Atypical maculopapular cutaneous mastocytosis showing a nevus spilus‐like lesion

摘要

Abstract A 13‐year‐old Korean girl presented with a 7‐year history of a pruritic, light‐brown patch containing multiple 0.2‐ to 0.5‐cm brownish‐to‐reddish maculopapules on the left anterior chest. When her skin was rubbed, the lesion became itchy and red. Histopathologic evaluation demonstrated marked dense dermal infiltration of mast cells. We report a rare case of atypical maculopapular cutaneous mastocytosis with clinical features similar to those of nevus spilus.
