority of surgeries were performed by surgeons other than urologists (12.9%) and open and laparoscopic approaches dominated, with the robotic-assisted approach accounting for a minority of the surgical cases (23.9%). The minimally invasive surgery (MIS) approach independently predicted for both lower rates of complications and shorter hospital stay. CONCLUSIONS In the US, adrenal incidentalomas are more likely to undergo surveillance rather than surgical resection. In our study, surgery is mainly offered for functional or malignant disease and the receipt of surgery can vary by physician specialty. A MIS approach independently predicted for both lower rates of complications and shorter hospital stay.

Abstract
Introduction An adrenal incidentaloma (AI) is an unsuspected tumor in one or both adrenal glands, which is discovered incidentally on an imaging exam not prompted by adrenal exploration. The etiologies can be multiple; they condition therapeutic management. The objective of our study is to describe the etiological and therapeutic profiles of AI in our department. Materials and methods A retrospective study was carried out in the Endocrinology, Diabetology, and Nutrition Department of the Hassan II University Hospital of Fez on patients managed for AI from September 2009 until March 2022. We included all the patients who were followed and/or hospitalized for adrenal incidentalomas. Results There were 86, predominantly female, patients (67.85%). The mean age was 58.91+/-14.40 years. The clinical findings were a unilateral adrenal mass in 73.25% of patients, localized on the left in 39.53%, on the right in 33.72%, and a bilateral one in 26.75%. Its size varied from 12 to 196 mm, with an average of 35.5 mm. The most common etiologies found in our series were a non-functional adrenal adenoma in 54.56%, a subclinical cortisolic adenoma in 19.76%, an adrenocortical carcinoma in 5.81%, and a pheochromocytoma in 5.81%. Adrenalectomy was indicated in 19.76% of our patients, 17.44% were monitored closely, 20.94% were monitored for comorbidities, and 41.86% had been advised to abstain from treatment. Conclusion An adrenal incidentaloma has become more and more frequent. It constitutes an entity with various etiologies, which can be serious. The main etiology in our series was non-functioning adrenal adenoma, for which therapeutic abstention was indicated in 48% of cases.

Abstract
PURPOSE To evaluate differences between patients with unilateral and bilateral adrenal incidentalomas (AIs) in the prevalence of autonomous cortisol secretion (ACS) and related comorbidities. METHODS In this multicentre retrospective study, AIs ≥ 1 cm without overt hormonal excess were included in the study. ACS was defined by a post-dexamethasone suppression test (DST) serum cortisol ≥ 5.0 µg/dl, in the absence of signs of hypercortisolism. For the association of ACS with the prevalence of comorbidities, post-DST serum cortisol was also analysed as a continuous variable. RESULTS Inclusion criteria were met by 823 patients, 66.3% had unilateral and 33.7% bilateral AIs. ACS was demonstrated in 5.7% of patients. No differences in the prevalence of ACS and related comorbidities were found between bilateral and unilateral AIs (P > 0.05). However, we found that tumour size was a good predictor of ACS (OR = 1.1 for each mm, P < 0.001), and the cut-off of 25 mm presented a good diagnostic accuracy to predict ACS (sensitivity of 69.4%, specificity of 74.1%). During a median follow-up time of 31.2 (IQR = 14.4-56.5) months, the risk of developing dyslipidaemia was increased in bilateral compared with unilateral AIs (HR = 1.8, 95% CI = 1.1-3.0 but, this association depended on the tumour size observed at the end of follow-up (HR adjusted by last visit-tumour size = 0.9, 95% CI = 0.1-16.2). CONCLUSIONS Tumour size, not bilaterality, is associated with a higher prevalence of ACS. During follow-up, neither tumour size nor bilaterality were associated with the development of new comorbidities, yet a larger tumour size after follow-up explained the association of bilateral AIs with the risk of dyslipidaemia.

Computed tomography (CT) scan identified necrosis, but is it a reliable single parameter for discerning between malignant and benign adrenocortical tumors? Surgery 2021; 171:104-110. [PMID: 34183180 DOI: 10.1016/j.surg.2021.04.042] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Revised: 03/20/2021] [Accepted: 04/05/2021] [Indexed: 12/17/2022]
Abstract
BACKGROUND Adrenocortical carcinoma is a rare malignant tumor with a poor prognosis. Discernment of adrenocortical carcinoma in an adrenal mass through imaging studies is paramount for early surgical treatment. Recently, necrosis has been proposed as a single morphological parameter for adrenocortical carcinoma diagnosis. The aim of this study was to analyze the measures of diagnostic efficiency of necrosis and the different computed tomography-scan features related to adrenocortical carcinoma diagnosis. METHODS We conducted a case-control study of patients surgically treated for an adrenal mass with histopathological report consistent with adrenocortical carcinoma (cases) and adrenocortical adenoma (control patients) between 1987 and 2019. Radiological features on computed tomography scan were collected. Bivariate and multivariate statistical analyses were performed for the different imaging features. The measures of diagnostic efficiency for each feature were calculated. Concordance analysis between image-detected and histopathological-identified necrosis was performed. RESULTS Eighteen adrenocortical carcinoma and 41 adrenocortical adenomas were included. Differences between adrenocortical carcinoma and adrenocortical adenoma were found regarding heterogeneity (odds ratio 4.53, 95% confidence interval 2.3-8.9; P < .0001), tumor size ≥4 cm (odds ratio 3.5, 95% confidence interval 2.05-6.14; P < .0001), and attenuation index ≥10 Hounsfield units (odds ratio 1.9, 95% confidence interval 1.3-2.6; P = .001). Necrosis was the most important imaging feature significantly associated with adrenocortical carcinoma (odds ratio 35, 95% confidence interval 5.1-241.6; P < .0001), present in all adrenocortical carcinoma cases. After measures of diagnostic efficiency calculation, necrosis had the highest diagnostic accuracy (98%). Cohen's kappa for concordance between image-detected and histopathological-identified necrosis was 90.4% (P < .0001). CONCLUSION Computed tomography scan-detected necrosis is a reliable radiological feature to discern adrenocortical carcinoma from adrenocortical adenomas.

Abstract
An adrenal incidentaloma is now established as a common endocrine diagnosis that requires a multidisciplinary approach for effective management. The majority of patients can be reassured and discharged, but a personalized approach based upon image analysis, endocrine workup, and clinical symptoms and signs are required in every case. Adrenocortical carcinoma remains a real concern but is restricted to <2% of all cases. Functional adrenal incidentaloma lesions are commoner (but still probably <10% of total) and the greatest challenge remains the diagnosis and optimum management of autonomous cortisol secretion. Modern-day surgery has improved outcomes and novel radiological and urinary biomarkers will improve early detection and patient stratification in future years to come.

