title: Metachronous bilateral leydig cell tumor in a male adult aged 20.
abstract: We report a young male aged 20 who has suffered two episodes of Leydig cell tumor of the testis, the second occurring 5 years after the first in the contralateral testis. The case is outlined briefly, with references taken from the literature. This young man's history is exceptional as this type of tumor is infrequent, and metachronous bilateral presentation extremely rare.
