Giant Congenital Melanocytic Nevi: A Case Report and Review of Literature

Abstract

The congenital melanocytic nevi which are formed by the overgrowth of melanocytes occur in about 1% of the newborns. Giant Congenital Melanocytic Nevi (GCMN) which are of sizes larger than 20 cm diameter are rare and they occur in 1/500,000 newborns. Primary diagnosis of congenital giant nevus is clinical. Here, we report a case of full-term infant born with extensive black patch having smooth surfaces, irregular margins, and covering 45% of the skin surface.
