The tumor adjacent dysplastic epithelium (TADE) that showed loss of fluorescence with the VELscope® is present around the ulcer with the distant clinical normal epithelium (NE) that did not show loss of fluorescence. (B) Photograph of the VELscope® analysis showing the ulcer (arrow) with surrounding TADE with loss of autofluorescence and NE showing normal autofluorescence. (Number of patients screened = 5).
