Atypical clinical features may mimic impetigo, Langerhans cell histiocytosis, and carcinoid syndrome; however, only 1 case of scarring alopecia associated with mastocytosis has been reported. We present the first case of cutaneous mastocytosis associated with congenital alopecia areata in a 3-year-old Korean girl. This case showed an atypical clinical presentation of congenital alopecia areata, but histopathological results confirmed the diagnosis of cutaneous mastocytosis.
