Kératose pilaire

Keratosis pilaris is characterized by small bumps around hair follicles. Keratosis pilaris simplex results in gray and keratotic papules mainly on the arms, thighs and buttocks. It mainly affects women. Keratosis pilaris rubra often results in keratosis pilaris atrophicans. Common variants of keratosis pilaris include: ulerythema ophryogenes, atrophoderma vermiculata, Siemens alopecia. Keratosis pilaris is a genetic disorder and can occur in association with other hereditary diseases such as Noonan syndrome or vitamin disorders. Treatment is mainly based on emollients and keratolytics, but they have only a suspensive effect. We report the case of a 30 year old woman with a personal and family history of atopy, presenting with diffuse keratotic papules on the trunk. The remainder of the physical examination revealed no genetic abnormality. Treatment was based on emollients and keratolytics with slight improvement.
