Congenital mucinous eccrine nevus in a 5-month-old girl with frequent intertriginous dermatitis.

We present a 5-month-old girl with one localized plaque in a bandlike distribution on the left wrist since birth. Localized hyperhidrosis was also noted. Histopathologic examination of the lesion showed typical findings of mucinous eccrine nevus. Our report may serve to alert dermatologists to consider this entity in congenital lesions.
