tinea of the bearded area of the face and neck. There are three types: in the inflammatory type, usually caused by Trichophyton mentagrophytes or T. verrucosum, lesions are usually kerions or nodules and may produce crusting; in the ringworm type, the annular lesions resemble those of tinea corporis; and in the sycosiform type (t. sycosis), caused by T. violaceum or less often T. rubrum, lesions are follicular pustules containing hairs that may break off and leave a stub or may become epilated. Called also barber's itch and ringworm of the beard.Medical dictionary. 2011.
