[Late metastasis of an extragonadal Leydig cell tumor]. / Spät-Metastasierung eines extragonadalen Leydig-Zelltumors.

The case of a 36-year-old patient who underwent extirpation of a Leydig cell tumor of the epididymis is presented. Five years later a retroperitoneal mass was removed, which was found to be a metastatic Leydig cell carcinoma. The literature conrains reports of only 32 cases of metastatic Leydig cell tumors, all of which had originated in the testis and not extragonadally. The symptoms, treatment and prognosis are discussed with reference to the literature.