Practical guide on the initial evaluation, follow-up, and treatment of adrenal incidentalomas Adrenal Diseases Group of the Spanish Society of Endocrinology and Nutrition. ACTA ACUST UNITED AC 2020; 67:408-419. [PMID: 32349941 DOI: 10.1016/j.endinu.2020.03.002] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Accepted: 03/03/2020] [Indexed: 12/16/2022]
Abstract
Initial evaluation of adrenal incidentalomas should be aimed at ruling out malignancy and functionality. For this, a detailed clinical history should be taken, and an adequate radiographic assessment and a complete blood chemistry and hormone study should be performed. The most controversial condition, because of the lack of consensus in its definition, is autonomous cortisol secretion. Our recommendation is that, except when cortisol levels <1.8μg/dL in the dexamethasone suppression test rule out diagnosis and levels ≥5μg/dL establish the presence of autonomous cortisol secretion, diagnosis should be based on a combined definition of dexamethasone suppression test ≥3μg/dL and at least one of the following: elevated urinary free cortisol, ACTH level <10 pg/mL, or elevated nocturnal cortisol (in serum and/or saliva). During follow-up, dexamethasone suppression test should be repeated, usually every year, on an individual basis depending on the results of prior tests and the presence of comorbidities potentially related to hypercortisolism. The initial radiographic test of choice for characterization of adrenal incidentalomas is a computed tomography scan without contrast, but there is no unanimous agreement on subsequent monitoring. Our general recommendation is a repeat imaging test 6-12 months after diagnosis (based on the radiographic characteristics of the lesion). If the lesion remains stable and there are no indeterminate characteristics, no additional radiographic studies would be needed. We think that patients with autonomous cortisol secretion with comorbidities potentially related to hypercortisolism, particularly if they are young and there is a poor control, may benefit from unilateral adrenalectomy. The indication for unilateral adrenalectomy is clear in patients with overt hormonal syndromes or suspected malignancy. In conclusion, adrenal incidentalomas require a comprehensive evaluation that takes into account the possible clinical signs and comorbidities related to hormonal syndromes or malignancy; a complete hormone profile (taking into account the conditions that may lead to falsely positive and negative results); and an adequate radiographic study. Monitoring and/or treatment will be decided based on the results of the initial evaluation.

Abstract
Introduction Adrenal incidentalomas (AI) are adrenal masses that are discovered during radiological examinations conducted for other reasons. In this study, we focused on the pathological and radiological properties of nonfunctional AI(NFAI) and the association with malignancy risk in our clinical series. Methods A total of 186 patients underwent adrenalectomy between 2010 and 2017; of these, 76 (40.8%) patients with non-functional AI were included in the current study. The radiological and pathologic characteristics of these AIs were retrospectively analyzed to determine the malignancy rate. Results There were 22 (28.9%) male and 54 (71.1%) female patients with nonfunctional AI included in this study. The median age was 55 (range: 24-85) years. Of the patients included, 37 (48.6%) had AI on the left and 39 (51.3%) had AI on the right adrenal gland. Sixty-one (80.2%) cases were treated laparoscopically, four (5.3%) required conversion to open surgery due to intraoperative difficulties such as bleeding and adhesions, and 11 (14.4%) were managed with open adrenalectomy. The rate of malignancy in the tumors with diameters of <4 cm, 4-6 cm, and >6 cm was found to be 0%, 2.9%, and 13.6%, respectively. Conclusions Determining the ideal cutoff value for surgical indication in an NFAI is challenging. Besides the malignancy risk, the rate of silent pheochromacytomas must be taken into account in the surgical decision.

Abstract
Adrenal incidentalomas (AI) are one of the most frequent reasons for consultation in Endocrinology, as they are present in 3-10% of the general population. Up to 20% of them may have autonomous cortisol secretion (ACS), a term that refers to AI carriers with biochemical evidence of excess cortisol, but without the "specific" clinical signs of Cushing's syndrome. As ACS is associated with an increased risk of diabetes, obesity, high blood pressure (HBP), osteoporosis, cardiovascular events, and global mortality; its correct identification is of great importance. There are different laboratory assays to detect ACS, but all of them have some limitations. The dexamethasone suppression test is the most accepted for screening. However, there is no consensus on the cutoff point that should be used. Low levels of ACTH and DHEA-S and high urinary free cortisol are also associated with ACS, but in isolation they are of little value to establish the diagnosis. Considering its clinical implications and the lack of consensus in the diagnosis and in which is the most appropriate management of these patients, this review offers a quick reference guide of ACS, presenting an exhaustive review of the topic: its definition, epidemiology, diagnosis, clinical implications, treatment, and follow-up.

Abstract
Aims and background The incidental finding of nonfunctioning adrenal masses (incidentalomas) is common, but no reliable criteria in differentiating between benign and malignant adrenal masses have been defined. The aim of this preliminary study was to assess the usefulness of adrenal imaging and image-guided fine-needle aspiration cytology in patients with nonfunctioning adrenal incidentalomas with the aim of excluding or confirming malignancy before surgery. Methods Forty-two consecutive patients (18 men and 24 women; median age, 54 years; range, 25-75 years) with incidentally discovered adrenal masses of 3 cm or more in the greatest diameter were prospectively enrolled in the study. All patients underwent helical computerized tomography scan and image-guided fine-needle aspiration cytology, 33 (78.6%) underwent magnetic resonance imaging, and 26 (61.9%) underwent norcholesterol scintigraphy before adrenalectomy. Results The revised final pathology showed 30 (71.4%) benign (26 adrenocortical adenomas, of which 3 were atypical, 2 ganglioneuromas, and 2 nonfunctioning benign pheochromocytomas) and 12 (28.6%, 95% CI = 15-42) adrenal malignancies (8 adrenocortical carcinomas and 4 unsuspected adrenal metastases). The definitive diagnosis of adrenocortical carcinoma was made according to Weiss criteria and confirmed on the basis of local invasion at surgery or metastases. The sensitivity, specificity and accuracy were 75%, 67% and 83% for computerized tomography scan, 92%, 95% and 94% for magnetic resonance imaging, 89%, 94% and 92% for norcholesterol scintigraphy, and 92%, 100% and 98% for fine-needle aspiration cytology. The sensitivity and accuracy of image-guided fine-needle aspiration cytology and magnetic resonance imaging together reached 100%. Immediate periprocedural complications of fine-needle aspiration cytology occurred in 2 (4.7%) patients: self-limited pneumothorax (n = 1), and severe pain (n = 1) requiring analgesic therapy. No postprocedural or late complications were observed. Conclusions With the aim of selecting for surgery patients with a non-functioning adrenal incidentaloma of 3 cm or more in diameter, the combination of magnetic resonance imaging and fine-needle aspiration cytology should be considered the strategy of choice.

