Abstract
Cheilitis is a general term for the inflammation of the lip. Exfoliative cheilitis is the rarest type of cheilitis and is characterized by superficial desquamation of the lip vermilion. We report a case of exfoliative cheilitis related to intense sun exposure in a 22-year-old White male patient with 4 months of evolution. The lips presented edema, dryness, desquamation, and multiple thick, yellowish-white crusts. Sialometry, serologic tests, and cytopathology showed no alterations. An incisional biopsy was performed, and the histopathologic examination revealed parakeratinized squamous epithelium with mild lymphocytic exocytosis and a scanty chronic inflammatory infiltrate in the underlying connective tissue. Treatment with topical corticosteroids was performed for 12 weeks and total remission of the lesions was observed. However, 2 months later, the lesions recurred and required topical corticosteroid intervention for another 12 weeks. After this treatment, complete healing occurred, and the patient remains in follow-up for 1 year.
