ZANINI, Maurício. Focal acral hyperkeratosis: case report and discussion on marginal keratodermas. An. Bras. Dermatol. [online]. 2006, vol.81, suppl.3, pp.S293-S296. ISSN 0365-0596.

The author reports a case of focal acral hyperkeratosis, an affection of the group of keratodermas, characterized by papular or plaque eruption in the palmoplantar borders whose onset is usually before 20 years of age, and predominates among black-skinned patients. The main differential diagnosis is acrokeratoelastoidosis of Costa, differing from the former only for not presenting elastorrhexis in histopathology.

Keywords : Keratin [genetic]; Keratoderma palmoplantar [classification]; Keratoderma palmoplantar [diagnosis]; Keratosis.
