A Case of Reticulate Acropigmentation of Dohi Presented on the Trunk

Abstract

Reticulate acropigmentation of Dohi is a rare dyschromic disorder that has an autosomal dominant pattern of inheritance. It presents generally during infancy or early childhood as symmetrical pinpoint to pea-sized hyperpigmented and hypopigmented macules on the back of the hands and feet. The eruption slowly extends proximally and may rarely affect the sides of the neck and upper portion of the trunk. We report a case of reticulate acropigmentation of Dohi on the trunk of a patient with a family history of the disorder in four generations. To our knowledge, this is the first report in the Korean literature that describes skin lesions on the trunk in a patient with reticulate acropigmentation of Dohi.
