Congenital combined melanocytic nevus of the scalp with associated alopecia areata.
We report a case of a 20-year-old Chinese man with an alopecic congenital combined compound and blue melanocytic nevus of the scalp, associated with alopecia areata. The diagnosis of a combined melanocytic nevus was confirmed by histopathological examination and immunohistochemical stains, with exclusion of neurocristic hamartoma, which can have a similar clinical and histopathological appearance but different prognosis. In addition, we explore the association of this large melanocytic lesion with alopecia areata.
