〔Case 1〕 A 69-year-old male. A single 1.8 mm reddish lesion was detected during endoscopic examination following initial EMR in the esophagus five years previously. Magnifying endoscopy revealed characteristic changes of IPCL for carcinoma in situ(IPCL type V-1). The narrow band imaging system(NBI, prototype,Olympus medical systems)is extremely useful to demonstrate capillary changes better. The minute lesion was resected using the EMR-Cap technique. Histological analysis revealed that the resected specimen included a single 1.8 mm carcinoma.

 〔Case 2〕 A 56-year-old male. A 1 mm lesion was observed as a minute flare on the mucosal surface in the middle pharynx. In this case, magnifying endoscopy also clarified proliferation of micro-vessels(IPCL type V-1)in the 1 mm tiny area. Forceps biopsy was carried out to resect the whole lesion as a complete biopsy specimen. The pathological diagnosis for the biopsy specimen was squamous cell carcinoma.
