(kŏm′ă-dō) plural.comedonesplural.comedos [L. comedere, to eat up]
The typical small skin lesion of acne vulgaris and seborrheic dermatitis. The closed form is called a whitehead. It consists of a papule from which the contents are not easily expressed. When inflamed these lesions form pustules and nodules. The open form of comedo, called a blackhead, is rarely inflamed. It has a dilated opening from which the oily debris is easily expressed. Both forms are usually located on the face, but the chest and back may be involved.
