Abstract
- Circumscribed acral hypokeratosis (CAH) is a rare disorder characterized by a well-circumscribed and erythematous depressed patch on the palm or sole. It usually presents as an asymptomatic, solitary, long-standing lesion in middle-aged to elderly women. Histologically, it has a characteristic stair-like configuration between normal and involved skin with an abrupt thinning of the horny layer and a decreased granular layer. Although the pathogenesis of CAH is not well established, several hypotheses were proposed. To our knowledge, there have been only two cases to document HPV in a single lesion of CAH. Herein, we report the third case of circumscribed acral hypokeratosis with expression of human papillomavirus, high-risk type 16, 18.
