Cryotherapy for the treatment of acne keloidalis [a clinical interventional therapeutic trial]

ABSTRACT

Background: Acne keloidalis is a condition characterized by follicular-based papules and pustules that form hypertrophic or keloid-like scars. It typically occurs on the occipital scalp and posterior neck and develops almost exclusively in young people with dark skin. Unlike true acne vulgaris, comedones are not seen. The condition has a great psychosocial impact. The exact etiology of AK is nuclear. It is thought that chronic irritation from coarse, curly hairs in the skin leads to inflammation and development of these lesions. It has also been shown that men who have haircuts more frequently than once a month are at higher risk of developing acne keloidalis
