Intraduct papillomatosis of the breast in a peripubertal male.
A 13-year-old boy presented with right-sided gynecomastia. Histological examination of the excised specimen revealed distention of ducts by papillary configurations of proliferating epithelium. The boy had no known family history of breast disease and physical examination revealed minor dysmorphic features, but a karyotype was normal. The possible relationship of this lesion to other proliferative lesions described in the pubertal male breast is discussed.
