A 55-year-old woman with a small focus of malignant lymphoma, 6 mm in diameter, arising within an area of reactive lymphoid hyperplasia (RLH) of the stomach is reported. The diagnosis of lymphoma was suspected by the preoperative endoscopic biopsy. This is the case of this association with an unusually small lymphoma in the early stage, in support of the view that there may be an intimate histogenetic relationship between lymphoma and RLH.
