Atypical cases of Dowling-Degos disease

Abstract

Dowling–Degos disease (DDD) is a rare autosomal dominant condition characterized by multiple, small, round pigmented macules usually arranged in reticular pattern, chiefly distributed in axillae and groins. Here we are reporting three atypical cases of DDD in a family. They had hypopigmented macules with typical features of DDD indicating generalized DDD. Histopathology confirmed the diagnosis. We present these three cases to stress the existence of generalized DDD phenotype in the Indian population.
