[Severe laryngeal dysplasia and synthetic retinoids].
Nine patients with "severe" laryngeal dysplasia as shown by multiple microbiopsies during laryngoscopy were treated with a synthetic derivative of retinol (Etretinate 0.5 to 1 mg/kg/day) over one or two months. Follow up histology after 8 to 18 months surveillance showed histologic improvement with respect to dyskeratosis, atypical cells and to a lesser extent epithelial hyperplasia. The use of synthetic vitamin A derivatives for "severe" laryngeal dysplasia is discussed.
