Marginal papular acrokeratodermas: no racial limitations for a clinical spectrum that responds to acitretin.

Marginal papular acrokeratoderma (MPA) encompasses a group of disorders that share crateriform, keratotic papules along the margins of the hands and feet. We report a unique case of a Philippino woman, with focal acral hyperkeratosis (FAH) associated with sensorineural hearing loss. The clinical phenotype of FAH (hereditary MPA without elastorrhexis) is expanded and the hypothesis of a racially limited disorder is weakened. Effective treatment of this embarrassing condition with acitretin is demonstrated.