Abstract
Adrenal incidentalomas are unsuspected, asymptomatic adrenal masses detected on imaging. Most are non-functioning benign adrenocortical adenomas but can represent other benign lesions or lesions requiring therapeutic intervention including adrenocortical carcinoma, pheochromocytoma, hormone-producing adenoma or metastasis. This review summarizes and highlights radiological recommendations within the recently issued guidelines for the management of adrenal incidentalomas from the European Society of Endocrinology Clinical Practice in collaboration with the European Network for Study of Adrenal Tumours. Four pre-defined clinical questions were addressed in the guidelines and two have specific relevance and implications for radiologists: (1) how to assess risk of malignancy on imaging and (2) what follow-up is indicated if an adrenal incidentaloma is not surgically removed? The guidelines also include recommendations for frequently encountered special circumstances, including bilateral incidentalomas, incidentalomas in patients with extra-adrenal malignancy and in the young and elderly patients. This review highlights radiological recommendations within the guidelines and evidence used for formulating the guidelines.

Abstract
An adrenal mass can be either symptomatic or asymptomatic in the form of adrenal incidentalomas (AIs) in up to 8 % in autopsy and 4 % in imaging series. Once a diagnosis of adrenal mass is made, we need to differentiate whether it is functioning or nonfunctioning, benign, or malignant. In this article, we provide a literature review of the diagnostic workup including biochemical evaluation and imaging characteristics of the different pathologies. We also discuss the surgical strategies with laparoscopy as the mainstay with partial adrenalectomy in select cases and adrenalectomy in large masses. Follow-up protocol of AIs and adrenocortical carcinoma is also discussed.

Abstract
Due to the increasing use of radiological investigations, the detection of incidental adrenal masses has become even more frequent. Therefore, it is crucial to identify the nature of the adrenal mass in order to decide the type of treatment that should be undertaken. Toward this goal, biochemical tests are useful in order to assess catecholamines levels for the presence of a pheochromocytoma or cortisol excess in case of Cushing's syndrome. Furthermore, the dexamethasone suppression test and late-night salivary cortisol may be useful in measuring plasma cortisol, respectively, in the blood and urine. Hyperaldosteronism could be suspected in the presence of arterial hypertension. With regard to imaging modalities, the contrast washout and Hounsfield units estimation might play a role as indicators on computed tomography. In terms of treatment, a surgical approach is most suitable for a hyperfunctioning adrenal mass irrespective of size, and for nonfunctioning masses >4 cm. For indeterminate smaller lesions, with washout >50%, <10 Hounsfield Unit, nonfunctioning, benign-appearing, undergoing a follow-up in regular intervals is more appropriate in order to estimate mass growth. This paper summarizes recent findings on the management of incidental adrenal masses, with a special focus on the use of imaging, surgical management and follow-up modalities in improving patient outcomes.

Abstract
: By definition, an adrenal incidentaloma is an asymptomatic adrenal mass detected on imaging not performed for suspected adrenal disease. In most cases, adrenal incidentalomas are nonfunctioning adrenocortical adenomas, but may also represent conditions requiring therapeutic intervention (e.g. adrenocortical carcinoma, pheochromocytoma, hormone-producing adenoma or metastasis). The purpose of this guideline is to provide clinicians with best possible evidence-based recommendations for clinical management of patients with adrenal incidentalomas based on the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. We predefined four main clinical questions crucial for the management of adrenal incidentaloma patients, addressing these four with systematic literature searches: (A) How to assess risk of malignancy?; (B) How to define and manage low-level autonomous cortisol secretion, formerly called 'subclinical' Cushing's syndrome?; (C) Who should have surgical treatment and how should it be performed?; (D) What follow-up is indicated if the adrenal incidentaloma is not surgically removed? SELECTED RECOMMENDATIONS: (i) At the time of initial detection of an adrenal mass establishing whether the mass is benign or malignant is an important aim to avoid cumbersome and expensive follow-up imaging in those with benign disease. (ii) To exclude cortisol excess, a 1mg overnight dexamethasone suppression test should be performed (applying a cut-off value of serum cortisol ≤50nmol/L (1.8µg/dL)). (iii) For patients without clinical signs of overt Cushing's syndrome but serum cortisol levels post 1mg dexamethasone >138nmol/L (>5µg/dL), we propose the term 'autonomous cortisol secretion'. (iv) All patients with '(possible) autonomous cortisol' secretion should be screened for hypertension and type 2 diabetes mellitus, to ensure these are appropriately treated. (v) Surgical treatment should be considered in an individualized approach in patients with 'autonomous cortisol secretion' who also have comorbidities that are potentially related to cortisol excess. (vi) In principle, the appropriateness of surgical intervention should be guided by the likelihood of malignancy, the presence and degree of hormone excess, age, general health and patient preference. (vii) Surgery is not usually indicated in patients with an asymptomatic, nonfunctioning unilateral adrenal mass and obvious benign features on imaging studies. We provide guidance on which surgical approach should be considered for adrenal masses with radiological findings suspicious of malignancy. Furthermore, we offer recommendations for the follow-up of patients with adrenal incidentaloma who do not undergo adrenal surgery, for those with bilateral incidentalomas, for patients with extra-adrenal malignancy and adrenal masses and for young and elderly patients with adrenal incidentalomas.

Abstract
Adrenal incidentalomas are adrenal masses discovered incidental to imaging studies performed for reasons unrelated to adrenal pathology. Although most adrenal incidentalomas are non-functioning benign adenomas, their increasing prevalence presents diagnostic and therapeutic challenges. The assessment of adrenal incidentalomas is aimed at deciding whether or not the tumour should be surgically removed. Adrenalectomy is indicated for phaeochromocytoma, other symptomatic hormone-secreting tumours and those with a high risk of malignancy. Biochemical screening for tumour hypersecretion is mandatory in all adrenal incidentalomas, since hormone secreting tumours may be clinically silent. The diagnosis of phaeochromocytoma is of paramount importance because of its life-threatening complications. Non-functioning adrenal incidentalomas need assessment for risk of malignancy, and this is based on the size of the tumour and its imaging characteristics. An observational policy with periodic radiological and biochemical reassessment is pursued in patients with non-functioning incidentalomas with low malignancy risk. The duration and frequency of reassessment remains unclear, as the natural history of adrenal incidentalomas has yet to be clearly defined, and there is a lack of controlled studies comparing surgical intervention with observation. However, the possibility of acquiring autonomous hypersecretion or conversion to malignancy in an incidentaloma diagnosed to be a benign non-functioning lesion is very low, and most patients may be safely discharged after an initial follow-up period of 2 years.

