Proliferative Nodule in a Giant Congenital Melanocytic Nevus / 대한피부과학회지

The proliferative nodules within a giant congenital melanocytic nevus (GCMN) are generally benign and may regress. However, atypical features cause great interest in dermatopathology. Especially, in neonate proliferative nodules with bleeding, ulceration on GCMN makes it difficult to differentiate the nodules from congenital malignant melanoma. Herein, we describe an interesting case of proliferative nodules in a GCMN of a newborn, which has not been previously reported in Korea.
