Gynecomastia consists of breast enlargement due to a hormonal imbalance between estrogens and androgens. Unilateral and important breast growth requires ruling underlying pathologic disorders out. Mechanical cause is uncommon, causing enlargement by repeated stimulation. We report a 6-year-old boy with unilateral gynecomastia. Hyperprolactinemia is the only abnormal finding at laboratory tests. After repeated inquiries, a continuous breast selfstimulation is detected. Its relation with gynecomastia is verified because prolactin normalizes and breast regressed in further revisions, after stopping stimulus.
男性乳房肥大是由于雌激素和雄激素之间的激素失衡导致乳房增大。单侧且明显的乳房增大需要排除潜在的病理疾病。机械性原因并不常见，通过反复刺激导致乳房增大。我们报告一名6岁单侧男性乳房肥大患儿。实验室检查仅发现高催乳素血症这一异常结果。经过反复询问，发现患儿存在持续的乳房自我刺激行为。由于在停止刺激后，进一步复查时催乳素水平恢复正常且乳房消退，从而证实了其与男性乳房肥大的关系。
