title: Circumscribed palmar hypokeratosis associated to a burn scar.
abstract: Circumscribed palmar or plantar hypokeratosis is a volar depression characterized by a circular area of well-circumscribed and erythematous skin on the palm or sole. It is a benign condition that occurs mainly as an asymptomatic lesion on the thenar or hypothenar areas of the palm of middle-aged or elderly patients. Since its first description 1 decade ago, the pathogenesis of this entity still remains unclear. Herein we report the first case of a circumscribed palmar hypokeratosis lesion associated to a burn scar, which corroborates the hypothesis of an acquired disorder caused by trauma.
