[Large hepatic adenoma in a male patient].

Hepatic adenoma is a benign neoplasm found in women on oral contraceptives over long periods of time. Its incidence in men is lower, associated with androgen on anabolic steroid treatment, diabetes, storage diseases (glycogenosis type I and VI), barbiturates and clomiphene. We report a case of a man with a large hepatic adenoma without previous history of predisposing factors. The treatment was surgical because of the uncertain behaviour of this lesion.
