Dyschromatosis universalis hereditaria (DUH) is a rare pigmentary disorder characterized by the presence of mottled hyperpigmented and hypopigmented macules over the trunk, extremities, and face. We have presented a case series comprised of six members of a family who had numerous hyperpigmented and hypopigmented macules distributed all over the body. Histological findings were suggestive of dyschromatosis universalis hereditaria.

ABCB6 has been implicated in dyschromatosis universalis hereditaria, a condition characterized by hyperpigmented and hypopigmented skin macules. Dyschromatosis universalis hereditaria can also present with hearing loss. Dyschromatosis universalis hereditaria-associated mutations in ABCB6 have been reported, but the role of this protein in the inner ear has not been studied.

Article Synopsis
- * It can resemble other skin disorders but is distinguishable by its unique histopathological features.
- * Diagnosis may require a biopsy, as seen in a case where a 50-year-old female was confirmed to have DDD despite no family history or abnormal lab tests, highlighting the need for awareness of rare skin conditions in medical evaluations.

Reticulate pigmentary dyschromatoses primarily include dyschromatosis universalis hereditaria (DUH), dyschromatosis symmetrica hereditaria (DSH) (Reticulate acropigmentation of Dohi), and unilateral dermatomal pigmentary dermatosis, which differ in their patterns of distribution. The disease was initially described by Ichikawa and Hiraga in Germany in 1933. The prevalence of DUH is 0.

Rationale: Dyschromatosis universalis hereditaria (DUH) is an uncommon form of pigmented genodermatosis that is typically inherited autosomally and dominantly. In the previous study, the pathogenic genes of DUH have been identified in ATP-binding cassette subfamily B, member 6 and SASH1. However, the mutational screening of the causative gene remains incomplete and still lacks sufficient proof in the etiology.