Abstract
Pheochromocytomas or functioning paragangliomas can present in a dramatic manner with headache, palpitations and sometimes shock, but many occur with few symptoms despite at times markedly elevated catecholamine levels. Hypertension is not invariable, and may be paroxysmal. Increased diligence in the diagnosis of presymptomatic pheochromocytoma/paraganglioma is warranted from autopsy studies, suggesting that many of these tumors may be fatal at first presentation. Fortunately, an increasing number of pheochromocytomas/paragangliomas are now diagnosed before the advent of symptoms, either as an incidental finding on abdominal imaging or by targeted surveillance in subjects with known genetic susceptibility. The challenges and pitfalls associated with diagnosis of these silent pheochromocytoma/paragangliomas are reviewed in this article.

Abstract
The routine use of abdominal procedure has significantly increased the incidental finding of adrenal masses. The prevalence of these tumors, commonly defined as adrenal incidentalomas, ranges between 2-3% in autopsy and 4% in radiological series, reaching 5-8% in oncological studies and increasing with patients age. Although clinically silent, in 5-20% of cases, adrenal incidentalomas are responsible for a subtle cortisol overproduction, commonly defined as "subclinical Cushing's syndrome" (SCS). This term is used to describe autonomous cortisol secretion in patients who don't have the typical signs and symptoms of hypercortisolism. The optimal strategy for identification and management of SCS is unknown; the standard biochemical tests used to screen for overt Cushing's syndrome are generally ill-suited to the assessment of patients who have no, or only very mild signs of cortisol excess, then many tests aimed to study the hypothalamus-pituitary-adrenal axis (HPA) axis do not have sufficient sensitivity to recognize very mild degree of cortisol excess. An increased frequency of hypertension, central obesity, impaired glucose tolerance or diabetes, hyperlipemia and osteoporosis has been described in patients with SCS since patients are exposed to a chronic albeit slight, cortisol excess; however, there is not evidence-based demonstration of long term complications and, consequently, the management of this condition is largely empirical. Adrenalectomy or medical management of associated disease has been indicated as therapeutic options due to lack of data demonstrating the superiority of a surgical or non-surgical treatment.

Abstract
Pyogenic granuloma (PG) is a tumor-like lesion that typically arises on human skin. Intravenous pyogenic granuloma (IVPG) is the vascular counterpart, mostly observed in the venous structures of the neck and upper extremities. Chronic irritation of the skin, traumatic injury, and hormonal alterations seem to be implicated in the pathogenesis of PG. The incidence of PG, and IVPG, is very low in the reported scientific literature, and this underlines the need for understanding unresolved questions concerning the uncommon presentation, and correct diagnosis before surgical intervention. This report describes a case of IVPG diagnosed in a 55-year-old female that presented for observation of chronic abdominal pain associated with nausea and anorexia. A well-defined mass located in the right adrenal gland was documented by ultrasonography and finally confirmed by contrast enhanced CT of the abdomen. There were no radiological signs of liver, kidney, or vascular infiltration. The 35 × 22 mm adrenal gland lesion, suspected to be an adrenal gland tumor, was resected using a minimally invasive approach. Laparoscopic right adrenalectomy was successfully performed. The histology documented the typical morphological features of IVPG in the context of a normal right adrenal gland. This report describes and discusses the unusual presentation of intraabdominal IVPG located in the adrenal gland region together with a review of the current literature.

Abstract
BACKGROUND Fine-needle aspiration (FNA) of adrenal masses is a method currently indicated in lesions suspected of being extra-adrenal in origin; even though its diagnostic reliability has already been determined in many studies, few have used histological examination obtained after adrenalectomy for diagnostic confirmation. AIM To analyze the diagnostic performance of adrenal FNA in subjects with an available histological confirmation. SUBJECTS AND METHODS Fifty subjects (26 benign adrenal lesions, 9 primary malignant lesions, and 15 metastatic lesions) who had undergone ultrasound (US)-guided adrenal FNA and then adrenalectomy were re-analyzed retrospectively. RESULTS FNA guaranteed a sensitivity of 85.7% and a specificity of 100% in all subjects; after having divided the subjects into oncologic and non-oncologic groups, the sensitivity of the test in oncologic patients (100%) increased significantly compared to non-oncologic (57.1%) with no difference in specificity (100% in both groups). Considering also non-diagnostic samples in our analysis (no.=11; 22% of all samples studied), FNA correctly diagnosed malignancy only in 75% of the cases and benignancy only in 66.6%; however, even after including non-diagnostic samples, the percentage of correct malignancy diagnosis remained significantly higher in oncologic (93.3%) than in non-oncologic patients (44.4%) without significant statistical difference between the 2 groups regarding the percentage of correct benignancy diagnosis (respectively 100% and 63.6%). CONCLUSIONS Our study, based on histological confirmation, underlines the low discriminant value of US-guided adrenal FNA, though the method may have value in oncologic patients.

Abstract
BACKGROUND The term adrenal incidentaloma (AI) indicates an adrenal mass lesion > 1 cm in diameter discovered during testing for conditions unrelated to adrenal disease. The overall prevalence of these lesions ranges between 3% and 10%. Their incidence increases with age, and it is clinically important to identify AI associated with hormonal activity and/or malignant potential. DESIGN A detailed Medline search of all English language articles related to AI was carried out, and the clinical implications related to their hormonal activity and malignant potential are discussed. RESULTS The subclinical hypercortisolism observed in a significant percentage of patients with AI is associated with some of the detrimental effects of continuous autonomous cortisol secretion, including a higher prevalence of hypertension, dyslipidaemia, impaired glucose tolerance or type 2 diabetes mellitus and an increased risk for osteoporotic fractures. However, it remains to be proven whether treatment to reverse subtle glucocorticoid excess is beneficial. Clinically silent phaeochromocytomas and primary adrenal cancer are conditions associated with significantly high morbidity and mortality and require urgent treatment, while the prevalence and clinical significance of autonomous mineralocorticoid secretion are less clearly defined. Size and radiological features are the main predictors of malignant potential. CONCLUSIONS Patients harbouring AI should be evaluated for the possibility of malignancy and/or subclinical hypercortisolism which is associated with cardiovascular risk and bone loss. However, in the absence of prospective controlled studies correlating biochemical activity with end-organ complications, the long-term consequences of AI remain uncertain and their management remains largely pragmatic.

