[Spermatocytic seminoma. Apropos of 4 cases].

The records of 4 patients treated for a spermatocytic seminoma between 1974 and 1993 were reviewed. We described pathological and clinical features of this entity of seminoma which differs from those of classic seminoma. Spermatocytic seminoma is an essentially non metastasizing neoplasm unless complicated by the rare development of a sarcomatous component or metastatic spread.
