cheilitis glandularis

a rare disease in which the lower lip becomes enlarged and later everted, exposing inflamed and dilated openings of accessory salivary glands; the glands themselves are enlarged and sometimes nodular. It may be associated with carcinoma of the lip. There are three types: the simple type is characterized by painless pinhead-sized lesions and may develop into one of the other types; the superficial suppurative type (called also Baelz disease) is characterized by painless swelling, induration, crusting, and ulcerations of the lip; and the deep suppurative type is a deep-seated infection with abscesses and fistulous tracts that eventually form scars. Called also apostematous c., c. glandularis apostematosa, and myxadenitis labialis.
