Abstract:
Ten years after his brother had been treated for seminoma, a 36-year-old male presented with a giant exulcerating mass involving the right testis and both inguinal regions. Subsequent biopsy revealed pure seminoma. Staging computed tomography (CT) showed bulky retroperitoneal and pelvic lymph node metastases. After seven courses of cisplatin-based chemotherapy, positron emission tomography suggested residual tumor in the right groin. The suspicious lesion and the right testis were resected showing no vital tumor tissue. Eight months after surgery there were no signs of disease progression at follow-up CT.
