A case of primary extragonadal seminoma arising in the perineum

We report the first case of primary extragonadal seminoma arising in the perineum. A 34-year-old-man presented with a 2-cm painless mass in the perineum. He underwent surgical resection, and histology showed poorly differentiated adenocarcinoma. Three months later, local recurrence occurred. Whole evaluation including ultrasound and MRI of the testes were normal, so he underwent surgical wide excision, and pathology showed the tumor was pure seminoma. He received two courses of bleomycin, etoposide and cisplatin (BEP) therapy, and there has been no evidence of recurrence for 1 month. Copyright (c) 2006 S. Karger AG, Basel.
