Abstract
BACKGROUND Ultrasonography (US) represents the gold standard imaging method for the assessment of testicular lesions (TL). The gray-scale (GSUS) and color-Doppler (CDUS) ultrasound examination allow sonographers to investigate the size, margins, echotexture, and vascular features of TLs with the aim to differentiate benign from malignant lesions. Recently, the use of contrast-enhanced US (CEUS) and sonoelastography (SE) has led to further improvements in the differential diagnosis of TL. Although GSUS and CDUS are often sufficient to suggest the benign or malignant nature of the TL, CEUS can be decisive in the differential diagnosis of unclear findings, while SE can help to strengthen the diagnosis. The contemporary combination of GSUS, CDUS, CEUS, and SE has led to a new diagnostic paradigm named multiparametric US (mp-US), which is able to provide a more detailed characterization of TLs than single techniques alone. This narrative and pictorial review aimed to describe the mp-US appearance of several TLs. METHODS An extensive Medline search was performed to identify studies in the English language focusing on the mp-US evaluation of TLs. RESULTS A practical mp-US "identity card" and iconographic characterization of several benign and malignant TLs is provided herein. CONCLUSIONS The mp-US characterization of TL reported herein can be useful in daily clinical practice.

Abstract
Recent reports indicate an increase in Leydig cell tumor (LCT) incidence. Radical orchiectomy is the standard therapy in children and adults, although it entails physical and psychosocial side effects. Testis-sparing surgery can be a consideration for benign LCT of 2.5 cm or less in size. Malignant LCTs respond poorly to conventional chemotherapy, so new treatment modalities are needed. In this study, we observed increased histidine decarboxylase expression and pro-angiogenic potential in LCT surgically resected from pediatric patients (fetal to pubertal) vs control samples from patients without endocrine or metabolic disorders which were collected at necropsy. We, therefore, evaluated for the first time the antitumor efficacy of two histidine decarboxylase inhibitors (α-methyl-dl-histidine dihydrochloride (α-MHD) and epigallocatechin gallate (EGCG)), alone and combined with carboplatin, in two preclinical models of LCT. MA-10 and R2C Leydig tumor cells, representing two different LCT subtypes, were used to generate syngeneic and xenograft mouse LCT models, respectively. In the syngeneic model, monotherapy with α-MHD effectively reduced tumor growth and angiogenesis. In the xenografts, which showed co-expression of histidine decarboxylase and CYP19, the combination of EGCG plus carboplatin was the most effective therapy, leading to LCT growth arrest and undetectable levels of plasmatic estradiol. Testicular and body weights remained unaltered. On the basis of this study, histidine decarboxylase may emerge as a novel pharmacological target for LCT treatment.

Leydig Cell Tumors of the Testis: An Update of the Imaging Characteristics of a Not So Rare Lesion. Cancers (Basel) 2022; 14:cancers14153652. [PMID: 35954321 PMCID: PMC9367522 DOI: 10.3390/cancers14153652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Revised: 07/24/2022] [Accepted: 07/25/2022] [Indexed: 12/02/2022] Open
Abstract
Simple Summary Stromal tumors of the testis are rare. However, among this group, Leydig cell tumors (LCT) are the most frequent, and recent studies suggest that LCTs account for up to 22% of small testicular nodules. It is now accepted that small LCTs can benefit from testis-sparing surgery or in some selected cases radiological surveillance. Since percutaneous testicular biopsy is still not recommended, the diagnosis of LCT rests on multimodal imaging techniques. Therefore, it is essential for the radiologist and the urologist to know the main imaging features of LCTs in ultrasound and MRI. Abstract Pre-operative testicular tumor characterization is a challenge for radiologists and urologists. New data concerning imaging approaches or immunochemistry markers improve the management of patients presenting with a testicular tumor, sometimes avoiding radical orchiectomy. In the past 20 years, imaging modalities, especially ultrasound (US) and magnetic resonance imaging (MRI), improved, allowing for great progress in lesion characterization. Leydig cell tumors (LCT) are rare testicular tumors developing from the stromal tissue, with relatively scarce literature, as most of the studies focus on the much more frequent germ cell tumors. However, with the increase in testicular sonography numbers, the incidence of LCT appears much higher than expected, with some studies reporting up to 22% of small testicular nodules. Multimodal ultrasound using Doppler, Elastography, or injection of contrast media can provide crucial arguments to differentiate LCT from germ cell tumors. Multiparametric MRI is a second intention exam, but it allows for extraction of quantifiable data to assess the diagnosis of LCT. The aims of this article are to review the latest data regarding LCT imaging features, using multimodal ultrasound and multiparametric MRI, and to focus on the peculiar aspect of the testis of patients with Klinefelter’s syndrome. The possibility of an LCT should be raised in front of a small hypoechoic tumor with a marked corbelling hypervascularization in an otherwise normal testicular pulp. Ultrasonographic modules, such as ultrasensitive Doppler, contrast-enhanced ultrasonography, or elastography, can be used to reinforce the suspicion of LCT. MRI provides objective data regarding vascularization and enhancement kinetics.

