What it is
It is mainly linked to long-term sun exposure and is most common in older adults.
Treatments include freezing, creams, light therapy (PDT) and minor surgery. Protecting the skin from the sun helps prevent new patches.
Common signs
- A red, scaly patch that may be itchy
- A patch that slowly gets bigger
- Patches on sun-exposed areas, especially the lower legs
How it is usually diagnosed
- Examination of the skin, often with a dermatoscope
- A skin biopsy to confirm
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Biopsy reports
- Photos of patches with dates
- Dermatology letters and treatment notes
Questions to ask your doctor
- Which treatment is best for this patch?
- How do I check my skin for new patches?
- Do I need regular skin checks?
When to get help right away
