Abstract
- Circumscribed palmar or plantar hypokeratosis is a rare disease that is characterized by a well-circumscribed, erythematous depressed macule or patch on the palm or sole. It usually presents as an asymptomatic, solitary lesion in middle-aged or elderly women. The characteristic histopathological finding is a sharp stair-like alteration between involved and uninvolved skin with a markedly thinner horny layer and slightly decreased granular layer compared with adjacent normal skin. Herein we report a case of circumscribed palmar hypokeratosis and review the literature.
