Keratosis pilaris atrophicans faciei L66.-

Keratosis pilaris atrophicans faciei is a facial manifestation of keratosis pilaris simplex. The carriage and chin region is affected. In addition to follicular horny papules, a flat, satin-red erythema is often detectable (frequently referred to as erythema perstans ).

Always appearing symmetrically on both cheeks, flat, saturated red, asymptomatic, hardly scaling, not painful or itchy erythema with 0.05-0.1 cm follicularly bound hyperkeratoses.

Prolonged persistence, with persistent areal redness, results in gradual loss of hair follicles with scarring.

Over the course of years, analogous atrophic processes may also occur at the forehead-hair interface (postmenopausal frontal fibrosing alopecia) or in the eyebrow region (ulerythema ophryogenes).

Concomitant: Commonly keratosis pilaris simplex in the extremities (Coelho De Sousa V et al. (2018).

Additionally concomitant, although rare, is the appearance of comedones and pustules.

Chronic but absolutely benign clinical picture. The process ends by the complete atrophy of the follicle in an inconspicuous, follicle-replacing. white scar.

Atrophodermia vermiculata is the scarring, follicle-free final state of an asugeous keratosis pilaris atrophicans faciei.

The skin-colored follicles are characterized by bizarre angular or cuspate formations. They are otherwise non-irritant. Sebaceous glands or vellus hairs are completely absent.
