title: Benign galactorrhea/breast discharge in adolescent males probably due to breast self-manipulation.
abstract: Three adolescent males presented with nipple discharge. In two boys, the expressed secretion was clinically consistent with galactorrhea. Galactorrhea/breast discharge is a rare complaint in males of any age. Although galactorrhea is commonly associated with a neuroendocrine disorder or drug ingestion, the work-up in each, including basal prolactin level, was normal. Reluctantly, each by admitted to breast self-manipulation to reduce gynecomastia. When the behavior was discontinued, the galactorrhea/breast secretion ceased. Clinicians should be aware of this heretofore undescribed and apparently benign phenomenon. If basal hyperprolactinemia is absent in a male with a breast discharge and a history of breast manipulation, then an extensive work-up is not usually indicated.
