Erythroplakia (from the Greek erythros = red and plakia = patch) is defined by the World Health Organization as ‘any lesion of the oral mucosa that presents as bright red velvety plaques which cannot be characterized clinically or pathologically as any other recognizable condition’. Erythroplastic lesions are well-defined velvety red plaques and are the oral lesions with the most severe dysplasia and greatest predilection to develop to carcinoma: at least 80% are severely dysplastic or frankly malignant.
Some erythroplakias are associated with white patches, and are then termed speckled leukoplakia or erythroleukoplakia (Table 27.1).
