Dyschromatosis universalis hereditaria in a young Nigerian female.

Dyschromatosis universalis hereditaria (DUH) is a clinically heterogeneous disorder that shows generalized mottled pigmentation. It occurs most commonly in Japanese persons, with sporadic reports from South Africa, India, and Iraq. Histopathology reveals a variable degree of pigmentary incontinence. Although the precise etiology of this disorder is not yet known, the clinicopathological findings implicate an inherent abnormality of melanosomes or melanin processing. We describe a case in a young Nigerian girl.
