title: [A case of spermatocytic seminoma].
abstract: In April, 1987, we treated a 33-year-old male patient who presented a painless swelling of the right scrotal content of 6 months duration. After surgery, the resected testis weighed 130 g, and the cut surface showed an edematous, white-yellow, homogenous tumor. A histopathological examination revealed a typical spermatocytic seminoma composed of three types of tumor cells. The small cells had pyknotic nuclei and an eosinophilic cytoplasm while the medium-sized cells and most of the giant cells had nuclei containing granular chromatins. Some of giant cells contained a filamentous, chromatin-like spireme of primary spermatocytes. A chest X-ray, CT scanning and lymphography revealed no metastatic lesions, and the patient is still alive with no evidence of disease 10 months after the orchiectomy.