Abstract
Sonography with a high-frequency transducer is the modality of choice for imaging the scrotum. Most intratesticular lesions are hypoechoic. Differentiation of intratesticular hypoechoic lesions as either malignant or benign is important because the treatment of these lesions vary. In this paper, we review the sonographic features of different types of intratesticular hypoechoic lesions, such as testicular cysts, testicular tumors, testicular inflammatory lesions, segmental testicular infarction, and testicular trauma.

Abstract
Abstract
Background
Leydig cell tumors (LCTs) represent the most common form of stromal tumors. We reported the 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) findings of a patient with testicular LCT.
Case presentation
A 50-year-old man with a history of end-stage renal disease and renal transplantation 19 years ago. One year earlier, he started to have a chronic rejection. During the investigation to determine the cause of chronic rejection, a suspicious lesion in the graft with a collection around it was seen on ultrasound (US) images, raising the possibility of post-transplant lymphoproliferative disorder (PTLD). The patient was referred for further evaluation by whole body 18F-FDG PET/CT imaging. The image finding revealed an incidental hypermetabolic focal lesion in the right testicle—no other specific findings in the remaining parts of the body nor definitive FDG avid lymphadenopathy to suggest PTLD. Testicular US was requested and showed a well-defined right-sided heterogeneous hypoechoic intratesticular focal mass at the upper pole of the right testis with significant internal vascularity on the color Doppler imaging. The patient underwent a right radical orchidectomy, and the tumor was pathologically confirmed as an LCT.
Conclusion
In our case, 18F-FDG-PET/CT has been helpful in incidentally detecting this rare testicular tumor in a patient with suspected PTLD.

Abstract
RATIONALE Testicular tumors represent 1% to 1.5% of all tumors in men. Those derived from Leydig cells are rare and account for 1% of testicular tumors. Leydig tumor cells can produce steroid hormones such as estrogen, progesterone and testosterone. The amount and type of hormones secreted by these tumors may produce complicated clinical characteristics in these patients. PATIENT CONCERNS Here, we report a patient with azoospermia, a testicular Leydig cell tumor (LCT), and elevated plasma testosterone levels. We describe the diagnostic and therapeutic experience of this case, and our follow-up of the patient's clinical indicators and fertility status. DIAGNOSIS The patient was diagnosed with azoospermia and a testicular LCT. INTERVENTIONS The patient underwent testicular tumor removal and long-term follow-up. OUTCOMES After 4 months of follow-up, the patient's semen examination index significantly improved and his wife became naturally pregnant. At 4 months of gestation, the fetus was delivered because of a ruptured amniotic cavity. Twenty-six months after tumor removal, the patient's sex hormone levels had completely returned to normal and spermatogenic function had partially recovered, but there was no natural pregnancy with his partner. CONCLUSION For LCTs, testis sparing surgery may provide a safe and feasible option to restore spermatogenic function, although longer-term follow-up is required. Drug assistance may be required to maintain spermatogenic function and achieve fertility, and further research is required.

