title: Circumscribed palmar hypokeratosis: new observations.
abstract: Circumscribed hypokeratosis is a characteristic depression both clinically and histopathologically that was originally described as representing a distinctive acquired epidermal malformation of volar skin. To date, 16 patients with this entity have been reported. On the basis of clinical features and histopathologic findings in 4 new patients, coupled with information about some of the previously reported patients, there is evidence to suggest that this dermatosis could be secondary to trauma.
