title: Primary malignant lymphoma of the spleen.
abstract: We treated two patients with primary splenic malignant lymphoma. One was a 63-year-old man with diffuse histiocytic non-Hodgkin's lymphoma accompanied by multiple liver metastases which were composed of necrotic tissue probably due to preoperative transarterial chemoembolization (TAE). He eventually died of liver failure two years and six months after splenectomy. The autopsy revealed that a large part of the cirrhotic liver had been occupied by a diffuse-type hepatocellular carcinoma, but no recurrence of the malignant lymphoma was found in the liver or other organs. The second patient was a 40-year-old woman with a massive invasion of the stomach, colon, pancreas, and diaphragm by a splenic tumor. The splenic tumor and the adjacent involved organs were resected. Pathologically, well-differentiated diffuse lymphocytic non-Hodgkin's malignant lymphoma was evident. No recurrence has been found for six years and two months. Based on an evaluation of the 71 patients with primary splenic malignant lymphoma reported to data in Japan, the patients treated by a curative resection in an early clinical stage have a more favorable prognosis.
