Gastric malignant lymphoma is a rare disease. Early gastric lymphoma of surface type is particularly difficult to determine operative indication because of difficulty in differentiating malignant lymphoma from benign diseases such as gastric ulcer and reactive lymphoreticular hyperplasia (RLH). We experienced a case of early gastric malignant lymphoma that underwent curative operation because we suspected malignant disease from features of gastrofiberscopic and double contrast roentgenographic findings, though histological diagnoses from biopsy specimen were benign several times. The patient was a 59-year-old man. His chief complaints were hematemesis and abdominal pain. He had been treated at a nearby hospital with the diagnosis of gastric ulcer for eight months and was admitted to our hospital because of hematemesis at night. Histological diagnoses from gastrofiberscopic biopsies were Group j at first time and Group II at second time, but he was operated on because early gastric cancer of type II c was suspected by macroscopic findings. The pathohistological diagnosis was non-Hodgikin lymphoma. The infiltrating grade was sm. Lymph nodes metastasis was not seen. The histological staging was stage IE. It is more difficult to diagnose gastric lymphoma than gastric cancer. In particular, the diagnosis of early gastric lymphoma is needed with special emphasis on macroscopic features and complaints.
