Bloody nipple discharge in an infant and a proposed diagnostic approach

Bloody nipple discharge is a rare finding in infants and is associated most often with benign mammary duct ectasia. The rarity of this symptom in infants and its association with breast carcinoma in adults can lead to unnecessary investigation and treatment. Here we describe a 4-month-old boy with bilateral bloody nipple discharge that resolved spontaneously without treatment by 6 months of age. Furthermore, we propose a strategic method for the evaluation of such infants. KEY WORDS. Key Words: blood, breast/pathology, breast/ secretion, breast/surgery, breast neoplasms, infant, mammary duct ectasia, mastectomy, nipples/secretion.
