Abstract

Reported herein is the case of a 80-year-old man who had small squamous cell carcinoma in the esophagus.The lesion was initially detected as a irregular reddish elevated and flat area depicted by non-magnified white light endoscopy and observed as a brownish area with the narrow-band imaging system (NBI). The depth of elevated and depressed area in the lesion was predicted to be LSM to MM due to Inoue's classification of morphologic change of intrapapillary capillary loop (IPCL) under magnified NBI observation. The depth of another flat area was not able to predicted by Inoue's classification, and we used Arima's classification. We predicted the depth of invasion to beMMto SM1.by this classification. Endoscopic submucosal dissection (ESD) was carried out for the lesion.As a result, the endoscopic diagnosis completely accorded with pathological diagnosis.We could diagnose correctly by adding Arima's classification to Inoue's classification.