Abstract
CONTEXT Subclinical hypercortisolism (SH) is a condition of biochemical cortisol excess without the classical signs or symptoms of overt hypercortisolism. It is thought to be present in the 5-30% of patients with incidentally discovered adrenal mass (adrenal incidentalomas), which in turn are found in 4-7% of the adult population. Therefore, SH has been suggested to be present in 0.2-2.0% of the adult population. Some studies suggested that this condition is present in 1-10% of patients with diabetes or established osteoporosis. The present manuscript reviews the literature on diagnostic procedures and the metabolic effect of the recovery from SH. EVIDENCE ACQUISITION A PubMed search was used to identify the available studies. The most relevant studies from 1992 to November 2010 have been included in the review. EVIDENCE SYNTHESIS The available data suggest that SH may be associated with chronic complications, such as hypertension, diabetes mellitus, overweight/obesity, and osteoporosis. The available intervention studies suggest that the recovery from SH may lead to the improvement of hypertension and diabetes mellitus. A retrospective study suggests that this beneficial effect could be predicted before surgery. CONCLUSIONS SH is suggested to be associated with some chronic complications of overt cortisol excess. Recovery from this condition seems to improve these complications. However, a large, prospective, randomized study is needed to confirm this hypothesis and to establish the best diagnostic approach to identify patients with adrenal incidentalomas who can benefit from surgery.

Abstract
Histoplasmosis is a fungal disease endemic in central and eastern states of United States, South America, Africa, and Asia. It may present as chronic pulmonary infection or in disseminated form of infection. The disseminated form of histoplasmosis frequently affects the adrenal gland and is more likely to affect immunocompromised patients as compared to immunocompetent individuals. There are very few cases of adrenal histoplasmosis diagnosed on fine needle aspiration cytology. In the present era when fine needle aspiration has become popular modality for diagnosis, adrenal fine needle aspiration is still a less commonly practiced technique. We report eight cases of adrenal histoplasmosis diagnosed on fine needle aspiration cytology in patients with bilateral adrenal masses. The present case series supports the role of fine needle aspiration cytology of adrenal gland infections where surgery can be prevented and a definitive diagnosis can be made on which treatment can be offered.

Abstract
OBJECTIVE The aim of this study was to investigate the possible urinary markers of hormonal activity in patients with non-functioning adrenal incidentalomas. In order to evaluate the endocrine activity of aforementioned tumours, urinary steroid metabolite levels were analyzed in samples from patients and controls. Possible blocks in metabolic pathways of the examined hormones were determined by comparing selected urinary steroid metabolite sums and ratios in both groups of interest. DESIGN Urine samples were collected from 20 patients with non-functioning adrenal incidentalomas and from 25 controls matched in terms of age, sex and BMI. Excretion of 19 major urinary steroid metabolites was analyzed by gas chromatography. The results were subjected to statistical analysis. RESULTS In patients with adrenal incidentalomas sum of total urinary cortisol metabolites was significantly increased in respect to the control group. We also observed a shift towards tetrahydrocorticosterone, cortisol and etiocholanolone production in patients. No significant differences in production of other urinary steroid metabolites were noted in patients with adrenal incidentalomas in respect to control group. CONCLUSIONS Our data suggests that not only urinary free cortisol but also its metabolite such as tetrahydrocortisol and other steroids including etiocholanolone and corticosterone tetrahydrometabolite might be urinary markers for the endocrine activity of adrenal incidentalomas. Enhanced levels of these urinary steroid metabolites indicate an impairment of 11beta-hydroxysteroid dehydrogenase activity and slightly increased activity of 5beta-reductase in patients with adrenal incidentalomas.

Abstract
BACKGROUND In a patient with a history of cancer, an isolated adrenal mass is usually thought to be a metastasis. Although a biochemical work-up to rule out pheochromocytoma is recommended, some question its practicality. This study was undertaken to determine the incidence of functional adrenal lesions in patients with a history of cancer and examine predictive factors for the type of lesion. METHODS At a single institution, 33 patients with an isolated adrenal mass and a history of cancer underwent surgical treatment. Patients' records were retrospectively analyzed for type of adrenal lesion and other diagnostic parameters. RESULTS There were 20 males and 13 females with a mean age of 58+/-2 years. Of these, 20 (61%) had adrenal metastases, 8 (24%) had pheochromocytomas, and 5 (15%) had adrenal adenomas. Usual diagnostic criteria, including presenting symptoms, primary tumor, and other demographic characteristics, did not consistently predict the pathology of the lesion. CONCLUSIONS Nearly 1 in 4 resected adrenal masses in patients with a history of cancer were pheochromocytomas. The high incidence of pheochromocytoma in this series supports a thorough work-up, irrespective of previous cancer. Therefore, remember one thing in patients with an isolated adrenal mass and a history of cancer: pheochromocytoma.

Abstract
INTRODUCTION The accidental discovery of an adrenal mass called incidentaloma has become an increasingly frequent clinical problem with the question of a correct and appropriate therapeutic approach being the subject of controversial discussions. MATERIALS AND METHODS Clinical charts of 52 patients (22 male, 30 female) who underwent adrenalectomy for an incidentaloma at our institution between 1987 and 2001 were reviewed. RESULTS Median age was 56.4 years. Reasons for surgery were unclear significance in 22 patients, suspicion of malignancy in 5, increase in size in 8, maximum tumor diameter of more than 5 cm in 7, fear of malignancy in 1, and subclinical secretion of cortisol in 5 patients. No data were available for 4 patients. Surgical resection was performed using a conventional transabdominal approach in 28 patients, a conventional dorsal approach in 17 patients, and an endoscopic retroperitoneal approach in 7 patients. Histopathologic examination ruled out adrenal adenoma in 32 patients, adrenal myelolipoma in 12, unilateral nodular hyperplasia in 4, cystic lesion in 3, and adrenocortical carcinoma in 1 patient. The mean size of all lesions was 5.5 cm. Evaluating the criteria for surgical treatment regarding age of the patients and size of the lesions, 25 patients (48%), including the patient with the adrenocortical carcinoma, were younger than 60 years and had an adrenal lesion exceeding 4 cm in size. During postoperative follow-up that was available for 39 patients, 3 developed contralateral tumors that were treated by resection in 1 and by close follow-up in 2. CONCLUSIONS Size should not be the sole criterion; treatment should be tailored to the individual patient. Especially in patients younger than 60 years with an adrenal lesion exceeding 4 cm in size, an adrenalectomy, predominantly via an endoscopic approach, should be carried out, because a repeated and life-long close follow-up of an anxious patient who has been informed of the diagnosis will in some cases exceed the cost of a single endoscopic operation.