Abstract
Leydig cell tumors (LCT) are the most common type of testicular stromal tumor. Herein, we investigate the G protein-coupled estrogen receptor (GPER) and peroxisome proliferator-activated receptor (PPAR) implication in regulation of lipid homeostasis including the expression of steroidogenesis-controlling molecules in clinical specimens of LCTs and tumor Leydig cells (MA-10). We showed the general structure and morphology of LCTs by scanning electron and light microscopy. In LCTs, mRNA and protein analyses revealed increased expression of GPER and decreased expression of PPARα, β, and γ. Concomitantly, changes in expression pattern of the lutropin receptor (LHR), protein kinase A (PKA), perilipin (PLIN), hormone sensitive lipase (HSL), steroidogenic acute regulatory protein (StAR), translocator protein (TSPO), HMG-CoA synthase, and reductase (HMGCS, HMGCR) were observed. Using MA-10 cells treated with GPER and PPAR antagonists (alone and in combination), we demonstrated GPER-PPAR-mediated control of estradiol secretion via GPER-PPARα and cyclic guanosine monophosphate (cGMP) concentration via GPER-PPARγ. It is assumed that GPER and PPAR can crosstalk, and this can be altered in LCT, resulting in a perturbed lipid balance and steroidogenesis. In LCTs, the phosphatidylinositol-3-kinase (PI3K)-Akt-mTOR pathway was disturbed. Thus, PI3K-Akt-mTOR with cGMP can play a role in LCT outcome and biology including lipid metabolism.

Abstract
PURPOSE Testicular adrenal rests tumor (TART) is a rare kind of benign tumor in the testis. It usually occurred secondary to congenital adrenal hyperplasia (CAH), a hormonal disorder caused by hydroxylase deficiency. As the first-line examination method, ultrasound provides crucial diagnostic information for TART, although misdiagnosis to malignancy is quite common because of its rare prevalence. We aimed to summarize the sonographic manifestations of TART to improve the diagnostic accuracy and specificity. METHODS Eight CAH patients with TART identified by ultrasound in our medical center were retrospectively reviewed. Clinical and hormonal profile, semen analysis and treatment choices were collected. Sonographic examinations were performed at the first evaluation and interpreted by experienced radiologists individually. All patients received regular follow-up, and 5 patients undertook repeated scrotal ultrasound. A literature review of TART in CAH patients was conducted, with 123 patients from 23 articles since 1990 included. RESULTS A total of 8 patients aged between 4 to 27 years old were enrolled. 7 of 8 (87.5%) patients exhibited bilateral testicular lesions. The sizes of the testicular lesions were between 0.18 ml to 5.68 ml, and all showed a clear boundary. 10/15 (66.7%) lesions were homogenously hypoechoic, 4/15 (26.7%) were heterogeneously iso-hypoechoic, and 1/15 (6.7%) were homogenously isoechoic. 10/15 (66.7%) lesions were hyper-vascular. The longitudinal follow-up of 5 patients showed testicular lesions changed in terms of size, echogenicity, and vascularity after steroid treatment. A potential correlation may exist between ACTH levels and tumor size (p = 0.066). From the literature review, 100/123 (81%) patients got bilateral lesions, and 95% of them were located near the mediastinum. 80/103 (78%) lesions exhibited a clear boundary, and predominant lesions (74%) were hypoechogenic. Vascularity was with great diversity. Seventy-nine lesions of 44 patients were followed-up by scrotal ultrasound, among which 29 (37%) remained unchanged, 29(37%) shrank, and 21(27%) disappeared. CONCLUSIONS Key sonographic characteristics of TART are: resembled lesions on both testes, located near the mediastinum, clear boundary, and changed in size or echogenicity after steroid treatment. These features can help radiologists to make an accurate diagnosis of TART.

Histamine H4 receptor as a novel therapeutic target for the treatment of Leydig-cell tumours in prepubertal boys. Eur J Cancer 2018; 91:125-135.

