Summary. A 69‐year‐old man presented with right neck tumour. Primary thyroid MALT lymphoma occurring in Hasimoto's thyroiditis was diagnosed. He was also diagnosed to have gastric cancer with Helicobacter pylori infection. After subtotal gastrectomy by itself, thyroid lymphoma became smaller transiently. Then the patient was treated with H. pylori eradication therapy, resulting in the complete disappearance of lymphoma. Although H. pylori organisms were not detected in the lymphoma tissue by polymerase chain reaction (PCR), it might be implicated in the pathogenesis of extragastric MALT lymphomas.
