Two Cases of Congenital Giant Melanocytic Nevus (CGMN) with Vitiligo / 대한피부과학회지

ABSTRACT

Congenital giant melanocytic nevi (CGMN) are lesions of more than 20 cm in diameter, often in the distribution of a garment. Depigmented zones may appear around several types of acquired lesions such as dermal, junctional, and compound nevi, Spitz nevus, blue nevus, and malignant melanoma. The depigmentation may occur within the lesion, around it, or at a distant site. In contrast, congenital nevi rarely develop depigmentation. Vitiligo-like leukoderma distant from the nevus has developed in only three cases with a CGMN. We report two cases of CGMN with vitiligo which is located away from primary CGMN lesion.
