Surgical management of pancreatic lymphoma.
The clinical and pathologic records of 12 patients with pancreatic lymphoma were reviewed retrospectively to determine distinguishing clinical features. Radiologically, all patients had large abdominal masses in the region of the pancreas. Preoperative percutaneous cytologic biopsy specimens failed to make the diagnosis, and two specimens were interpreted incorrectly as poorly differentiated adenocarcinoma. The diagnosis was difficult to make in two cases, even at laparotomy. Four patients underwent a biliary bypass, and two underwent a concomitant gastric or duodenal bypass. Two patients died postoperatively. Four patients responded well to chemotherapy and/or radiation therapy, and two did not have any recurrences at 3 and 7 years postoperatively. Although rare, lymphoma should be considered in patients with undiagnosed pancreatic masses. The diagnosis may only be made with appropriate preoperative or intraoperative suspicion, and treatment may be rewarding, particularly in comparison with pancreatic adenocarcinoma.
