We report 22 cases of prepubertal gynecomastia diagnosed during growth hormone (GH) treatment. The age and dose range were 2 to 12 years and 0.18 [corrected] to 0.3 mg/kg per week, respectively. In most of the patients, gynecomastia appeared between 0.5 and 7 months after GH was started. Three boys were using drugs other than GH. This condition appears to be self-limited and benign.
