title: Leydig cell tumor of testis with adipose metaplasia.
abstract: A Leydig cell tumor of testis was discovered during evaluation of infertility in a 36-year-old white man with azoospermia and high plasma estrogen level. Histological examination revealed multiple foci of calcification and massive adipose metaplasia. This is the first time that adipous metaplasia is observed in association with Leydig cell tumor of testis.