Abstract
Subclinical hypercortisolism (SH) is a newly characterized hormonal disorder that is almost exclusively detected in the context of incidentally discovered adrenal masses. The diagnostic criteria used for the definition of this condition are at present controversial. Amongst the various tests used for the detection of this abnormality (dexamethasone suppression, urinary free cortisol, ACTH levels, midnight serum or salivary cortisol concentrations, ACTH responses to CRH stimulation), the dexamethasone suppression tests (DST) seem to better accomplish the task of unmasking subtle abnormalities of cortisol secretion. Several versions of DST have been used: the 1-mg overnight, the 3-mg overnight and the classical 2-day low-dose DST. This latter test has the theoretical advantage that, by more efficiently suppressing pituitary ACTH secretion, it may provide a measure of the residual (ie non- ACTH-dependent) cortisol secretion from the adrenal mass. In this way, post-dexamethasone cortisol concentrations may quantify the degree of autonomous cortisol hypersecretion. In fact, post-dexamethasone cortisol concentrations have a negative correlation with basal ACTH levels and a positive correlation with midnight cortisol concentrations as well as the size of the incidentally discovered adrenal mass. Most of the existing data indicate that SH detected in the context of adrenal incidentalomas may have some clinically significant implications. In fact, patients with higher post-dexamethasone cortisol concentrations demonstrate higher lipid levels and lower bone mass densities. It has also been suggested that SH may be responsible for biochemical and phenotypic changes reminiscent of the metabolic syndrome. In summary, SH does exist and is associated with a negative impact in patients' health; however, hormonal cut-off criteria for decision-making remain to be defined.

Abstract
Adrenal incidentalomas, defined as masses discovered incidentally during imaging investigation of non-adrenal disorders, have become a rather common finding in clinical practice. The prevalence is not well characterized and varies among studies. The aim of the present study was to perform a prospective evaluation of the prevalence of adrenal incidentalomas among subjects undergoing computerized tomography (CT) scan of the chest in a screening program of lung cancer (Tic TAC study) in Piedmont, a region of Northwestern Italy. This evaluation included 520 subjects (382 males and 138 females, aged between 55-82 yr), referred to our hospital from April to December 2001. Twenty-three patients with adrenal masses were identified: 21 adrenal adenomas, 1 myelolipoma, and 1 metastasis of lung cancer. Therefore, the overall prevalence of adrenal lesions was 4.4%, and that of benign adrenal masses was 4.2%. This prevalence is higher than those found in previous CT scan series reported in the literature, probably because of the use of high-resolution CT scanning technology. Another factor that influenced our results is that subject age is skewed towards the decades characterized by a greater occurrence of adrenal masses. The outcome of this study confirms that we are presently able to identify incidentally discovered adrenal masses more often than in early years and that the prevalence of adrenal incidentalomas on CT images is approaching that of autopsy series. The present study provides a reliable estimate of the prevalence of adrenal incidentaloma with currently used CT scanners. Notwithstanding that our subjects were at increased risk of lung cancer, the rate of adrenal metastases was low. We think that the present results can be generalized even if we may disclose the lack of histological diagnosis.

Abstract
OBJECTIVES To examine the risk of developing adrenal carcinomas and clinically overt hypersecreting tumours during short-term follow-up in patients with adrenal incidentalomas. DESIGN 229 (98 males and 131 females) patients with adrenal incidentalomas were investigated in a prospective follow-up study (median time 25 months; range 3-108 months). The patients were registered between January 1996 and July 2001 and followed until December 2004. Twenty-seven Swedish hospitals contributed with follow-up results. METHODS Diagnostic procedures were undertaken according to a protocol including reinvestigation with computed tomography scans after 3-6 months, 15-18 months and 27-30 months, as well as hormonal evaluation at baseline and after 27-30 months of follow-up. Operation was recommended when the incidentaloma size increased or if there was a suspicion of a hypersecreting tumour. RESULTS The median age at diagnosis of the 229 patients included in the follow-up study was 64 years (range 28-84 years) and the median size of the adrenal incidentalomas when discovered was 2.5 cm (range 1-8 cm). During the follow-up period, an increase in incidentaloma size of > or =0.5 cm was reported in 17 (7.4%) and of > or =1.0 cm was reported in 12 (5.2%) of the 229 patients. A decrease in size was seen in 12 patients (5.2%). A hypersecreting tumour was found in 2% of the hormonally investigated patients: Cushing's syndrome (n = 2) and phaeochromocytoma (n = 1). Eleven patients underwent adrenalectomy, but no cases of primary adrenal malignancy were observed. CONCLUSIONS Patients with adrenal incidentaloma had a low risk of developing malignancy or hormonal hypersecretion during a short-term follow-up period.

Abstract
Laparoscopic adrenalectomy is unanimously recognized as the gold standard for the treatment of adrenal tumors, but it is not indicated for tumors of any size when invasion of the surrounding tissues is clearly detected by preoperative imaging. Although laparoscopic adrenalectomy for metastatic adrenal malignancy is a feasible procedure, in the case of primary adrenal malignancy, it should be done very carefully. When laparoscopic surgery is performed for adrenal tumors >6 cm or for tumors that are considered potentially malignant after preoperative imaging or endocrine studies, the operation should be performed only by a highly skilled laparoscopic surgeon. It is also important to inform the patient and family that the tumors may be malignant and that conversion to open surgery could be necessary. The surgeon must create a sufficiently wide working space, remove the tumor and surrounding fat en bloc, and never grasp the tumor or adrenal tissue. The ultrasonically activated scalpel or ultrasonic endoaspirator should be carefully handled so that it does not touch the tumor surface because this will create a risk of tumor-cell dissemination. It also is essential not to persist unreasonably with laparoscopic procedures but to switch immediately to open surgery when laparoscopic surgery becomes difficult.

