title: Halo scalp ring with purulent drainage in a newborn.
abstract: We present the case of a 2-week-old male infant who repeatedly presented to the pediatric emergency department for fussiness and drainage from a head wound. The infant had an ultimate diagnosis of halo scalp ring, a rare dermatologic condition that is treated conservatively. This condition shares characteristics with infectious processes and must be differentiated from more serious illness to minimize unnecessary and expensive medical treatment.
