Reticulate acropigmentation of dohi: Dermatoscopic features in two cases

Abstract

Reticulate acropigmentation of Dohi is a rare genodermatosis inherited as an autosomal dominant trait. It is a localized form of dyschromatosis universalis hereditarian, characterized by the presence of hyperpigmented and hypopigmented macules with symmetrical, irregular size and shape forming a reticulate pattern over the dorsa of the hands and feet. Onset is normally in the first decade but occasionally be delayed. Biopsy is not diagnostic but helps to rule out its differentials. Dermoscopy is a new investigative tool which gives specific characteristic changes. We report two cases of acropigmentation of Dohi with classical dermatoscopic changes reported previously and some new features. No treatment is effective for this genodermatosis.