Abstract
Background Metastases from hepatocellular carcinoma (HCC) can be found in the lung and adrenal gland. We report case of a patient who presented with adrenal metastasis as the first clinical manifestation of HCC. Case presentation A patient was referred for surgical treatment for a tumor in retro-peritoneal space. The computerized tomography (CT) scan revealed a mass originating from the left adrenal gland. The patient underwent left adrenalectomy and the exploration of abdominal cavity did not reveal any other palpable lesions. Histologically, the resected lesion was a poorly differentiated metastatic tumor from HCC. Seven months later patient was readmitted complaining of cachexia, icterus, and significant weight loss. CT scan revealed hyperdense lesions of the liver Conclusion HCC may have atypical presentations like in present case. Fine needle aspiration/tru-cut® biopsy might be useful in the investigation of an accidentally discovered adrenal mass regardless of the size and can lead to the detection of a primary tumor.

Abstract
OBJECTIVES To assess the usefulness of adrenal scintigraphy for clinical evaluation of adrenal incidentalomas, and its relation with pathological diagnosis and follow-up. PATIENTS AND METHODS We have studied 46 patients with unilateral adrenal incidentaloma of size between 10 and 100 mm (average 30.5 +/- 19 mm). The lesions were discovered with abdominal computerized tomography in the study of a primary tumor (22%) or in the evaluation of benign pathology (78%). Adrenal scintigraphy assessed uptake in adrenal incidentaloma. Hormonal study included urinary catecholamines, plasma cortisol after dexamethasone, adrenal androgens, and renin and aldosterone in hypertensive patients. Five patients were operated, FNAB was carried out in three patients, and in the rest average follow-up was 29 +/- 21 months. Adrenal incidentaloma was considered nonfunctional if the lesion did not modified its size nor showed analytical alterations along a follow-up higher than 8 months. RESULTS Of 46 adrenal lesions, seven didn't show uptake (three metastases, one cyst, one adrenal carcinoma, one pheochromocytoma, and one angiomyolipoma), 34 showed excessive uptake (29 nonfunctional adrenal nodules and 5 hyperfunctional adrenal nodules), and five had normal uptake (nonfunctional adrenal nodules). Adrenal scintigraphy was compatible in all cases with cytological study or the response to chemotherapy. Along the follow-up, growth of the lesion was demonstrated in 23%, and reduction or disappearance of the lesion in 11%, with no hormonal significant changes. CONCLUSIONS Detection of a lesion with no uptake in adrenal scintigraphy forces to carry out complementary explorations in order to rule out malignant pathology. A lesion with excessive uptake is indicative of a benign process and should be assessed with hormonal determinations.

Abstract
Hypertension (HTA) is a very common disease but its origin is well known only in 1 to 5% of the cases. HTA is present in half of the patients who have an adrenal incidentaloma. Clinical data, hormonal sampling, computed tomography and adrenal scintigraphies are necessary to identify hyperfunctioning adrenal tumors. Adrenalectomy is indicated in case of potential malignant tumors and hyperfunctioning tumors. If HTA seems to be not in relation with the adrenal mass, it is recommended to recognize a congenital enzymatic block in order to ovoid an unnecessary adrenalectomy and to search for a preclinical Cushing's syndrome. The last one is associated with HTA in 91% of the cases, and with a morbid obesity, mellitus diabetes or dyslipidemia in 50% of the cases. The removal of the adrenal mass improves the HTA for half of the patients. If the adrenocortical tumor is nonfunctioning, patients have to be followed during a long time. HTA will be considered as "essential" after a new comprehensive analysis performed 3 years later.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) biopsy allows the detailed imaging and FNA not only of both intramural and extramural structures and lesions of the gastrointestinal (GI) tract but also of various intraabdominal organs. Thus, EUS-FNA biopsy offers a novel opportunity to evaluate and obtain cytology samples from adrenal gland lesions. The objective of the current study was to determine the utility of EUS-FNA in the diagnosis of adrenal lesions. METHODS The authors conducted a prospective evaluation of 24 consecutive EUS-FNA biopsy specimens obtained from patients with adrenal lesions. An attending cytopathologist was present on site to assess specimen adequacy and to provide rapid interpretation of air-dried material that had been stained with Diff-Quik (Baxter Scientific Products, McGraw Park, IL). Additional samples were obtained for ThinPrep (Cytyc Corporation, Boxborough, MA) preparation, and cell blocks subsequently were prepared. Appropriate immunohistochemical staining was performed as indicated. The cytologic diagnosis was then analyzed for correlations with the final diagnosis, which was based on relevant correlative cytologic or histologic examination of biopsied/resected pathology materials and/or final clinical follow-up. RESULTS In total, 24 EUS-FNA biopsy specimens (from 18 males and 6 females) were obtained from adrenal glands. The mean patient age was 62.2 years (range, 48-81 years). Adequate cellularity was noted in all 24 samples. Seven of 24 samples (29%) were reported to be positive for carcinoma. All samples that were diagnosed as metastatic carcinoma were confirmed on subsequent follow-up. EUS-FNA performed simultaneously with adrenal gland aspiration either from the primary site (n = 1) or from metastases to lymph nodes (n = 3) supported diagnoses of metastatic carcinoma. Six of seven samples were metastatic from the lung, and one specimen was a direct extension of a transitional renal cell carcinoma. EUS-FNA biopsy of the right adrenal gland in one patient revealed myelolipoma. In 16 patients, benign adrenal gland cells were noted on EUS-FNA biopsy specimens from enlarged adrenal glands. In 5 samples (31%), signs of adenoma were evident. Morphology alone could not distinguish between adrenal adenoma and adrenal hyperplasia. No significant complications were reported after EUS-FNA biopsy of adrenal glands. CONCLUSIONS EUS-FNA biopsy is a highly specific and safe technique for confirming the diagnosis of carcinoma metastatic to the adrenal glands. Along with cytologic evaluation, EUS imaging is needed to support the diagnosis of adrenal adenoma.

