We report two cases of malignant lymphoma (ML) of the stomach which had an interesting clinical course. In case 1, the patient was a 68-year-old woman who had been followed for 2 years and 9 months under the diagnoses of multiple gastric ulcer and reactive lymphoreticular hyperplasia (RLH). Although the histological diagnosis by endoscopic biopsy was RLH, we clinically suspected ML, and she underwent total gastrectomy. This case shows the difficulty in making a differential diagnosis between ML and RLH even with biopsy examination and suggests the possibility of a change from RLH to ML. The patient in case 2 was a 71-year-old woman who had undergone subtotal gastorectomy 4 years earlier for ML of the stomach, which appeared to be Borrmann 2 type. As the present X-ray and endoscopic examination suggested recurrence of ML in the remnant stomach and this was confirmed by biopsy, total resection of the remnant stomach was carried out. This is the fifth case of the recurrent ML of the remnant stomach reported in Japan.
