Title: [Effectiveness of vitamin A acid in diseases of the mouth mucosa: lichen ruber planus, leukoplakias and geographic tongue]. Author: Günther S. Journal: Z Hautkr; 1975 Jan 01; 50(1):41-6. PubMed ID: 1216954. Abstract: 52 patients, with different pattern of oral lichen planus, pre-malignant leukoplakia or geographic tongue, were treated with vitamin A acid. The systemic medication resulted in regression of discrete papules and leukoplakia-like appearance of oral lichen planus. Linear-hypertrophic pattern of the oral mucosa showed distinct involution only by topical administration of vitamin A acid. Also the patients suffering from pre-malignant leukoplakia or geographic tongue partly improved after a vitamin A acid therapy. Systemic side effects were noted after ignoring the tolerance limit (30 mg/day vitamin A acid/3 weeks). Inflammation and occasionally maceration appeared when local treatment was used over 3 weeks. Recurrence was observed in 11 patients.[Abstract] [Full Text] [Related] [New Search]