Abstract
Discerning malignancy in adrenal tumors largely influences disease management and is, therefore, of utmost importance to both patient and physician. Clinical presentation (e.g. virilization) and baseline hormonal evaluation (e.g. high serum DHEAS) are occasionally of great value but usually provide only limited help in predicting malignancy. The probability of malignancy is clearly related to tumor size, as almost all lesions <3 cm are benign whereas a diameter of >6 cm indicates a high risk of malignancy. Computed tomography (CT) and magnetic resonance imaging (MRI) both contribute significantly to the characterization of adrenal masses. If the attenuation of a homogeneous mass with smooth border is 10 Hounsfield units or less in unenhanced CT the diagnosis of a lipid rich adenoma is established. Similarly, enhancement washout of more than 50% in CT at 10-15 min suggests a benign lesion. In MRI both rapid contrast enhancement after gadolinium followed by rapid washout and signal intensity loss using opposed-phase image in chemical shift analysis also indicate the presence of an adenoma. In contrast, adrenal carcinomas--but also pheochromocytomas--typically present as inhomogeneous lesion with intermediate-to-high intensity on T2 images in MRI. Margins and enhancement after contrast media in CT are irregular in adrenal carcinoma. Other imaging techniques either offer little additional information (NP-59 scintigraphy) or have not yet been fully established (positron emission tomography). Fine needle aspiration/cut biopsy is at present restricted to patients with a known extra-adrenal malignancy and suspected adrenal metastasis as the only evidence of disseminated disease. Adrenal tumors classified as benign undergo follow-up imaging to assess tumor growth. If an increase in diameter of >1 cm is seen, surgical removal is recommended. Even after tumor removal the diagnosis of dignity may remain difficult. Diagnostic scores together with new immunohistological markers are the methods of choice to assess malignancy. In conclusion, an interdisciplinary approach with a structured use of available diagnostic tools is needed to classify adrenal tumors correctly.

Abstract
Clinically inapparent adrenal masses are incidentally detected after imaging studies conducted for reasons other than the evaluation of the adrenal glands. They have frequently been referred to as adrenal incidentalomas. In preparation for a National Institutes of Health State-of-the-Science Conference on this topic, extensive literature research, including Medline, BIOSIS, and Embase between 1966 and July 2002, as well as references of published metaanalyses and selected review articles identified more than 5400 citations. Based on 699 articles that were retrieved for further examination, we provide a comprehensive update of the diagnostic and therapeutic approaches focusing on endocrine and radiological features as well as surgical options. In addition, we present recent developments in the discovery of tumor markers, endocrine testing for subclinical disease including autonomous glucocorticoid hypersecretion and silent pheochromocytoma, novel imaging techniques, and minimally invasive surgery. Based on the statements of the conference, the available literature, and ongoing studies, our aim is to provide practical recommendations for the management of this common entity and to highlight areas for future studies and research.

Abstract
PURPOSE OF REVIEW Adrenocortical cancer (ACC) is an uncommon disorder that remains a challenge to the surgeon and oncologist. When the disease is localized to the adrenal gland and readily amenable to surgical resection, reasonable 5-year survival rates are possible. Locally invasive disease carries a poorer prognosis, and metastatic disease is uniformly fatal within 1 year. In this review, we summarize the current knowledge regarding the clinical management of ACC and the molecular mechanisms underlying the disease. RECENT FINDINGS The clinical manifestations, staging, and current treatment for ACC has been well documented. Surgery is still the mainstay of treatment, but identifying molecular targets for chemotherapeutic agents or monoclonal antibodies would be a great advance. At present, our understanding of pathogenic mechanisms is crude; however, the molecular events regulating this aggressive disease are beginning to emerge, especially in the last few years. The advent of laparoscopic adrenalectomy has also created its own dilemmas regarding the appropriate surgical approach to the large, potentially malignant adrenal mass. SUMMARY The challenge in the management of this disease lies in understanding the molecular mechanisms that underlie the development of ACC with the diagnostic and therapeutic benefits that would ensue.

Abstract
OBJECTIVE To assess our current concept and results of transperitoneal laparoscopic adrenalectomy (TPLA) and retroperitoneal endoscopic adrenalectomy (ERA) for a variety of benign disorders of the adrenal glands. BACKGROUND DATA According to the literature, minimal invasive adrenalectomy has shown to be a safe and effective surgical alternative to open adrenalectomy. Both, transperitoneal and retroperitoneal endoscopic minimal invasive access are currently used for surgical removal of benign adrenal tumors. There is still some debate about the indications and the access used for a minimal invasive approach. PATIENTS AND METHODS Treatment and clinical outcome of all patients who underwent either transperitoneal laparoscopic or endoscopic retroperitoneal adrenalectomies for benign diseases from February 1997 to August 2002 were analyzed retrospectively. RESULTS Twenty-six minimal invasive adrenalectomies were performed in 23 patients with a mean age of 57 years. Whereas 11 patients underwent unilateral right- sided ERA, unilateral TPLA was performed in 9 patients on the left side. Three patients had bilateral TPLA. The mean operating time for unilateral ERA and TPLA was 114 and 79 min, respectively. Bilateral TPLA was prolonged to 223 min operating time. There were only two minor postoperative complications. The mean hospital stay for unilateral TPLA, ERA and bilateral TPLA was 4.7, 5 and 6 days, respectively. There was no mortality. CONCLUSION Both, ERA and TPLA are safe and clinically effective treatment modalities for benign disorders of the adrenal glands. We currently favor a transperitoneal laparoscopic approach for bilateral and left-sided adrenal tumors, whereas right-sided tumors <8 cm are removed by a retroperitoneal approach. Large right-sided tumors >8 cm are better removed by transperitoneal access.

Abstract
AIM The aim of this study was to compare the usefulness of computed tomography (CT)-scan, magnetic resonance imaging (MRI), and fine-needle aspiration (FNA) cytology in patients with incidentally discovered adrenal masses. PATIENTS AND METHODS Thirty-four consecutive patients (six men and 28 women, median age of 47 years, range 26-80) with non-functioning adrenal masses of 2 cm or more (median 3.5 cm, range 2-9) were studied. All patients underwent CT-scan, MRI, and image-guided FNA cytology using spinal-type narrow-gauge needles prior to further procedures. Nineteen patients underwent adrenalectomy. RESULTS Final pathology showed 13 benign adrenal lesions, four adrenocortical carcinomas, and two unsuspected adrenal metastases. Fifteen patients who did not have surgery were considered definitively as having benign adrenal lesions since the mass was unchanged on CT-scans performed during follow-up. The sensitivity, specificity, and positive predictive value were 66.7, 85.7, and 50.0%, for CT-scan, 83.3, 92.9, and 71.4% for MRI, and 83.3, 100, and 100% (p<0.05) for FNA cytology, respectively. CONCLUSIONS Image-guided FNA cytology is a safe and sensitive procedure that may reveal unsuspected adrenal malignancies, and should be performed in all patients with incidentally discovered adrenal masses of more than 2 cm in size.
