What is Topical application of vitamin A to oral leukoplakia : A clinical case series about?

## BACKGROUND. Due to the possibility of malignant transformation of oral leukoplakia, these lesions must be assessed and managed closely and, if not resolved, must be reassessed on a regular basis. ## METHODS. This study evaluated the use of topical 0.05% vitamin A (tretinoin) acid gel for the treatment of oral leukoplakia. Tretinoin was applied topically 4 times a day for the management of nonmalignant oral white lesions in 26 patients. The clinical response was evaluated in all patients and posttreatment biopsies were performed in ten patients. ## RESULTS. The mean age of the patients at the time of diagnosis was 62 years. Of the 26 patients, 50% were tobacco users. Patients were followed for a mean of 23 months. Approximately 27% of the patients had a complete clinical remission. Recurrence of leukoplakia was observed in approximately 40% of patients in whom complete clinical remission occurred if topical applications were discontinued. A 50% reduction in the clinical grade of leukoplakia from a mean of 2.8 to 1.4 on a scale ranging from 0 (no leukoplakia) to 4 (speckled leukoplakia) was observed. When the pretreatment and posttreatment biopsies from 10 patients were evaluated,
