Congenital Milium of the Nipple

Abstract

A 12-month-old girl presented with an asymptomatic, pearly nodule on the left nipple that had been present from birth and was currently 3 mm in diameter and growing. Assuming the diagnosis of congenital primary milium of the nipple, we took a "wait and see" approach. After 3 months, the pearl disappeared without any scarring.

Congenital Primary Milium on Nipple in a 3 Month Old Female Infant

“…Of note, we were able to find only 4 previous cases of 'primary milium on nipple in infant' and only 2 of them were congenital in onset (our case is third) [3].…”

“…These appear spontaneously and of note, spontaneous resolution of congenital forms may also occur mostly during the fourth week of life [2]. Congenital primary milia are seen to occur in up to 50% of full-term neonates, predominantly affecting nose, infraorbital and periocular skin [3]. Uncommonly, solitary larger milium may occur on the penis, scrotum, areola and vulva [2,3].…”

“…[3,4] Characteristic morphology and lamellated accumulation of keratins within cystic lumen on biopsy rule out all the above mentioned conditions [3,4].…”

“…To prevent such complications, complete excision or incision followed by manual expression of the contents should be done [3].…”
