[A case of seminoma with epididymal swelling].

A 36-year-old man noticed a discomfort in the right scrotum since January, 1981, and came to our hospital in October of the same year. Palpation detected a hard and painless tumor in the right epididymal tail and exploratory excision revealed an induration measuring 3 X 2 X 1 cm. The rapid diagnosis of tumors by frozen section was made and we diagnosed it as right epididymal seminoma. Right high inguinal orchiectomy was performed and histopathologically, tumor cells which mainly occupied the testis were observed. This case was diagnosed as seminoma which showed epididymal swelling as the clinical symptom.