Abstract
Leydig-cell tumours (LCTs) are rare endocrine tumours of the testicular interstitium, with recent increased incidence. Symptoms include precocious puberty in children; and erectile dysfunction, infertility and/or gynaecomastia, in adults. So far, scientific evidence points to aromatase (CYP19) overexpression and excessive oestrogen and insulin-like growth factor (IGF) -1 production as responsible for Leydig-cell tumourigenesis. LCTs are usually benign; however, malignant LCTs respond poorly to chemo/radiotherapy, highlighting the need to identify novel targets for treatment. Herein, we investigated the potential role of the histamine receptor H4 (HRH4) as a therapeutic target for LCTs using R2C rat Leydig tumour cells, a well-documented in vitro model for Leydigioma. Also, we studied for the first time the expression of CYP19, IGF-1R, oestrogen receptor (ER) α, ERβ, androgen receptor (AR) and HRH4 in human prepubertal LCTs versus normal prepubertal testes (NPTs). HRH4 agonist treatment inhibited steroidogenesis and proliferation in R2C cells and also negatively affected their pro-angiogenic capacity in vitro and in vivo, as assessed by evaluating the proliferative activity of human umbilical vein endothelial cells and by means of the quail chorioallantoic membrane assay, respectively. Moreover, E2 and IGF-1 inhibited HRH4 mRNA and protein levels. In human prepubertal LCTs, CYP19, IGF-1R, ERα and ERβ were overexpressed compared with NPTs. In contrast, HRH4 staining was weak in LCTs, but moderate/strong and confined to the interstitium in NPTs. Importantly, HRH4 was absent or barely detectable in seminiferous tubules or germ cells. Overall, our results point to HRH4 as a novel therapeutic target in LCTs.

Abstract
Testicular yolk sac tumors are rare, and analyses of relevant ultrasound (US) findings are limited. We retrospectively reviewed the US features of 21 pathologically verified cases (patients aged 10-64 months). Neoplasms were unilateral and solitary, occupying part (focal) or all (diffuse) of the testis. Focal lesions (14 cases) were usually solid and ovoid, with a homogeneous echo texture or multiple random anechoic spaces, and hypervascular. Diffuse neoplasms had heterogeneous echo textures; most were hypervascular. On spectral Doppler US imaging, 11 cases had a mean peak systolic velocity of 12.9 cm/s and a mean resistive index of 0.54. Ultrasound is a useful tool for imaging pediatric testes when a yolk sac tumor is suspected.

Abstract
Background Ultrasensitive Doppler is a novel non-invasive ultrasound (US) Doppler technique that improves sensitivity and resolution for the detection of slow flow. Purpose To investigate the feasibility of ultrasensitive Doppler (USD) for testicular disease diagnosis, using both qualitative and quantitative results. Material and Methods This prospective study was conducted in 160 successive men referred for scrotal US including B-mode and conventional Color-Doppler. A new USD sequence and algorithm dedicated to academic research were implemented into the US system. The quality criterion for a successful examination was the detection of well delineated intratesticular vessels. Qualitative USD results were described in terms of tumor vascular architecture and flow intensity for different pathologies for 41 patients. The testicular vascularization (TV), defined as a vessel's surface ratio, was quantified using customized MATLAB® software and compared in azoospermic and normal patients. Results USD was acquired successfully in 153/160 patients (95.6%). The tumor vascular architecture differed depending on the nature of the tumors. Leydig cell tumors exhibited mostly circumferential vascularization, while germ cell tumors exhibited straight vessels through the tumors, or anarchic vascular maps. USD improved the diagnostic performance of testicular Doppler US in a case of incomplete spermatic cord torsion and acute epididymitis. The reproducibility of TV measurements established an interclass correlation of 0.801. Non-Klinefelter syndrome non-obstructive azoospermia patients exhibited a lower TV compared to normal patients, to Klinefelter syndrome, and to obstructive azoospermia patients ( P < 0.002, P < 0.005, and P < 0.05, respectively). Conclusion Testicular USD can become a promising technique for improving US diagnosis of tumors, acute scrotum, and for determining infertility status.

