Two novel mutations of the ADAR1 gene in Chinese patients with dyschromatosis symmetrica hereditaria successfully treated with fractional CO2 laser

A Case Report of Dyschromatosis Symmetrica Hereditaria with Glucose-6-Phosphate Dehydrogenase Deficiency

Dyschromatosis symmetrica hereditaria (DSH) is a pigmented genetic skin disorder with an incompletely understood pathogenesis characterized by reticular hyper- and hypopigmented skin patches on the dorsal aspect of the extremities, freckle-like patches on the face, and unaffected palms and feet. There is no effective treatment available. Glucose-6-phosphate dehydrogenase (G6PD) deficiency has not been reported in the literature of DSH. We describe for the first time a case of DSH with G6PD deficiency and a family history of psychosis.

Clinical and Genetic Review of Hereditary Acral Reticulate Pigmentary Disorders

Reticulated pigmentation is a unique pigmentary change caused by a heterogeneous group of hereditary and acquired disorders. This pigmentation is characterized by a mottled appearance, with lesions that vary in size and pigmentary content. This review discusses the hereditary group of the reticulated pigmentation disorders, such as dyschromatosis symmetrica hereditaria, dyschromatosis universalis hereditaria, and reticulate acropigmentation of Kitamura. The clinical presentation and histopathological features often overlap, making diagnosis difficult. However, each of these hereditary conditions possesses a unique genetic mutation, and genetic analysis is thus more useful in the diagnosis of these conditions. This article delivers an update regarding the clinical features, detailed histopathological description, and genetic information concerning hereditary reticulate pigmentary disorders and aims to provide useful background for use by clinical dermatologists and histopathologists when approaching this group of hereditary disorders.
