 A man in his 60s undergoing conventional esophagoscopy for surveillance was found to have a deeply depressed lesion(7mm)with marginal elevation. After observation with insufficient air supply, the lesion had no vertical fold and a firm consistently because of the loss of change in form. Narrow-band imaging with magnification of the depressed area revealed Type B2 microvessels throughout, and endoscopic ultrasound showed that the low echoic lesion extended around the muscular layers, suggesting a massive invasion of the submucosal layer. ESD(endoscopic submucosal dissection)followed by CRT(chemoradiotherapy)was planned according to the study protocols(study ID JCOG0508). Histopathology revealed poorly differentiated squamous cell carcinoma with massive submucosal invasion, infiltrative growth pattern, and lymphovascular involvement. Immunohistochemistry showed diffuse cytokeratin 7. Although additional CRT was applied(RT 40 Gy including Long T field, FP 2 course), multiple lymph node metastases in the radiotherapy field occurred 8 months after CRT. The patient died of primary cancer at 22 months after ESD despite additional chemotherapy.
