A Case of Congenital Lobulated Intradermal Nevus / 대한피부과학회지

ABSTRACT

Lobulated intradermal nevus is a rare subtype which has distinct clinicopathological findings and is similar to a regressing melanocytic nevus. A 22-year-old female presented with a lobulated 6.5 x 8.5 cm sized black plaque on her right shoulder. This had been present since birth and had grown slowly with a darkening change in colour. A skin biopsy revealed a fatty infiltration within the nest of nevus cells, dermal fibrosis and neuroid differentiation of the nevus cells.
