Dyschromatosis symmetrica hereditaria: Report of a sporadic case in a Nigerian child
Abstract
Abstract Dyschromatosissymmetricahereditaria (DSH) is one of a group of reticulate pigment disorders of the skin. It is a rare
autosomal dominantly inherited genodermatosis, presenting as mottled admixtures of hypopigmented and hyperpigmented
macules on the dorsa of the extremities. It is predominantly found among persons of Oriental origin. We hereby document the
first case of dyschromatosissymmetricahereditaria in a four year old Nigerian boy who presented with progressive symmetric
dyschromic lesions on the dorsa of the hands and feet, with no family history of similar lesions. The diagnosis was confirmed by the typical histologic finding of basal hyperpigmentation with normal number of melanocytes and absence of melanin incontinence from a hyperpigmented lesion
