Actinic Keratosis of Scalp

This photo shows An actinic keratosis of the scalp. These lesions are often difficult to see.
Description: They are rough, sandpaper-like plaques occurring on sun-exposed surfaces. They are pre-malignant, since a small percentage of them develop into squamous cell carcinoma. The lesion here is darker than the surrounding skin; the lighter area is from the camera flash.
