Case report Pointillist melanotic macules: a new clinical entity?

Abstract

A Chinese male and his father both presented disseminated, variably-sized and pigmented spots as well as stellate macules in their adulthood. No signs indicated a systemic involvement after extensive evaluation. Skin examina tion revealed that most macules were stellate or claw-like that differ from each other in shape and size. However, as a whole, these discrete lesions were interspersed regularly. Pathological changes included remarkable basilar lay er hyperpigmentation (black eye line sign) without proliferation of the melanocytes. Melanophages were noted in the dermis. We proposed the diagnosis of pointillist melanotic macules, and believe this is a new clinical entity.
