Congenital Melanocytic Nevus
A Congenital Melanocytic Nevus (CMN) is a benign lesion present at or shortly after birth, often appearing as a flat, tan macule resembling an irregular cafe-au-lait spot. Over time, CMNs may exhibit changes such as altered pigmentation, surface thickening, or increased hair growth. These nevi commonly appear on the trunk and extremities. There is an elevated potential for melanoma development especially in larger lesions.
