Actinic keratosis
Actinic keratosis is a scaly spot found on sun-damaged skin. It is also known as solar keratosis. It is considered precancerous or an early form of cutaneous squamous cell carcinoma (a keratinocyte cancer)

Actinic keratoses affect people who have often lived in the tropics or subtropics and have predisposing factors such as:

What Causes Actinic Keratoses?
Actinic keratoses are a reflection of the abnormal development of skin cells due to DNA damage from short wave UVB.
They are more likely to appear if immune function is poor, due to aging, recent sun exposure, predisposing disease, or certain medications.

Actinic keratosis can be solitary, but there are often multiple keratoses. Appearance varies.
