Hyperkeratosis-hyperpigmentation syndrome: a confirmative case.

ABSTRACT

A 22-year-old female showing hyperpigmented spots and mild palmoplantar hyperkeratosis as leading features is presented. The diagnosis of Hyperkeratosis-hyperpigmentation syndrome, previously described by our group as an autosomal dominant trait, was unmistakable, thus permitting the corroboration of this genodermatosis.
