CUNHA FILHO, Roberto Rheingantz da and ALMEIDA JR, Hiram Larangeira de. Focal acral hyperkeratosis with hypochromic dermatoglyphics. An. Bras. Dermatol. [online]. 2008, vol.83, n.5, pp.441-443. ISSN 1806-4841. http://dx.doi.org/10.1590/S0365-05962008000500008.
Focal acral hyperkeratosis is a rare condition, characterized by acral keratotic papules that preferably affect hand and foot surfaces, and are included in the spectrum of marginal papular keratodermas. We report an unpublished variant of this condition, the case of a 45-year-old Caucasian woman with acral keratotic papular lesions and hypochromic dermatoglyphics in the feet. Histological examination revealed orthohyperkeratosis, depression of the epidermis, acanthosis and hypergranulosis. Topical treatments with keratolytics were ineffective, similarly to previously described cases.
