Dermoscopic Features of Hyperpigmented Dots in Crista Cutis in Two Siblings in a Japanese Family with Inherited Acanthosis Nigricans
Abstract: Acanthosis nigricans is characterized by papillomatous brownish lesions mainly in the intertriginous areas. We used dermoscopy to examine such lesions in a family with acanthosis nigricans. The dermoscopic images showed an aberrant skin structure of linear crista cutis and sulcus cutis, and hyperpigmented dots in crista cutis. The hyperpigmented dots, which could not be seen with the naked eyes, may contribute to the color of the pigmented skin. Dermoscopy can be useful for evaluating disorders involving the structure of area cutanea and a change in skin color.
