We report the first patient with a nipple adenoma presenting in infancy. Nipple adenoma is a benign lesion typically affecting women between 45 and 55 years of age. This lesion can occur in the pediatric population and should be included in the differential diagnosis of an infantile breast lesion. Management of children with nipple adenoma requires consideration for breast development; excision before maturity may cause nipple-areola deformity or injury to the breast bud.
