Adrenocortical carcinoma: what the surgeon needs to know. Case report and literature review

Primary Adrenal Angiosarcoma and its Management: A Case Report

Primary adrenal angiosarcoma is a very rare malignancy. This is a case report of a 54-year-old female, who presented with right-sided abdominal pain. Magnetic resonance imaging of the abdomen and pelvis showed a right adrenal mass with a maximum dimension of 5.7 cm. The patient went for a laparoscopic right adrenalectomy. The postoperative period was uneventful, and she was discharged on postoperative day 2. The patient was free from complaints at outpatient follow-up visits. Pathology confirmed the diagnosis of adrenal angiosarcoma and the metastasis workup was negative. A multidisciplinary approach through the expertise of medical oncology, surgical oncology, and histopathology is essential for the diagnosis and management of such rare diseases.

Effective multimodal management of a giant adrenocortical carcinoma

BACKGROUND

Adrenocortical carcinoma is a rare and aggressive tumour. The only curative treatment is surgery with negative margins. In most series, the average lesion size ranges from 5.5 to 15 cm.

METHODS

We report the case of a 27-year-old female with hyperandrogenism and Cushing syndrome due to a right adrenocortical carcinoma of 19.7 cm.

RESULTS

The tumour abutting on liver and vena cava and the presence two nodules in liver required extensive surgery including a right posterior sectionectomy and an en bloc resection of the adrenal mass together with the right kidney and the gallbladder. The vena cava was also resected with a reconstruction using a pericardial patch since it was invaded on its border. Pathological examination confirmed an adrenocortical carcinoma, with tumour invasion of vessels, tumour capsule, vena cava and two metastases in the liver (pT4N0M1). All margins were negative. Three months after surgery, two lung nodules, cardio-phrenic and internal mammary adenomegalies were noticed on a PET/CT scan, justifying the initiation of chemotherapy, alongside with mitotane. After a 10-month follow-up, CT scan was stable excepted for a lung nodule growing from 4 to 7 mm. Targeted stereotaxic radiotherapy was then administered. Twenty-two months after surgery, the patient has improved considerably and all signs of hyperandrogenism and Cushing syndrome have resolved.

CONCLUSION

This case of adrenocortical carcinoma illustrates one of the largest tumours among those reported. It demonstrates the feasibility and effectiveness of a multimodal approach in its treatment even if it is giant and at high risk.

Comparison of surgical outcomes between 3-dimensional and 2-dimensional laparoscopy of ovarian cyst (LOOC): a randomised controlled trial

The purpose of this study was to compare the surgical outcomes and efficacy of 3-dimensional (3D) versus 2-dimensional (2D) imaging systems for the treatment of ovarian cyst. A total of 46 patients undergoing a laparoscopic ovarian cystectomy were randomly assigned to either the 3D or 2D laparoscopy group. The primary outcome measure was the operative blood loss. The secondary outcome measure was visually induced motion sickness (VIMS), task efficacy during laparoscopy, and postoperative complication. There were no differences in baseline demographics between the two groups. The operative blood loss was significantly smaller in the 3D groups (28.7 ± 11.6 mL) than in the 2D groups (46.5 ± 24.4 mL) (p = .012). VIMS score was significantly higher in the 3D groups than the 2D groups (p < .001). 3D laparoscopy was superior to 2D in terms of the task efficacy of ovarian cyst enucleation (p < .001), adhesiolysis or dissection (p < .001), and ovarian suturing (p = .008). None of the patients in both groups developed operative complications. In conclusion, a 3D imaging system showed a more favourable surgical outcome and improved task efficacy than 2D in laparoscopic ovarian cystectomy. However, 3D laparoscopy tends to cause more frequent VIMS in surgeons.Impact statementWhat is already known on this subject? Several studies examining the possible benefits and drawbacks of a 3D imaging system versus 2D in laparoscopic surgery have brought about conflicting results. However, there have been few studies comparing the surgical outcomes of 3D and 2D laparoscopic ovarian cystectomy.What do the results of this study add? 3D laparoscopy showed favourable surgical outcomes and improved task efficacy than 2D laparoscopy in ovarian cystectomy.What are the implications of these findings for clinical practice and/or further research? More complex procedures, such as suturing and adhesiolysis, might be easier to perform with 3D laparoscopy than with 2D laparoscopy. Therefore, further large studies of 3D gynaecologic laparoscopy with different complexities and for surgeons with different surgical skills are needed.

