Siblings with dyschromatosis universalis hereditaria a rare case report

Abstract

Dyschromatoses are a group of genodermatosis characterized by the presence of both hyperpigmented and hypopigmented macules of variable shapes and sizes. Here, we report siblings presented with asymptomatic progressive mottled pigmentation of reticulate pattern over the trunk and limbs since 6 years of their age without any systemic or other cutaneous illness. They were born to nonconsanguineous parents following an uneventful pregnancy. Their paternal grandfather had a similar appearance. Histological examination was consistent with dyschromatosis universalis hereditaria (DUH). Based on the clinical and histological findings, a diagnosis of DUH was made. We report this case of rare genodermatosis in siblings affected by the same disease.
