Coexistence of bilateral seminomas and adenomatoid tumor is rare. We encountered an interesting case of bilateral testicular seminomas along with a paratesticular nodule which was diagnosed as an adenomatoid tumor on histology. Although seminomas and adenomatoid tumor are frequent neoplasms, bilaterality and their coexistence have been rarely described and can pose diagnostic difficulties. Herein, we describe a case of a 53-year-old man who presented with bilateral testicular swellings which were diagnosed as bilateral seminomas with an adenomatoid tumor in the left paratesticular region on histopathology...

Testicular Sertoli cell tumors (SCT) are rare and most fall into the category of SCT-not otherwise specified (SCT-NOS). Only a few additional types of SCT are recognized. Sclerosing SCT (S-SCT), originally described in 1991, comprises a small fraction of SCTs and was considered a specific entity until the 2016 revision of the World Health Organization classification of non-germ cell tumors, where it was classified as a morphologic variant of SCT-NOS. In a recent study, differences in expression of PAX2/PAX8, inhibin, androgen receptor and S100 protein between SCT-NOS and S-SCT were noted in a small number of cases...

Primary signet ring stromal tumor of the testis (PSRSTT) is an extremely rare tumor described only twice in the literature. Pancreatic-analogue solid pseudopapillary neoplasm (SPN) of the testis is a recently reported entity with morphological overlap with PSRSTT. We reviewed our files to find all cases of PSRSTT in order to better characterize this entity. We studied 13 cases of PSRSTTs using histological, immunohistochemical (IHC) and molecular genetic methods and compared the results with pancreatic SPN...

INTRODUCTION: Testicular seminoma affects relatively young men with excellent survival outcomes. There has been increasing concern that radiotherapy (RT) leads to secondary malignant neoplasms (SMNs) and subsequent mortality. We evaluated the effect of RT on incidence of SMNs and quantified cancer-related mortality and other causes of death for patients with stage I and II testicular seminoma. MATERIAL AND METHODS: A national sample of men (1988-2013) diagnosed with stage IA/IB/IS/IIA/IIB/IIC testicular seminomas from Surveillance, Epidemiology, and End Results were evaluated...

Carney complex is a rare genetic disease characterised by a complex of myxomas, spotty pigmentation and endocrine overactivity. At diagnosis, about one-third of male patients presents with testicular tumours, namely large cell calcifying Sertoli cell tumours, which are often multicentric and/or bilateral and have a low malignant potential. Although radical orchiectomy is the gold standard for the treatment of testicular neoplasms, a conservative approach with partial orchiectomy or tumourectomy may be the best treatment option for these patients, allowing the preservation of endocrine function, fertility and body image...

Leydig cell tumors (LCTs) are rare testicular tumors. Incidence is 1%-3% of all testicular neoplasms, bilateral in 10%. They are frequently hormonally active, leading to feminizing or virilizing syndromes. LCTs can be either pure or mixed with germ cell tumors or other sex cord-stromal tumors. Here, we are reporting a benign pure LCT in a 6-year-old boy presented with pseudopuberty.

Extraskeletal osteosarcomas (OSs) are highly malignant soft tissue tumours associated with a poor prognosis. Only a few records of these rare aggressive neoplasms have been reported in the literature.We describe the case of a 49-year-old man, who presented to our tertiary care centre with a painful isolated lump around the umbilicus. After surgical biopsy, imaging and subsequent pathological analysis, the swelling was diagnosed to be a localised extraskeletal OS. He received previous radiation as treatment for testicular seminoma 40 years ago, which has been in remission ever since...

GATA-3 expression in testicular/gynecologic mesothelial neoplasms and benign mesothelia have not been completely investigated. We graded GATA-3, calretinin, and WT1 staining in 20 adenomatoid tumors [9/20 (para)testicular and 11/20 tubal/uterine] and 38 normal mesothelia (20/38 tunica vaginalis and 18/38 fallopian tubes) as either 0 (≤5%), +1 (>5% and <25%), +2 (≥25% and ≤50%), and +3 (>50%). Adenomatoid tumor GATA-3 staining: 2 urologic cases were positive (2/9, +3 and +1), no gynecologic cases were positive (0/11), and all were positive for WT1/calretinin (20/20,+2 to +3)...

AIMS: Low-grade serous neoplasms of the testis are rare neoplasms that show striking morphological similarities with the better-understood ovarian neoplasms. This study is to see if there are similar molecular abnormalities in these two tumours. The cell of origin, relationship with serous ovarian tumour and the pathogenesis of these neoplasms are not fully established. METHODS AND RESULTS: As low-grade serous ovarian neoplasms are known to harbour mutations in the MAPK pathway, we investigated the involvement of BRAF and KRAS mutations in low-grade testicular serous tumour by performing mutational analysis of seven cases...

Burned-out testicular tumor is a very rare clinical entity. There is no clinical finding in the testicle because it regresses spontaneously without any treatment and generally presents with metastases. Clinical examination of the testis and scrotal sonography are pivotal in the initial diagnosis of such neoplasms. We present a case of a 22-year-old male with hemoptysis, weight loss, and abdominal pain for the past 2 weeks and no palpable lesion on testicular examination. No relevant past medical history.

INTRODUCTION: The palliative effects of cannabis sativa (marijuana), which include appetite stimulation, attenuation of nausea and emesis, and pain relief, are well known. The active components of cannabis sativa (cannabinoids) and their derivatives have received growing interest due to their diverse pharmacological activities, such as cell growth inhibition and tumour regression. The aim of this review is to look at the current evidence on the antiproliferative effects of cannabinoids in urological malignancies, including renal, prostate, bladder, and testicular cancers...

The paratestis (PT) is defined by the testicular tunics, epididymis, spermatic cord, rete testis, and embryonic remnants. It gives rise to a large diversity of pathologies, including those of soft tissue, which may prompt orchiectomy. We performed a 17-year search of our database for orchiectomies for a PT soft-tissue mass. In a total of 4741 orchiectomy specimens, 138 orchiectomies were performed for primary neoplastic or nonneoplastic masses of the PT soft tissue or had an incidental PT soft-tissue mass. Of these, 65...

Sex cord-stromal tumors (SCSTs) are the second most frequent category of testicular neoplasms, accounting for approximately 2% to 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...
