32795 The neonatal “blueberry muffin rash” – Act fast and get tissue

Abstract

A 6-day-old, full-term female, with no prenatal complications and an unremarkable delivery, presented with 2 purplish, brown, asymptomatic bumps since birth. She was otherwise well, breast feeding, and gaining weight appropriately. On examination, there were two 1-cm, well-demarcated, firm, violaceous nodules on her abdomen and right forearm, with dermoscopy showing homogenous brown discoloration. No lymphadenopathy, hepatosplenomegaly, alopecia, or other rash was noted. Punch biopsy revealed an unremarkable epidermis.
