Abstract

Dermal melanocytosis is a common pigmented skin disease, characterized by an increased number of ectopic melanocytes in the dermis. Rare variants of dermal melanocytosis that do not belong to these four typical groups-nevus of Ota, nevus of Ito, blue nevus, and Mongolian spots-are called dermal melanocyte hamartoma, or congenital dermal melanocytosis (CDM) as it mostly appears from birth. We report a case of CDM on the foot of a young woman with a literature review of previously reported cases of CDM.
