Androblastoma and germ cell tumor of the same testis: a case report.

The rare case of a testicular androblastoma associated with a complex germ cell tumor of the same testis is reported. Gynecomastia preceded the clinical appearace of testicular swelling by 3 months, suggesting that the 2 tumors developed contemporaneously and that, in theory, the Sertoli cell tumor is probably dependent on the germ cell tumor.
