[Oral leukoplakias--a histopathological and retrospective study].

Abstract

In a retrospective study 85 patients of our department with clinical oral leukoplakia occurring between 1980 and 1985 were checked histologically and reclassified. Compared to other studies and unusual high malignant transformation rate (14.1%) was found which seemed to be depended on the high rate of radiated patients. Four of twelve patients were healed due to early diagnosis and radical surgery performed consecutively. Using these data as a basis the different courses and therapies are demonstrated.
