Dynamic evolution of a scalp congenital melanocytic nevus with poliosis and cutis verticis gyrata.

Cutis verticis gyrata (CVG), characterized by cerebriform overgrowth of the scalp, is rarely observed in congenital melanocytic nevi (CMN). We describe a 13-year-old male with autism and a large CMN of the scalp with numerous satellite nevi whose scalp nevus exhibited evolution with poliosis and CVG. Given the potential association of CVG (independent of CMN) with seizures, neuropsychiatric, and ophthalmologic disorders, and nevus-associated CVG (cerebriform intradermal nevus) with melanoma, multidisciplinary evaluation of CMN patients with CVG is important to guide management and treatment.
