A stucco keratosis, also known as a keratosis alba or keratoelastoidosis verrucosa, is a white or gray scaly papule that typically appears in adults older than 40 years on the dorsal feet and lower legs. Less commonly, the hands and forearms may be involved. Individuals with stucco keratoses typically have a large number of lesions. The lesions are benign and asymptomatic.

Stucco keratoses are more common in patients of Northern European descent, and men are thought to be 4 times more likely to have stucco keratoses than women.
