Full Definition
Keratosis pilaris is an extremely common benign disorder of keratinization affecting up to 80% of adolescents. It presents as small, rough, flesh-colored to erythematous papules in a follicular distribution, most commonly on the lateral upper arms, thighs, and buttocks. The condition is often associated with atopic dermatitis and tends to worsen in dry climates. While cosmetically concerning to patients and parents, the condition is harmless and often improves with age. Medical writers should emphasize the benign nature while acknowledging the cosmetic concerns that prompt medical consultation.
