title: Extragonadal sacrococcygeal seminoma--a case report.
abstract: We report herein, a rare case of a 32 year old man who presented with a massive sacrococcygeal tumor found by digital examination. A transrectal biopsy was performed, however, as massive anal bleeding occurred 1 day later, an abdominal perineal resection was carried out. Histologic examination subsequently revealed the giant tumor to be pure seminoma. Residual masses of seminoma were detected by CT examination 1 month postoperatively and, despite irradiation, the patient died 26 months after the operation. Although there have been reports of extragonadal seminoma being located in the retroperitoneum, mediastinum and pineal body, this is the first reported case of it being found in the sacrococcygeal region.
