Abstract

The gastrointestinal tract is the most common extranodal site for lymphomas, and mucosa-associated lymphoid tissue lymphoma is the second most common histological lymphoma subtype. However, primary esophageal mucosa-associated lymphoid tissue lymphomas are extremely rare. Few such cases are documented, and the reports demonstrate inconsistent diagnostic and therapeutic strategies. Herein, a 54-year-old man was referred to our hospital for treatment of dysphagia. Esophagogastroduodenoscopy revealed a large, horseshoe-shaped subepithelial mass in the upper esophagus. Endoscopic ultrasonography and computed tomography revealed that the mass was well-demarcated and confined to the muscularis mucosa, with no abnormalities in other organs or lymph nodes. The mass was presumptively diagnosed as benign, and the patient underwent endoscopic mucosal dissection for pathological confirmation and symptom relief. Pathological examination of the dissection specimen revealed that it was a primary esophageal mucosa-associated lymphoid tissue lymphoma. As the patient had an elevated immunoglobulin G level and Helicobacter pylori infection, we administered adjuvant eradication therapy. The patient remains under surveillance and is free of lymphoma recurrence 36 months postoperatively. This case report demonstrates that endoscopic resection and H. pylori eradication are effective treatment strategies for early-stage esophageal mucosa-associated lymphoid tissue lymphoma.
