Abstract

|
Mucosa-associated lymphoid tissue (MALT) lymphoma is found in various organs as extranodal B cell lymphoma. The gastrointestinal tract is the most commonly involved extranodal site in MALT lymphoma. However, primary esophageal MALT lymphoma is very rare. In addition, few cases with metachronous gastric involvement have been reported. A 55-year-old man was diagnosed with MALT lymphoma by surveillance esophagogastroduodenoscopy. A 5 cm esophageal submucosal tumor-like lesion was incidentally revealed by screening esophagogastroduodenoscopy two years prior. Esophagogastroduodenoscopy showed a cylindrically elongated submucosal mass with normal overlying mucosa in the mid esophagus. He underwent surgery to confirm the diagnosis. The pathologic diagnosis was esophageal MALT lymphoma. He was treated with radiation, which achieved complete remission. Esophagogastroduodenoscopy and chest computed tomography were performed every three to six months, with no evidence of recurrence for 18 months. After 21 months, several elevated gastric erosions were found on the great curvature and posterior sides of the midbody and confirmed as MALT lymphoma pathologically. Here we report a case with MALT lymphoma metachronously involving the esophagus and stomach.
