According to the newest WHO classification tumors of the testis are divided into germ cell tumors derived from germ cell neoplasia in situ, germ cell tumors unrelated to germ cell neoplasia in situ, sex cord-stromal tumors, tumors containing both germ cell and sex cord-stromal elements, haematolymphoid tumors, and other rare tumors of the testis. Spermatocytic tumor is a rare neoplasm that occurs mainly in adults and is part of germ cell tumors unrelated to germ cell neoplasia in situ. Three cell populations without prominent lymphocytic nor granulomatous stromal reaction can be seen histologically.These tumors are negative for most usually used germ cell tumors immunohystochemical markers with the exception of CD117, which can be positive in about 40% of the cases. In the time of diagnosis or writing this report our patient had spermatocytic tumor without known metastases. Follow-up was ten months.
