Sex cord-stromal tumors (SCSTs) are the second most frequent category of testicular neoplasms, accounting for approximately 2-5% of cases. Both genetic and epigenetic factors account for the differences in frequency and histologic composition between testicular and ovarian SCSTs. For example, large cell calcifying Sertoli cell tumor and intratubular large cell hyalinizing Sertoli cell neoplasia occur in the testis but have not been described in the ovary. In this article, we discuss recently described diagnostic entities as well as inconsistencies in nomenclature used in the recent World Health Organization classifications of SCSTs in the testis and ovary...

Spermatocytic tumor, formerly known as spermatocytic seminoma, is an uncommon testicular neoplasm which is a distinct clinicopathologic entity from classic seminoma. These tumors are not associated with germ cell neoplasia in situ, other germ cell tumors, or isochromosome 12p. Although typically, these tumors have an excellent prognosis occasional cases are associated with sarcoma and have a very poor prognosis. We present a case of spermatocytic tumor with sarcoma showing a chondrosarcomatous component, discuss the pathologic findings and differential diagnosis and provide follow-up information...

BACKGROUND: Testicular cancer is the most common male neoplasm occurring in men between the ages of 20 and 34. Although germ-line testicular tumors respond favorably to current standard of care, testicular stromal cell (TSC) tumors derived from Sertoli cells or Leydig cells often fail to respond to chemotherapy or radiation therapy and have a 5-year overall survival significantly lower than the more common and more treatable germ line testicular tumors. METHODS: To improve outcomes for TSC cancer, we have developed a therapeutic vaccine targeting inhibin-α, a protein produced by normal Sertoli and Leydig cells of the testes and expressed in the majority of TSC tumors...

INTRODUCTION: Leydig cell tumor constitutes only about 1-3% of testicular neoplasms. There is apparently increased incidence in the last few years; one possible explanation for this phenomenon is the widespread use of ultrasound technology and the subsequent increased early detection of smaller lesions that have not been found in historical series. CASE PRESENTATION: We report a case of Leydig cell tumor of testis in a patient presenting with painless long standing slowly growing left scrotal mass who found to have intrapulmonary nodule and multiple enlarged retroperitoneal lymph nodes on staging work up...

Thymoma is the most common neoplasm of the anterior mediastinum and has malignant potential. Germ cell tumors (GCTs) found in the anterior mediastinum are usually benign, and malignant GCTs, such as seminomas, are rare. Histologically, mediastinal seminoma is indistinguishable from testicular seminoma except for site-associated morphological features such as lymphoid follicular hyperplasia. Therefore, excluding metastasis is very important. Recently, we treated a young adult patient with multiple thymic masses that occurred simultaneously...

Testicular germ cell tumors (TGCT) are a group of heterogeneous, biologically diverse and clinically challenging neoplasms. Despite the relatively low incidence and mortality rates, a subgroup of patients with disseminated disease relapse after conventional therapy and have a dismal prognosis. Moreover, TGCT afflict mostly young men and have therapeutic peculiarities, with some patients showing resistance to cisplatin-based treatments and others being troubled by irreversible side effects, such as infertility...

INTRODUCTION: Testicular benign tumors are very rare (< 5%). Testicular Angiofibroma (AF) is one of those, however the gold standard of treatment and follow-up is still unclear. CASE REPORT: A 47 years-old man with only one functioning testis was referred to our clinic for a palpable right testicular mass and atrophic contralateral testis. Patient underwent testis-sparing surgery with inguinal approach and intraoperative frozen sections examination with diagnosis of AF...

BACKGROUND: Neuroendocine carcinoma of the gynecologic tract is rare and poses a significant clinical challenge because of tumor heterogeneity and lack of standardized guidelines for treatment. Ovotestis refers to the histology of a gonad that contains both ovarian follicles and testicular tubular elements. Ovotesticular disorder of sexual development occurs in fewer than 10% of all disorders of sexual development. Gonadal tumors with malignant potential occur in 2.6% of all cases of ovotesticular disorder of sexual development...

BACKGROUND: The optimal treatment strategy for patients with clinical stage I (CS-1) seminoma is controversial. The objective of the current study was to evaluate the outcomes for patients considered to be at high risk of disease recurrence with a tumor size ≥6 cm. Patients were treated with either adjuvant radiotherapy (RT) or followed with surveillance. METHODS: From the Danish Testicular Cancer database, the authors identified 473 patients with CS-1 seminoma with a tumor size ≥6 cm...

