Abstract
We studied clinical and histological diagnosis of 22 cases of RLH in the resected stomach. It was difficult to diagnose them as RLH endoscopically. Because we diagnosed only one case as RLH suspicious and 9 cases as early gastric cansers by endoscopic examination. By biopsy findings we diagnosed 6 cases as RLH and one case as RLH suspicious and the diagnostic accuracy of RLH by biopsy was 31.8% (7/22 cases). In the remaining cases, one was diagnosed as malignant lymphoma (ML) and one as ML suspicious by biopsy. Of 5 cases diagnosed as gastric ulcers or gastritis with infiltration of lymphoid and round cells, 2 cases were diagnosed as RLH by repeated biopsy. According to the biopsy sites, we divided the biopsy specimens into 3 groups ; the center, the border and the outside of the lesions and compared them with respect to the biopsy findings. As a result of biopsy findings infiltration of lymphoid and reticular cells was found in 53% at the border, in 40% at the outside and in 38% at the center of the lesions. We concluded that it is important for the definite diagnosis of RLH of the stomach to obtain biopsy specimens from the border of a lesion.
