title: Circumscribed palmar hypokeratosis.
abstract: A 66-year-old woman presented with a 40-year history of a slowly enlarging erythematous patch on the left thenar eminence. Histopathology showed a sharp 'step' between the uninvolved and involved skin. Epidermal dysplasia and a cornoid lamella were not seen. These are the typical features of circumscribed palmar hypokeratosis.