Peutz-Jeghers Syndrome (PJS) is inherited as an autosomal dominant trait which is characterized by multiple gastrointestinal hamartomatous polyps, mucocutaneous pigmentation, and an increased risk of neoplasm. Large Cell Calcifying Sertoli Cell Tumor (LCCSCT) is a kind of sex cord-stromal tumor, often bilateral and multifocal, accounting for 0.4 -1.5% of entire testicular tumors which may co-exist with PJS and is characterized radiologically by calcification foci within the testes. Surgical treatment options for this tumor range from testis-preserving surgery to radical orchiectomy...

Testicular cancer represents the most common malignancy in males aged 15-34 years and is considered a model of curable neoplasm. Maintaining success, reducing treatment burden, and focusing on survivorship are then key objectives. Inguinal orchiectomy is the first recommended maneuver that has both diagnostic and therapeutic aims. Most patients are diagnosed with stage I disease (confined to the testicle). Close surveillance and selective, short-course adjuvant chemotherapy are accepted alternatives for these cases...

The World Health Organization (WHO) released a new tumour classification for the genitourinary system in early 2016 after consensus by pathologists with expertise in these organs. It utilized the framework of the 2004 classification, and incorporated the most up-to-date information concerning these tumours. In testicular tumours, the majority of the changes occurred in the nomenclature and classification of germ cell tumours; however, several modifications were also made for non-germ cell tumours. Among sex cord-stromal tumours, sclerosing Sertoli cell tumour (SCT) is no longer recognized as a separate entity but as a morphological variant of SCT not otherwise specified (NOS), as CTNNB1 gene mutations have been noted in both neoplasms but not in the other forms of SCT...

Benign testicular teratomas are always thought to be pediatric neoplasms and previously all the teratoid tumors in the adult testis regarded as malignant. Recently, three publications reported benign testicular teratomas in adulthood and the latest WHO classification refers them as "prepubertal type of teratomas" which rarely appear in adulthood. These neoplasms behave benign and seemingly analogous independently whether they appear in pre- or postpubertal patients. The aim of our study was to investigate the frequency of benign testicular teratomas both in children and adults...

From the 1940s through 1977, at least 590,000kg of polychlorinated biphenyls (PCBs) were released into the Hudson River from General Electric manufacturing plants located in Hudson Falls and Fort Edward, New York. In 1984, the U.S. Environmental Protection Agency designated a nearly 322km reach as the Hudson River PCBs Superfund Site. Here we describe a Fish Health Assessment study, part of a Natural Resource Damage Assessment, that evaluated the prevalence of toxicopathic lesions in adult brown bullhead (Ameiurus nebulosus), smallmouth bass (Micropterus dolomieu), and yellow perch (Perca flavescens)...

Ultrasonography (US) has a fundamental role in the initial examination of patients who present with symptoms indicating abnormalities of the inguinal canal (IC), an area known for its complex anatomy. A thorough understanding of the embryologic and imaging characteristics of the contents of the IC is essential for any general radiologist. Moreover, an awareness of the various pathologic conditions that can affect IC structures is crucial to preventing misdiagnoses and ensuring optimal patient care. Early detection of IC abnormalities can reduce the risk of morbidity and mortality and facilitate proper treatment...

Importance: Patients given systemic treatment for testicular germ cell cancer (GCC) are at increased risk for a second malignant neoplasm (SMN). Previous studies on SMN and causes of death lacked information on the exact treatment applied or were based on patients receiving former treatment options. Objective: To evaluate the treatment-specific risks for SMN and death in a nationwide population-based cohort of patients with GCC treated with current standard regimens...

INTRODUCTION: Testicular cancer is one of the most frequent in young men and its incidence is increasing in recent years because of incidental finding during routine ultrasound exams. Adenomatous hyperplasia of the rete testis is one of the benign and rare pathological types incidentally detected and very few cases are described in the literature. CASE REPORT: A 40 years old man come to our attention for a balanoposthitis without testicular pain. During andrological examination we performed palpation of the testes and we noticed a palpable nodule of hard consistency in the left testicle...

Primary mediastinal germ cell tumors are uncommon tumors that can pose diagnostic difficulties due to their morphologic spectrum and unusual site. Immunohistochemistry plays an increasing role in the diagnosis of these tumors. Whereas the immunophenotype of testicular yolk sac tumors (YST) is rather well known, the opposite is true for primary mediastinal YST leading us to investigate the immunohistochemical features of 14 such neoplasms. Fourteen cases of primary mediastinal YST were reviewed and representative whole tissue sections were selected for immunohistochemical analysis using antibodies directed against CAM5...
