 An ultra tiny SCC is defined as a tumor 5mm or less in size. The endoscopic finding of ultra tiny SCC is a flat red spot. The background mucosa looks red under white-light endoscopy. Therefore, the contrast between SCC and background mucosa is small. However, NBI endoscopy reveals SCC as a red brown area, and the contrast becomes clearer. Therefore, NBI is useful for the detection of ultra tiny esophageal SCC. Iodine staining is the most sensitive method to detect an ultra tiny SCC. However, the patient feels discomfort and the surface of SCC degenerates and is covered by non-neoplastic mucosa. Sometimes, the detection by iodine becomes difficult. Therefore, it might be more suitable to detect ultra tiny SCC by WL or NBI, rather than using iodine staining.
