[Spermatocytic seminoma. Report of 2 personal cases and review of the literature]

Abstract

The spermatocytic seminoma is a distinct testicular neoplasm with a low tendency to metastasize. Two own cases with the diagnosis of a spermatocytic seminoma are presented. A third patient is described, where the initial diagnosis of a spermatocytic seminoma was retrospectively changed to classical seminoma after developing retroperitoneal relapse during surveillance. A literature review revealed distinct histopathological characteristics and a remarkably good prognosis for spermatocytic seminoma. With only one case of relapse confirmed in the literature, in these patients postoperative treatment can safely be omitted in favor of surveillance. In case of spermatocytic seminoma diagnosis should be confirmed by a second pathologist.
