Actinic keratosis develops after several years and repeated sun exposure or indoor tanning. There are typically no symptoms other than a rough, scaly patch of skin that eventually appears. The patch may be itchy and also may disappear and reappear again.
Skin conditions including actinic keratosis can be diagnosed during an exam with a dermatologist. Actinic keratosis may vary in look so it is important to see a dermatologist anytime you have a skin change. If there is ever question about a new lesion a skin biopsy can be performed to confirm a diagnosis.
