Solar Keratosis
(Actinic Keratosis)
(Senile Keratosis)

Description : Solar Keratoses are considered to be premalignant lesions which arise on the sun-exposed areaas of the skin. They occur most commonly after the third decade of life in individuals who have fair skin.

Clinically, solar keratoses appear as dry, rough, adherent scaly lesions. Occassionally, solar keratoses produce a circumscribed, conical hyperkeratotic excrescence, which is termed a "cutaneous horn".

A solar keratosis has produced a dry, elevated, white, scaly lesion on the posterior helical rim.
