inflammation of the skin, red border, and mucosa of the lips. Cheilitis has many causes; for example, it may occur as a manifestation of any one of several diseases, including lupus erythematosus. The condition is characterized by reddening, edema, burning, itching, and formation of blisters, ulcers, cracks, scales, and serous-bloody crusts. Acute cheilitis is manifested by eczema or an allergic reaction to a chemical irritant, for example, lipstick or toothpaste. Mycotic cheilitis is caused by yeast fungi, and actinic cheilitis results from prolonged exposure to solar radiation. Exfoliative cheilitis is an inflammation resulting from functional disorders of the nervous system; superficial and deep impetiginous glandular cheilitis is caused by purulent inflammation of the accessory salivary glands.
Treatment is directed toward removing the basic cause. Corticosteroids (in the form of creams and ointments), vitamins, and aqueous solutions of aniline dyes may be applied. Treatment may also include rinsing the mouth with a twoto five-percent soda solution.
