Dowling-Degos disease: a classic presentation of a rare disease

Dowling-Degos disease (DDD) is an autosomal dominant disorder characterized by acquired, reticulate hyperpigmentation in flexural areas. It is a rare condition with very few cases reported in the literature. Although clinically similar to a number of other reticulate pigmentary disorders, it has some characteristic dermoscopic and histopathological features that aid in its diagnosis. We describe the case of an Indian female presenting with classical clinical, dermoscopic, and histological features of DDD.
