Unusual case of classic testicular seminoma in a 90-year-old patient: a case report.

BACKGROUND Seminoma is the most common subtype of testicular cancer and occurs most commonly in patients aged 30-49 years, but decreases to a very low level in men in their 60s or older. CASE PRESENTATION A 90-year-old Syrian man with a 6-year history of an increase in size of his right scrotum, presented to the urological clinic and, on clinical examination, the findings suggested testicular tumor. After orchiectomy and histology results based on microscopic and immunohistochemical examinations, a pure seminoma was diagnosed, so we describe in this case report the second-oldest patient with classical seminoma in the medical literature. CONCLUSION This case report has been written to focus on the probability of any type of testicular tumor occurring at any age or decade; urologists should consider seminoma as a differential diagnosis with any testicular swelling even in elderly patients.