Giant Adrenocortical Carcinoma: A Case Report and Review of the Relevant Literature

BACKGROUND Adrenocortical carcinomas are rare and aggressive tumors often diagnosed as incidentalomas. The malignancy can present with abnormal hormone secretion or the tumor may be non-functioning and present as a palpable mass causing discomfort. Here, we present a case of an adrenal cortical carcinoma originally identified as an incidentaloma. CASE REPORT A 63-year-old woman presented with abdominal pain and discomfort. A large abdominal mass, occupying the left upper and lower quadrant, was palpated. Imaging revealed a mass occupying the left abdomen between the stomach and the spleen, applying pressure on the pylorus, duodenum, splenic vessels, and pancreas. The mass size was 21.2×13×14.6 cm. Hormonal investigations were normal. Surgical exploration was performed, and the tumor was excised. Pathological analysis revealed an adrenocortical carcinoma and the patient underwent adjuvant chemotherapy. Twelve months later, the carcinoma recurred. The patient underwent a second operation in which the recurrent mass was excised along with the tail of the pancreas and a small part of the left lobe of the liver. The postoperative period was uneventful, and the patient was discharged home on the 7th postoperative day. No further adjuvant therapy was applied. The patient remains disease-free 18 months after the reoperation. CONCLUSIONS Giant adrenocortical carcinomas, although rare, pose a challenge to the surgical team both diagnostically and therapeutically. Surgical excision with the appropriate oncologic support can guarantee excellent outcomes.

Adrenal cortical carcinoma: pathology, genomics, prognosis, imaging features, and mimics with impact on management

Adrenocortical carcinoma (ACC) is a rare tumor with a poor prognosis. Most tumors are either metastatic or locally invasive at the time of diagnosis. Differentiation between ACC and other adrenal masses depends on clinical, biochemical, and imaging factors. This review will discuss the genetics, pathological, and imaging feature of ACC.

A case report of primary adrenal angiosarcoma as depicted on magnetic resonance imaging

RATIONALE

Angiosarcoma is an extremely rare malignant tumor of endothelial origin. The majority of studies reporting angiosarcoma have been concerned with the clinical and pathological aspects, with limited reporting of their imaging findings. To our knowledge, angiosarcoma of the adrenal gland is very rare. Herein we firstly report a primary adrenal angiosarcoma depicted on magnetic resonance imaging (MRI).

PATIENT CONCERNS

A 59-year-old man was referred to our hospital for 1 year left-flank pain that exacerbated in recent 4 months.

DIAGNOSIS

A regular mass with clear boundary was revealed on MRI in the region of left adrenal gland. Its signal intensity was inhomogeneous. It mainly showed isointensity with patchy slight hyperintensity on T1-weighted images and marked hyperintensity with patchy hypointensity on T2-weighted images. On contrast-enhanced images, it demonstrated significantly heterogeneous enhancement, and the peripheral solid component showed delayed enhancement. Bulky blood vessels and hemorrhage were identified in the tumor.

INTERVENTIONS

The mass was surgically excised under a left laparoscopic adrenalectomy.

OUTCOMES

Left adrenal angiosarcoma was confirmed by pathological and immunohistochemical examinations. No evidence of recurrence was found 6 months after operation.

LESSONS

In conclusion, primary adrenal angiosarcoma has some MRI features corresponding to its pathological nature. It should be included in the differential diagnosis when a mass was detected in the adrenal gland.

Uncommon primary hydatid cyst occupying the adrenal gland space, treated with laparoscopic surgical approach in an old patient

Hydatid disease (HD) is caused by Echinococcus Granulosus (EG), which is a larva endemic in many undeveloped areas. The most common target is the liver (59%–75%). The retroperitoneal space is considered as a rare localization. We report an uncommon case of HD located in the adrenal gland space.

