We report a rare case of a @entity356 treated with endoscopic resection and oral @entity2816 therapy. A 70-year-old @entity1 was admitted to our hospital with indigestion. He had no specific medical history and unremarkable laboratory results. Gastroendoscopic findings revealed a focal, erythematous, flat elevated lesion in the anterior wall of the stomach antrum. A biopsy revealed atypical lymphocytes. Endoscopic submucosal dissection (ESD) with an insulation-tipped knife was performed 45 days after diagnosis. Radiological and hematological evaluations, including a bone marrow biopsy, were performed and showed no involvement of other organs. The @entity1 was diagnosed with extramedullary @entity356 . Follow-up gastroendoscopy was performed three times during a 2-year period and showed nonspecific ESD scarring. The @entity1 's condition was found to be stable.
