Gynecomastia in two young men with histories of prolonged use of anabolic androgenic steroids.

The aim of this report is to highlight the risk of anabolic androgenic steroid-induced gynecomastia in young men involved in nonagonistic sports and the role of ultrasonography in its diagnosis. The authors describe two cases of gynecomastia in nonprofessional weight lifters with histories of AAS use. In both cases, the diagnosis was based on patient history and clinical findings, but the sonographic examination confirmed the clinical suspicion and excluded the presence of other types of disease associated with mammary-gland enlargement in men.
