Multiple eruptive milia.

Multiple eruptive milia (MEM) is a rare skin condition characterized by sudden onset of multiple milia occurring mainly on the head, neck, and trunk. Milia are small, benign, 1- to 4-mm, white keratinous cysts. The lesions generally are asymptomatic and may arise spontaneously or secondary to a number of processes. Multiple eruptive milia are cosmetically troublesome and difficult to treat. We report the case of a 40-year-old man with an abrupt onset of MEM on the face.
