Abstract
A 44-year-old male patient was admitted to the hospital in March, 1980, complaining of a massive splenomegaly and was diagnosed to have non-Hodkin's lymphoma around the spleen, based on the pathological findings on laparotomy. He received BACOP chemotherapy with a marked improvement. However, there appeared another cystic mass in the upper abdomen during the treatment, which was suspected to be a pancreatic pseudocyst. Fortunately, it became smaller with the ordinary BACOP chemotherapy. After a successful treatment, he had been followed as an outpatient. In March, 1980 he was readmitted to he hospital, complaining of splenomegaly and systemic lymphnode swelling. In June, 1980 he died of systemic infiltration of malignat lymphoma despite an intensive chemotherapy and radiotherapy. At autopsy there was a large, necrotic lumen behind stomach, which involved spleen, pancreas, duodenum, and left-diaphragm. The inner wall of the lumen consisted of necrotic tissue of malignant lymphoma. There was no pancreatic pseudocyst in malignant lymphoma.