Presentation of case. This is a 78-year-old Moroccan woman, with right flank pain for eight months previously. She denied contact with dogs or sheep. Her physical examination was normal. There was no pathological alteration of laboratory exams. CT scan measuring 5 cm without clear signs for a sure diagnosis found a round lesion in the right adrenal gland. An abdominal MRI showed a round mass of 34 x 27 mm with fluid component without a clear plane of dissection from kidney and liver. A laparoscopic procedure was performed to obtain a histological diagnosis. We reached a conclusive diagnosis of Hydatid cyst of right adrenal gland space.

Hydatid cysts often develop in the liver. The location in the adrenal bed is rare without clinical signs related to alteration of the gland’s secretion. Hydatid cyst identification in the adrenal gland space is based on ultrasonography, CT or MRI scans. The differential diagnosis includes various benign and malignant lesions. Laparoscopic procedure is the best approach available to obtain a histological diagnosis and a curative treatment.

The best treatment for HD is the pericystectomy. Laparoscopic surgery can guarantee a radical resection of these lesions when it performed by an expert surgeon.

Endoscopic diagnosis and treatment of neuroendocrine tumors of the digestive system

The authors evaluated the role of endoscopic techniques in the diagnosis and in the potential treatment of neuroendocrine tumors (NET) localized in the gastro-entero-pancreatic system, on the basis of their experience and of the international literature. NET are rare tumors that arise from neuroendocrine cells of the gastrointestinal tract and pancreas. It is a possibility that both the digestive endoscopy and EUS play an important role in the diagnosis, staging and surveillance of this disease. In some cases, especially in the early stages, surgical endoscopy allows the treatment of such tumors.

Pancreatic stump closure after pancreatoduodenectomy in elderly patients: a retrospective clinical study

BACKGROUND

Pancreatic fistula (PF) after pancreatoduodenectomy (PD) represents the major source of morbidity. Derivative procedures are preferred by pancreatic surgeons, but the optimal management of remnant pancreatic stump remains controversial.

AIMS

The purpose of this retrospective study is to evaluate the efficacy and safety of pancreatic stump closure in selected elderly patients (>65 years).

METHODS

Clinical data of 44 PD undergone mechanical closure of the pancreatic stump performed between 2001 and 2014 in two department of general and oncologic surgery were retrospectively collected. Considering the age, patients were divided into two groups: 21 patients of less than 65 years (Group A) and 23 patients of more than 65 years (Group B).

RESULTS

A soft pancreatic parenchyma with a not-dilated duct (diameter <3 mm) was reported in all the 44 patients. A grade-A PF, which did not required further treatments, developed in 20 cases (45.4%; 13 in group A and 7 in group B; p < 0.05), grade-B in 5 patients (11.4%; 3 in group A and 2 in group B; statistically not significant) and a grade-C PF was observed only in one patient (2.2%; 1 in group A and 0 in group B).

DISCUSSION

In selected "high risk" elderly patients (>65 years) with soft pancreatic texture, the closure of the pancreatic stump can be a useful tool in the surgical armamentarium with the aim to reduce the incidence of age-related complications.

CONCLUSIONS

Prospective randomized controlled trial to better evaluate PF risk factors is needed.

Three-dimensional (3D) versus two-dimensional (2D) laparoscopic adrenalectomy: A case-control study

INTRODUCTION

Laparoscopic adrenalectomy is today considered the gold standard of treatment for adrenal tumors. The development of high definition cameras does not eliminate the major limitation of two-dimensional (2D) laparoscopy: lack of depth perception and loss of spatial orientation. Tree-dimensional (3D) HD laparoscopy was developed as an alternative to conventional 2D laparoscopy.

METHODS

We report our experience with use of 3D vision system for laparoscopic adrenalectomy. Between January 2009 and March 2015 we performed a total of 52 laparoscopic adrenalectomies. In this case-control study we considered 13 laparoscopic adrenalectomies performed with three-dimensional (3D) vision system as case group. The last 26 procedures made with two-dimensional (2D) HD laparoscopic system represented the control group. We considered primary end-points: operative time, intraoperative complications and conversion rate. We evaluated also quality of depth perception and surgical strain.

