We report a case of extragonadal seminoma presenting as a polypoid mass in the urinary bladder. The patient presented with two months history of hematuria. Evaluation by CT scan and cystoscopic examination revealed a polypoid mass in the base of the bladder. Biopsy of the mass revealed a classical type of seminoma. The diagnosis of seminoma was supported by strong immunostaining of the tumor cells for C-Kit and placental alkaline phosphatase. Thorough physical examination and radiologic imaging of other organ systems failed to reveal any other tumor. Both testes were found to be normal on examination and on ultrasound imaging. Patient responded well to chemotherapy. This case is unique because to the best of our knowledge there are no previously reported cases in the literature with seminoma presenting as a bladder mass.

Primary retroperitoneal seminoma is an exceedingly rare type of germ cell tumor, accounting for less than 5% of all such tumors. These tumors are typically large at presentation due to their slow growth and the nonspecific nature of symptoms, which often leads to delayed diagnosis. A 40-year-old male presented with intermittent abdominal pain and a palpable lump in the right paraumbilical region.

Testicular cancer is one of the leading malignancies affecting young men, with germ cell tumors (GCTs) being the most prevalent type. These tumors are classified into two main subtypes: seminomas and non-seminomatous germ cell tumors (NSGCTs), with the latter known for their higher likelihood of metastasis. Early detection through imaging and tumor markers like alpha-fetoprotein (AFP) and beta-human chorionic gonadotropin (HCG) is crucial for favorable outcomes.

We report the case of a 39-year-old patient who complains about loss of libido and erectile dysfunction. Hormonal diagnosis revealed hypergonadotropic hypogonadism suggesting a primitive testicular cause. Testicular examination, testicular ultrasounds and abdomen-pelvis CT scan made it possible to suspect a right testicular tumor.
