DSAP appears as annular patches of pale pink skin. The centre of the lesion is often smooth however it can be dry and scaly.
The patches have a slightly raised edge that is best seen with a dermatoscope. This border is often darker than the rest of the lesion.
DSAP is more commonly seen on sun exposed areas of the lower arms or legs.
The appearance may not be that specific and the diagnosis is usually confirmed with a punch biopsy.
