Abstract
Although oral erythroplakia is accepted as one of the oral precancerous lesions with high potentiality for malignant transformation, there has been few reports about it because the incidence is rarer than oral leukoplakias. Three cases of oral erythroplakia during six years were presented. These lesions clinically were bright red, had a clear outline, and contacted instable dentures. Pathologically, they were diagnosed as moderate or severe dysplasia and one case transformed to invasive carcinoma after a long-term clinical course.
This case supports the opinion that oral erythroplakia should be resected as a malignant lesion as soon as possible.
