An Unusual Presentation of Neurotized Congenital Giant Melanocytic Nevus and Type 1 Neurofibromatosis: A Diagnostic Challenge
Main Article Content
Abstract
Among the three subtypes of neurofibromatosis are type 1 and 2 neurofibromatosis and schwannomatosis, von Recklinghausen disease also known as type 1 neurofibromatosis has an autosomal dominant inheritance. It is the commonest form as and presents with numerous café-au-lait macules and neurofibromas. Giant congenital melanocytic nevus (CGMN) on the other hand is characterized by a melanocytic proliferation that present at birth. CGMN develops due to a defective embryonic pigment cell (melanocyte) precursors development and are often present at birth. Giant congenital melanocytic nevus (CGMN) and type 1 neurofibromatosis may occur together rarely. Clinicians should be aware of the rare presentation of both CGMN and type 1 neurofibromatosis in a patient.
