Abstract

Dermal dendritic melanocytic proliferations are a broad group of congenital and acquired melanocytic lesions characterized by the presence of dermal spindled and dendritic cells resembling melanocytes migrating from the neural crest to the epidermis. Historically, they were subdivided into dermal melanocytoses (naevus of Ota, Ito, Mongolian spot and related conditions), blue naevi and malignant blue naevi. The purpose of this review is to provide an update on recent developments in the field with emphasis on new entities and their differential diagnosis.
