Acrokeratosis Verruciformis of Hopf: a localized variant.

Acrokeratosis Verruciformis of Hopf (AKV) is a rare autosomal dominant genodermatosis. It usually develops during early childhood affecting both sexes equally. Typically, the lesions are warty to convex, brownish to skin-colored papules on the dorsa of the hands and feet, forearms and legs. A possible relationship with Darier disease has long been postulated on a clinical basis mainly. But recently, evidence has suggested that AKV and Darier disease are allelic disorders. I am reporting these two unrelated cases as a unilateral localized variant of AKV.
