Thirty eight cases of primary gastric malignant lymphoma were studied morphologically and immunohistochemically. The Working Formulation was used for classification of non‐Hodgkin's lymphoma (1). The results indicated that 37 cases were non‐Hodgkin's lymphoma while the remaining case was Hodgkin's disease. Thirty‐three cases (89%) of non Hodgkin's lymphoma were considered to be of B cell origin and 2 cases (5%) of histiocytic origin. No case was considered to be of T cell origin. We suggest that the majority of primary gastric malignant lymphomas are derived from follicular center cells, and that gastric plas‐macytoma is not as rare as previously described.
