Question: A 56-year-old woman was referred to our hospital and presented with heartburn. The patient had a history of cholecystectomy, but denied any systemic symptoms. Upon physical examination, the liver, spleen, and superficial lymph nodes were not palpable. Laboratory studies showed no abnormalities. Endoscopic examination revealed a flat lesion spanning longitudinally of the esophagus 30-36 cm from the incisor teeth with a rough surface (Figure A), slightly stained by Lugol chromoendoscopy (Figure B). Endoscopic ultrasonography showed an inhomogenous hyperechoic lesion with hypoechoic zone centrally (Figure C). Twice endoscopic specimens obtained by biopsy forceps did not demonstrate any notable abnormal findings, except some lymphocytes. Chest computed tomography did not reveal remarkable abnormal- ities. Endoscopic submucosal dissection was performed. What is the most likely diagnosis?