Abstract
The Fischer 344 (F344) rat was used by the National Toxicology Program (NTP) for over 5 decades for toxicity and carcinogenicity studies. However, in 2006, the NTP decided to switch to a different rat stock due largely to high background control incidences of Leydig cell tumors (LCTs) and mononuclear cell leukemia (MNCL), also known as large granular lymphocytic (LGL) leukemia. In the current review, we aim (1) to provide a summary of NTP bioassays with treatment-associated effects involving MNCL and LCTs in addition to male F344-specific tunica vaginalis mesothelioma (TVM); (2) to describe important pathobiological differences between these F344 rat tumor responses and similar target tissue-tumor response in humans; and (3) to present the NTP reasons for switching away from the F344 rat. We show that due to the highly variable background incidence of F344 MNCL, more reliance on historical control data than is usual for most tumor responses is warranted to evaluate potential effect of any chemical treatment in this rat strain. The high spontaneous incidence of LCTs in the testes of male F344 rats has made this tumor endpoint of little practical use in identifying potential testicular carcinogenic responses. TVM responses in F344 rats have a biological plausible relationship to LCTs unlike TVM in humans. Given their high spontaneous background incidence and species-specific biology, we contend that MNCL and LCT, along with TVM responses, in F344 rat carcinogenicity studies are inappropriate tumor types for human health risk assessment and lack relevance in predicting human carcinogenicity.

Abstract
OBJECTIVE To assess the colour Doppler and ultrasound features of testicular Leydig cell tumours (LCTs) in a population of 38 surgically proven lesions. METHODS From August 2008 to March 2015, we retrospectively included 38 surgically proven LCTs in 36 patients. Clinical data, scrotal colour Doppler, B-mode ultrasound and videos images were reviewed for each patient. The volume, echotexture of the testis, size, shape, echogenicity and the vascularization pattern of the lesion were evaluated. The tumour margins were categorized as either smooth or lobulated. The vascularization was classified as intense, moderate or without any hypervascularization. We defined the vascularization pattern groups as central, peripheral and mixed (the latter meaning both central and peripheral). RESULTS 26 patients were referred for infertility [5 patients were subsequently diagnosed with Klinefelter syndrome (KS) and 5 patients with cryptorchidism]. 28 patients underwent testis-sparing surgery, while 8 patients underwent a radical orchiectomy. The LCTs were mostly infracentimetric (68.4%), with a median size of 7.0 mm (ranging from 4.0 to 11 mm). 50% of the lesions had lobulated margins, and these were significantly larger than the smooth lesions (p < 0.05). The content of the lesions was markedly homogeneous and hypoechoic. All lesions had sharp demarcations from the adjacent pulp. 36/38 lesions exhibited moderate-to-intense hypervascularization, with a mixed intrinsic and peripheral rim pattern. Larger lesions were more hypervascularized (p < 0.05). LCTs in patients with KS had atypical features. CONCLUSION Typical sporadic LCTs appeared as isolated hypoechoic, infracentimetric masses, with a clear demarcation from the adjacent pulp. They presented intrinsic and peripheral rim hypervascularization. ADVANCES IN KNOWLEDGE By undertaking the largest imaging series of LCT to date (to our knowledge), we reassessed the typical sonographical aspects of LCTs, so as to provide guidance in regard to opting for testis-sparing surgery and for follow-up. LCTs present both intrinsic and rim vascularization detectable by colour Doppler ultrasound. Intrinsic vascularization and lobulated margins are common findings in testicular LCTs.

Abstract
We report a case of a small, intratesticular, incidentally identified, nonpalpable Leydig-cell tumor in which preoperative, dynamic, contrast-enhanced MRI was essential in characterizing the lesion as a neoplasm. Sonographic evaluation failed to demonstrate internal color Doppler flow, resulting in a differential diagnosis that included debris-filled cyst. At surgical resection, intraoperative ultrasound was essential to locate the mass and confirm complete removal. This case highlights the value of dynamic, contrast-enhanced MRI and intraoperative ultrasound for the management of incidental intratesticular lesions with indeterminate sonographic and Doppler characterization. Radiologists and urologists should be familiar with this approach to the incidental, sonographically indeterminate, nonpalpable intratesticular lesion identified on scrotal ultrasound.

