Disseminated superficial actinic porokeratosis (DSAP) is an uncommon skin condition that leads to reddish brown scaly spots. The spots are mostly visible on the arms and legs, but sometimes will show up on other sun-damaged skin. It is due to an abnormal sun sensitivity leading to precancerous skin cells. It is not a serious condition.
HOW IS DSAP DIAGNOSED?
The diagnosis of DSAP is done by a dermatologist. The specialist will perform a physical examination and get details of medical and family history. Biopsy is one of the test conducted to detect the disorder.
HOW IS DSAP TREATED?
There are different kinds of over the counter creams and ointments available that help in treating the same. Some of these include Cryotherapy, 5-Fluorouracil cream and Imiquimod cream that are applied externally to provide some respite from the same.
DID YOU KNOW?
DSAP is more common in women than in men and normally develops between 30-50 years of age. It is not contagious. Very rarely, inherited forms of DSAP can appear in childhood. Once a spot of DSAP forms, it may slowly enlarge to form a ring or circle. The spots seem to grow or itch after sun exposure.
