Seminoma metastasized to the prostate: A case report and literature review

The testicular seminomas are germ-cell tumors which account for approximately 50% of all testicular tumors. Most primary testicular germ cell tumors metastasize through a lymphatic system in a predictable pattern with the retroperitoneal lymph nodes being the most common initial metastatic site. Hematological metastasis to the distant organs is less common, and except for pulmonary metastasis, changes the classification from good to intermediate prognosis. Metastasis of testicular seminoma to the prostate is an extremely rare entity with only five reported cases in the literature. In this report, we present a 63-year-old male with recurrent testicular seminoma presenting in prostate.
