Giant congenital melanocytic nevus with neurotized lesions mimicking neurofibromas – A rare presentation

Abstract

Giant congenital melanocytic nevus (GCMN) is a deeply pigmented lesion, often associated with hypertrichosis and multiple scattered satellite lesions. During infancy apart from textural changes, rapidly growing “proliferative nodules” mimicking melanoma can occur in the nevus. Areas of the nevus may be infiltrated by an overgrowth of fat or nerve tissue, so-called lipomatous or neurotized areas, respectively, common in larger nevi. We report a case of GCMN associated with multiple neurotized areas mimicking large neurofibromas, a rare phenomenon.
