Spermatocytic seminoma (SS) is a rare testicular neoplasm characterized by a palpable, painless, slowly enlarging mass in the testis. Even more rare is a synchronous bilateral presentation. Only eight cases of bilateral SS have been reported in the literature, of which three cases were present with synchronous testis enlargement, and five were sequential. Here, we report an additional case of s...

Neonatal testicular tumors are rare and should be considered in the differential diagnosis of newborn scrotal masses. Juvenile granulosa cell tumor (JGCT) accounts for about 5% of all prepubertal testis tumors. As a benign neoplasm, radical orchiectomy is sufficient for treatment. We report a case of a newborn with a prenatal diagnosis of scrotal mass. After surgery, the histological diagnosis ...

Adenocarcinoma of prostate metastasizing to testis is a rare occurrence and is incidentally detected in orchiectomy specimens. The pattern of metastasis may mimic a primary neoplasm of testis like a seminoma or lymphoma and pose a diagnostic difficulty for the pathologist. A rare case of bilateral testicular metastasis of prostatic adenocarcinoma is presented wherein the metastatic cells expres...

We present a case of necrotizing vasculitis with the testicle as the isolated affected organ. A 25-year-old man, pretreated for epididymo-orchitis, presented with a presumed testicular neoplasm. Radical orchiectomy was performed and diagnosis of necrotizing vasculitis was established. In the absence of any other sign of systemic disease, the diagnosis of isolated necrotizing vasculitis of the t...

Papillary intralymphatic angioendothelioma is a rare, low-grade neoplasm of lymphatic channels that usually presents intradermally or subcutaneously. We report the case of a 24-year-old male presenting with an isolated intratesticular palpable mass and symptoms of testicular pain. Preoperative ultrasound examination showed an irregular, heterogeneous mass. Subsequent surgery and pathologic asse...

Testicular cancer has become a model for a curable neoplasm, where biochemical markers play a critical role. Serum tumor markers are integral in patient management and contributes to the diagnosis, staging, and risk assessment, as well as evaluation of response to therapy and detection of relapse. We review their biochemistry, biology, and clinical use in the setting of localized and metastatic...

BACKGROUND Primary testicular lymphoma is a unique, rare and aggressive extra nodal non-Hodgkins Lymphoma (NHL). It is the most common testicular tumour in males between 60 and 80 years old OBJECTIVE To report a case of primary testicular lymphoma in a young man who has done very well on surgery and chemotherapy. METHODS The patient a Nigerian male civil servant who was single and aged 31 y...

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 ...

Introduction: Splenogonadal fusion is a rare congenital anomaly characterized with anomalous fusion of the spleen and the gonad or mesonephric derivatives. Herein, we report the case of a 7-month-old boy with unusual presentation of splenogonadal fusion. Case Presentation</...

BACKGROUND The study of neoplasia in wildlife species contributes to the understanding of cancer biology, management practices, and comparative pathology. Higher frequencies of neoplasms among captive non-domestic felids have been reported most commonly in aging individuals. However, testicular tumours have rarely been reported. This report describes a metastatic testicular sex cord-stromal tum...
