Circumscribed acral hypokeratosis (CAH) is a rare dermatosis that typically appears as well-dermarcated erythema with a scaly border on the palms or soles of middle-age patients. A pediatric case of CAH has been recently reported in a 10-year-old boy affecting the medial foot since birth. In this report we describe the second congenital case of CAH on the sole.
