Upper gastrointestinal hemorrhage as a rare extragonadal presentation of seminoma of testis.

A rare case of a gastric presentation of a seminoma with burned out primary testicular tumor is described. The patient initially presented with upper gastrointestinal hemorrhage. Endoscopic biopsies were suggestive of seminoma, and testicular ultrasound revealed a focal lesion and testicular microcalcification. Treatment consisted of bilateral orchidectomy, followed by four cycles of etoposide and bleomycin, where a complete response was achieved. Testicular histology was consistent with the "burned out" phenomenon and no tumor cells were found. There are only two previously reported cases of extragonadal seminoma in the stomach.
