  • Abstract
  • Look Inside

 Esophageal dysplasia which is not detected by conventional endoscopic examination is recognized only by iodine staining exhibiting as an unstained or faintly stained area. Some dysplastic lesions can be seen as a slightly elevated white area or faintly reddish one. It is possible to estimate the severity of dysplasia based on the degree of iodine staining. Severe dysplasia is shown as a white area with a clear margin and moderate or mild dysplasia as faintly stained area with spotty or linear brown segments. When dysplastic lesions are discovered in the esophagus, meticulous follow-up endoscopy with iodine staining should be performed. For the lesions which have increased in size or in severity, an endoscopic mucosectomy should be performed to make a correct diagnosis leading to an adequate treatment.
