Summary

Keratosis pilaris is a cutaneous abnormality of follicular hyperkeratosis that is physiological in most cases. In other cases, it may be part of a disease or syndrome. It is characterized by small, folliculocentric keratotic papules that usually have surrounding erythema. The disorder most commonly affects the extensor aspects of the upper arms, upper legs, and buttocks. Patients with this condition usually are asymptomatic.