Abstract
49,XXXXY pentasomy or Fraccaro's syndrome is the most severe variant of Klinefelter's syndrome (KS) affecting about 1/85000 male births. The classical presentation is the triad: mental retardation, hypergonadotropic hypogonadism and radio ulnar synostosis. Indeed, the reproductive function of Fraccaro's syndrome is distinguished from KS. Besides, Leydig cell tumors are described in cases of KS, but never documented in the Klinefelter variants.We describe a young adult of 22 years old who presented with hyper gonadotropic hypogonadism, delayed puberty and bilateral micro-cryptorchidism. Chromosomal pentasomy was confirmed since infancy. Bilateral orchidectomy revealed a unilateral well-circumscribed Leydig cell tumor associated with bilateral Leydig cell hyperplasia.Inspired from reporting the first case of Leydig cell tumor in a 49,XXXXY patient, we summarize the particularities of testicular function in 49,XXXXY from one side, and the risk and mechanisms of Leydig cell tumorigenesis in Klinefelter variants on the other side. The histological destructions in 49,XXXXY testes and hypogonadism are more profound than in Klinefelter patients, with early Sertoli, Leydig and germ cell destruction. Furthermore, the risk of Leydigioma development in KS and its variants remains a dilemma. We believe that the risk of Leydigioma is much higher in KS than the general population. By contrast, the risk could be lower in the Klinefelter variants with more than 3 supplementary X chromosomes, owing to an earlier and more profound destruction of Leydig cells rendering them irresponsive to chronic Luteinizing hormone (LH) stimulation.

Abstract
We present the sonographic and magnetic resonance imaging findings of Leydig cell tumors in a series of patients, along with a brief review of the literature. We evaluated the sonographic features of 11 cases of Leydig cell tumors, including echogenicity, size, margins, and patterns of vascularity. The magnetic resonance imaging characteristics of 9 patients were also assessed, with special attention to the appearance of the tumors on T2-weighted imaging and postcontrast T1-weighted imaging. Seven tumors were hypoechoic, and 4 were almost isoechoic. Ten patients showed various patterns of hypervascularity in the tumors, combined in some cases with feeding vessels. One case presented with a single feeding vessel. The tumors showed homogeneous or heterogeneous low signal intensity on T2-weighted imaging and marked enhancement on postcontrast T1-weighted imaging. The small size of these tumors, the various patterns of vascularity on color and power Doppler sonography, and the marked enhancement on postcontrast T1-weighted imaging are considered valuable but generally nonspecific for identification of these tumors.

Abstract
In order to explore the latest advances in organ-sparing treatment of testicular tumors, a literature search of the Medline/PubMed database was carried out for published data in the English language up to 2007. In the recent past the management of testicular tumors has evolved in favor of a testis-sparing approach in selected cases, both in the adult and pediatric population. The widespread use of high-frequency testicular ultrasound has led to detecting an increasing number of asymptomatic, non-palpable, small-volume masses. A higher proportion of testicular lesions of benign nature than previously reported has now been documented. The high accuracy of frozen section examination and the increasing interest in the potential functional, psychological and cosmetic advantages related to preserved testicular parenchyma are other arguments currently favoring the adoption of an organ-sparing policy for most testicular masses. Greater experience has been gained in also managing conservatively malignant tumors. Patients with germ-cell cancer in solitary testis or bilateral tumors can be submitted to testis-sparing surgery, provided that the maximum size of the lesion is <2 cm, preoperative testosterone is normal and adjuvant radiotherapy of the residual parenchyma is delivered. Cancer-specific survival is excellent, local recurrence rate very low and androgen supplementation unlikely.

