What is disseminated superficial actinic porokeratosis (DSAP)?

Disseminated superficial actinic porokeratosis (DSAP) is a rare, non-cancerous, non-contagious skin disorder. Disseminated means that it is widely spread, most likely over the front and lower arms and legs -- areas that are typically frequently exposed to sun over a period of time. Superficial means that DSAP occurs on the outer layer of the skin. Actinic refers to effects of sunlight rays that can cause changes in the regular chemical activities of the skin. Porokeratosis means that these skin changes are seen as a variety of flat, thickened lesions with slightly raised rims. You can feel this flaky rim when running your hand lightly down the arms and legs. DSAP is a chronic disorder; it can be treated, but it cannot be cured.
