title: [Exfoliative cytology during topical treatment of oral leukoplakia with vitamin A acid].
abstract: Vitamin A acid (VAS) has proved itself an effective local therapeutic agent for intra-oral leucoplakia. Clinical remission characterized by a decrease in horny lumps and the eosinophilic index and an increase in intermediary cells was achieved in 32 out of 50 cases. In the course of maintenance therapy development towards an exfoliocytologically healthy mucosa proceeds via increasing parakeratosis. VAS therapy is essentially thought of as symptomatic therapy.
