(Myxadenitis labialis; Cheilitis glandularis; Cheilitis glandularis apostematosa; Cheilitis exfoliativa; Psoriasis labialis).
The synonymous, just mentioned, have been variously applied by different investigators, to condition chiefly affecting the mucous and cutaneous surfaces of the lower lip. The affected area becomes tumid and tense, at times painful, and is studded with pin-point- to hemp-seed-sized, elevated, mucous glands with dilated follicular orifices from which exudes a thin serum or a mucoid or mucopurulent fluid. Crusting may be marked, the lips becoming agglutinated during the hours of sleep and when long at rest in the hours of the day. Scaling, instead of crusting, has been noted in some cases.
Etiology, Prognosis and Treatment. The cause of this disease is not known, although vegetable organisms have been found. It is persistent and does not respond readily to treatment. Aseptic local measures, mild cauterization and careful X-raying are indicated.