Abstract
Ultrasound is a vital adjunct to clinical examination in diagnosing scrotal disease, as a number of different processes may present similarly. Potential applications range from the acute emergency to long-term screening as well as cases in which a distinct scrotal abnormality may or may not be palpable. Differentiating acute epididymitis/epididymoorchitis from testicular torsion is possible sonographically, thereby guiding appropriate medical or surgical management. Distinguishing between cystic, solid, or complex scrotal masses is readily performed with this modality. It clearly depicts simple versus complex hydroceles and determines the presence of underlying testicular or epididymal disease. Not only is ultrasound the best imaging modality for longitudinal screening in patients (testicular microlithiasis, cryptorchidism) at risk for testicular tumors, it also provides valuable information in the infertile male by documenting the presence or absence of a varicocele.

Abstract
PURPOSE Although most Leydig cell tumors are benign, radical orchiectomy is currently considered the standard therapy. We retrospectively analyzed the long-term followup of a series of patients with Leydig cell tumors electively treated with testis sparing surgery. MATERIALS AND METHODS Between November 1990 and December 2005, 17 consecutive patients with Leydig cell tumors underwent testis sparing surgery on an elective basis. Preoperative evaluation included physical examination, serum markers for germ cell tumors, scrotal ultrasound, abdominal computerized tomography, chest x-ray and hormonal profile if clinically required. Testis sparing surgery was performed via an inguinal approach with spermatic cord clamping. Frozen section examination was performed in all cases, revealing Leydig cell tumors. Followup consisted of physical examination, scrotal ultrasound, abdominal computerized tomography and chest x-ray every 6 months for the first 2 years, then annually. Tumor recurrence and survival were evaluated. RESULTS Mean patient age was 41.6 years (range 28 to 55). Medical referral was prompted by symptoms/signs such as infertility, gynecomastia or self-palpation of scrotal mass in 11 patients (64.7%), while in the remaining 6 (35.3%) the lesions were incidentally diagnosed. Hormonal profile was performed in 9 patients, showing abnormalities in all. Mean tumor diameter was 13.4 mm (range 5 to 31). Definitive pathological examination confirmed benign Leydig cell tumor in all cases. After a mean followup of 91 months (range 12 to 192), neither local recurrence nor distant metastases have been detected and all patients are alive without evidence of disease. CONCLUSIONS In patients with Leydig cell tumors testis sparing surgery with frozen section examination provides an excellent long-term oncological outcome.

Abstract
Leydig cell tumor (LCT) is a rare tumor of the male testicular interstitium. This article provides an overview of the major pathologic manifestations of LCT of the testis; patient characteristics; clinical, radiologic, and laboratory features; prognosis; and management. LCTs of the testis are frequently hormonally active, leading to either feminizing or virilizing syndromes. The tumor is usually benign, but malignant variants can occur. The pathologic diagnosis of LCT is usually made based on morphologic characteristics of the tumor cells. The significance of Reinke crystals in the diagnosis of LCT both cytologically and histologically is underscored. Pathologists have to be familiar with the diagnostic histopathologic features, immunohistochemical panel of this tumor, and its principal differential diagnoses to prevent tumor misdiagnosis.

PATIENTS AND METHODS Between September 2000 and April 2005, incidental intratesticular masses of < or = 5 mm in diameter were found in 20 men undergoing scrotal ultrasonography for reasons other than suspected testicular tumour. After staging, an organ-sparing approach including frozen-section analysis was used to obtain histological data. RESULTS The mean diameter of the detected tumour masses was 3.5 mm, and the mean (range) age of the patients was 36.4 (26-58) years. Four men (20%) had orchidectomy because the tumours were found to be malignant; the resected specimens yielded multifocal testicular intraepithelial neoplasia (TIN) in all patients and additional seminomatous tumour cells elsewhere in the testis in one. Frozen-section results were false-negative in one patient and he had orchidectomy after having established the definitive histological diagnosis. The 16 patients with benign lesions were correctly diagnosed and their testicles were not removed. CONCLUSIONS Advanced and innovative ultrasonography technology allows the detection of increasingly small testicular masses. In the present series, most incidental intratesticular lesions were benign. In patients with malignant lesions, multifocal TIN and/or distant seminomatous foci were present despite the tumour being small. Therefore, it is essential to perform exploratory surgery as it is the only way to obtain accurate histological findings, thus providing oncological efficacy and precluding removal of a testicle bearing a benign lesion.