RESULTS

Although the operative time for the entire surgical procedure was shorter in 3D group, there were no significant differences. The surgeon experienced better depth perception with 3D system and subjectively reported less strain using 3D vision system. Residents and medical students confirmed these data on surgical outcome.

CONCLUSION

3D system vision does not seem to influence the operative time of laparoscopic adrenalectomy performed by experienced surgeon because the surgical technique request simple tasks. We obtain the better visualization in depth perception with effect on surgical precision. Comparative studies are necessary to verify if 3D can reduce perioperative complication with similar operative time.

Large cavernous hemangioma of the adrenal gland: Laparoscopic treatment. Report of a case

•

Identify the preoperative radiologic features of adrenal hemangioma.

•

We examine the better surgical approach for adrenal tumors and adrenal hemangioma.

•

Controindication to laparoscopic adrenalectomy.

Introduction

Cavernous hemangioma of the adrenal gland is a rare benign tumor. The diagnosis is often postoperative on histological exam with the presence of blood-filled, dilated vascular spaces.

Presentation of case

We report the clinical case of a 49 years-old woman who came to our observation with aspecific abdominal pain. A computed tomography (CT) abdominal scan revealed a 11 cm right adrenal mass. This lesion was well circumscribed, round, encapsulated. After iodinated-contrast we observed a progressive, inhomogeneous enhancement without evidence of active bleeding and with pre-operative diagnosis of adrenal hemangioma. Laparoscopic adrenalectomy was performed by a transperitoneal flank approach. Pathological examination revealed a 11 cm adrenal mass with extensive central necrotic areas mixed to sinusoidal dilation and fibrotic septa. Postoperative diagnosis was adrenal hemangioma.

Discussion

Adrenal hemangiomas occur infrequently. Generally these adrenal masses are non-functioning and there is no specific symptoms. Recent records demonstrate that laparoscopic adrenalectomy is technically safe and feasible for large adrenal tumors, but controversy exists in cases of suspected malignancy. We choose laparoscopic approach to adrenal gland on the basis of preoperative CT abdominal scan that excludes radiological signs of adrenocortical carcinoma (ACC) such as peri-adrenal infiltration and vascular invasion.

Conclusion

Laparoscopic adrenalectomy is considered the standard treatment in case of diagnosis of benign lesions. In this case report we discussed a large adrenal cavernous hemangioma treated with laparoscopic approach. Fundamental is the study of preoperative endocrine disorders and radiologic findings to exclude signs of malignancy.

Giant nonfunctioning adrenocortical carcinoma: a case report and review of the literature

BACKGROUND

Adrenocortical carcinoma is a rare and aggressive malignancy. Patients usually present early with manifestation of abnormal hormone secretion. However, adrenocortical carcinoma can also be nonfunctioning, and such patients present late with a mass effect or distant metastases.

CASE PRESENTATION

We herein report a case of a 30-year-old Sri-Lankan woman who presented with a 3-month history of left flank pain associated with nausea, vomiting, and weight loss. Imaging revealed a large left upper quadrant mass with a 1.8-cm left lung nodule. The differential diagnoses included a left adrenal mass, left upper pole renal mass, and retroperitoneal sarcoma. A functional adrenal work-up revealed no abnormal findings. Surgical excision of the mass was uneventful with no postoperative complications. Pathological analysis revealed a nonfunctioning adrenocortical carcinoma measuring 16 × 14 × 10 cm. To our knowledge, a mass of this size is among the largest nonfunctioning adrenocortical carcinomas reported in the published literature. The investigations and approach to treatment were consistent with those in the published literature.

CONCLUSION

Large nonfunctioning adrenocortical carcinomas pose a diagnostic and therapeutic challenge, and most are diagnosed at a late stage. Appropriate imaging and functional work-up of the mass are vital before treatment. Surgical excision is safe, even for large adrenocortical carcinomas; excision in patients with advanced disease has been shown to have the best outcomes.
