title: Extremely rare case of primary esophageal mucous associated lymphoid tissue lymphoma.
abstract: SJ is a 37-year-old male who presented with one year history of dysphagia, odynophagia and 15 pounds weight loss. He underwent endoscopic evaluation which showed mid esophageal ulcers. It was thought that the cause of the ulcer was the multivitamins and the patient was asked to stop them. Furthermore Esomeprazole therapy was also initiated. Patient's symptoms persisted but he did not seek any medical attention until about one year later. Meanwhile the patient reported additional 15 pounds of weight loss. We repeated upper endoscopy again which showed evidence of two chronic non bleeding irregular friable ulcerations seen in the mid esophagus, 31 cm from the incisors. Biopsies and frozen section were taken and sent for assessment to the Pathology lab. Immunoperoxidase studies on frozen sections showed the presence of IgM and for most plasma cells IgG. The microscopic and histologic findings were consistent with mucous associated lymphoid tissue lymphoma with plasmocytic differentiation. Computed tomographic scan done showed no evidence of spread to adjacent structures. The patient was referred to oncology and several cycles of radiation and Rituximab therapy were initiated which cured the disease. Subsequent endoscopies with blind biopsies were done which were negative for any neoplastic process.
