After a DSAP Diagnosis: Notes for Your Skin Review

After a dermatologist names the patches as disseminated superficial actinic porokeratosis, or DSAP, you may want a clear answer to “What should I watch for?” Ask for a monitoring plan you can follow without inspecting your skin every time you pass a mirror.

Report a change before perfecting the record

BAD’s 2025 leaflet advises reporting changes to your GP or dermatologist. Very rarely, squamous cell carcinoma can develop at a DSAP site; an enlarging raised lump, sometimes painful, is a described warning change.¹

If you notice a change, contact the team using its instructions. Do not postpone that contact to collect more photographs. Tell them which area changed and when you first noticed it. Ask how soon it needs examination.

Record what you can describe

DSAP areas often feel dry and rough and may have no symptoms. Sun exposure can bring itching or stinging and increases in their size or number.¹

For the appointment, note the date, location and the change you noticed. Describe itch, stinging or discomfort in your own words. If photographs help explain a change, ask the team how to take and share them. The clinician should interpret what the change means.

Separate your observations from guesses about the cause. “This area began stinging last week” gives the team something concrete to discuss. Ask whether a different patch also needs examination rather than assuming every mark has the same diagnosis.

Ask what the proposed treatment is meant to achieve

The leaflet describes treatment discussions when itch or appearance is troublesome. It says many treatments do not change the long-term outcome and some carry significant side effects. These limits should be discussed for the particular option offered.¹

Tell the dermatologist which concern matters most to you. Ask what improvement it expects, what risks apply at that site and when it will review the response. Request instructions for any prescribed product and a contact plan if the reaction worries you. Do not copy another person’s treatment schedule.

Keep protection and review instructions together

BAD recommends protecting affected skin from further sun damage, with clothing, shade and sunscreen. Sunscreen adds protection but cannot provide complete protection on its own.¹

Ask how to fit the advice into your work, clothing and usual time outdoors. Confirm whether the next skin review is booked, which changes to report sooner and whom to contact. Keep those answers beside any treatment instructions.
