A 46-year-old woman visited a local doctor with dysphagia as her chief complaint and was referred to our hospital for further examination and the treatment of esophageal submucosal tumor. Our endoscopy view showed a longitudinal smooth elevated lesion, 12 cm in size, in the lower esophagus, which was covered with normal mucosa and with a deep depression on the top. Endoscopic urtrasonography showed a hypo-echoic mass located in the submucosal layer. Biopsy specimen taken from the depression showed a malignant lymphoma. The patient underwent surgery, which confirmed the mass to be a primary mucosa-associated lymphoid tissue(MALT)type lymphoma.
