title: A case of retroperitoneal lymphoma presenting as pancreatic tumor.
abstract: We describe a case of non-Hodgkin's lymphoma arising in the peripancreatic retroperitoneal lymph node and extending into the pancreatic parenchyma. Abdominal ultrasonogram and computed tomography of the abdomen showed an mass in the head of pancreas with absence of extrapancreatic disease and no direct tumor extension to the portal vein or superior mesenteric artery. Laparotomy demonstrated a large pancreatic mass with no obstruction of common bile duct or encasement of portal vein and superior mesenteric artery and a pancreaticoduodenectomy was performed. He received chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone. The patient is alive and in remission with a follow-up time of 24 months.
