How common is skin sore that does not heal in actinic keratosis?

Actinic keratosis develops in skin that has received cumulative ultraviolet exposure. It may feel rough, dry, scaly, tender, or crusted, and a sore may persist or reopen after seeming to settle. Appearance can overlap with other skin conditions, including skin cancers, so a persistent change deserves an examination rather than self-diagnosis. A clinician may inspect the area closely and sometimes sample it to clarify the diagnosis.

Book a dermatology or primary-care review for a sore that is not healing. Note when it began, whether it bleeds or crusts, and whether its size, colour, texture, or tenderness changes. Do not pick the crust or apply leftover prescription creams. Protect the area from sunlight with clothing and shade, and use sunscreen on exposed skin as directed. Treatment may involve removing or treating abnormal surface cells, depending on the examination.

Seek an earlier appointment if the area repeatedly bleeds, becomes painful, grows, forms a firm edge, or changes quickly. Get urgent help for uncontrolled bleeding, spreading redness with fever, or severe pain. A sore that persists should be assessed even when it is small or only mildly uncomfortable.

Ask whether the area looks like actinic keratosis, whether a biopsy is needed, which treatment fits its location, and how to protect the surrounding skin. Ask how to check for new rough or crusted spots and when the area should be reviewed again.
