Mammary duct ectasia in children presenting bloody nipple discharge: A case in a pubertal girl

Abstract Mammary duct ectasia occurs rarely in childhood. The authors report on the case of a pubertal girl who was operated on for duct ectasia with bloody nipple discharge. Duct ectasia is regarded as a primary lesion; it is considered to be a cause of bloody secretion, and it has a mechanism similar to that of mammary duct papilloma. J Pediatr Surg 36:E2.
