Abstract

Circumscribed palmar or plantar hypokeratosis is a rare dermatosis, and it consists of asymptomatic erythematous, well-circumscribed and depressed patch with scaly borders on the palm or sole. It usually affects middle-aged or elderly women. Histopathologically, it has a sharp stair between the normal and involved skin, and a demarcated area with an abrupt decrease in the horny layer thickness. We report herein a case of circumscribed palmar hypokeratosis that was successfully treated with cryotherapy.
