Dermal melanocytosis includes several benign pigmented lesions which present as blue-gray color which is a result of the color transmission of melanin pigment through the dermis. While some types are present at birth, there is an acquired variant, acquired dermal melanocytosis (ADM), which usually involves faces of middle-aged Asian women. To the best of our knowledge, there are limited reports of extra facial ADM which all are on the trunk and extremities. Herein, we report a unique case of extra facial ADM affecting the scalp of a middle-aged man and provide a review of all extra facial ADM cases that have been reported.
皮肤黑素细胞增多症包括几种良性色素沉着性病变，表现为蓝灰色，这是黑色素通过真皮层透射颜色的结果。虽然有些类型在出生时就存在，但有一种后天性变体，即后天性皮肤黑素细胞增多症（ADM），通常累及中年亚洲女性的面部。据我们所知，关于面部以外ADM的报道有限，且均位于躯干和四肢。在此，我们报告一例累及中年男性头皮的面部以外ADM的独特病例，并对已报道的所有面部以外ADM病例进行综述。
