Facial presentation of disseminated superficial actinic porokeratosis.
A case of disseminated superficial actinic porokeratosis (DSAP), an autosomal dominant genodermatosis possessing a pathognomonic cornoid lamella, is presented. Exclusively facial disseminated superficial actinic porokeratosis is an unusual clinical presentation, although 15% of patients having the condition in the typical generalized form have facial lesions. There is no specific treatment. In selected cases, lesions may be excised, electrodesiccated, or sprayed with liquid nitrogen. Topical steroids and topical 5-fluorouracil have been reported to be beneficial in some instances. Sunscreens should be tried as a preventive measure, especially in family members of patients with known DSAP.
