Dermoscopy of black skin: A cross-sectional study of clinical and dermoscopic features of melanocytic lesions in individuals with type V/VI skin compared to those with type I/II skin.

Abstract：

BACKGROUND:The identification of "normal" dermoscopic patterns of acquired melanocytic nevi provides better diagnostic accuracy for melanoma in people with black skin. OBJECTIVE:We sought to describe melanocytic lesions (numbers and anatomic distributions) in skin types V and VI compared with skin types I and II, according to the Fitzpatrick classification. We sought to identify differences in dermoscopic findings in acquired melanocytic nevi (global pattern, pigment and color distribution) between the groups. METHODS:We conducted cross-sectional, prospective, and consecutive data collection in 2 dermatologic outpatient clinics, between October 8, 2010, and March 20, 2013. From the 501 volunteers, 480 participants fulfilled the eligibility criteria. A total of 460 acquired melanocytic nevi were selected for dermoscopic analysis. RESULTS:Individuals with skin type V/VI had fewer melanocytic lesions than those with skin type I/II (15.08 vs 7.90; P = .032), and the anatomic distribution in the first group was predominantly on the face and acral sites (P < .001). The acquired melanocytic nevi in the skin type V/VI group were associated with the reticular pattern (P < .0001), with a tendency toward central hyperpigmentation (P = .0025). LIMITATIONS:The choice of a single representative nevus per patient is a limitation. CONCLUSIONS:Acquired melanocytic nevi in individuals with skin type V/VI have a distinct dermoscopic pattern from those with skin type I/II.
