Testicular choriocarcinoma metastatic to skin and multiple organs. Two case reports and review of literature.

Two cases of males with subcutaneous masses as the first clinical sign of testicular choriocarcinoma are reported. The urine and serum human chorionic gonadotropin (hCG) test confirmed high level hCG from male choriocarcinoma. These cases, although very rare, can be a great diagnostic and therapeutic challenge and should be considered in the differential diagnosis of subcutaneous masses occurring in young males.
