Eight patients with von Recklinghausen's disease (VRD) and duodenal carcinoids are presented. Seven patients were black, and one white. Six of the eight were women. The presenting symptom was either jaundice or abdominal pain. All tumors were located in the second portion of the duodenum, and three were multiple. Associated tumors other than neurofibromas included multiple leiomyomas, meningioma, neurofibrosarcoma, and prostatic sarcoma. Seven tumors had psammoma bodies, and in three they were numerous. Somatostatin-positive cells were demonstrated in all cases. Two tumors had spread to regional lymph nodes at the time of surgery. There appears to be a predilection for black patients among those with VRD and duodenal carcinoids.

Sixteen primary pancreatic tumors were found in a retrospective study of bovine pancreatic lesions detected in slaughtered cattle. Eleven islet cell tumors and three pancreatic exocrine carcinomas were identified based on light microscopy and immunohistochemistry. Nine of 11 islet cell tumors were classified as malignant. Metastatic sites included iliac, mediastinal, hepatic, and mesenteric lymph nodes, peritoneum, mesentery, and liver. Six cows with multiple islet cell tumors also had pheochromocytomas. All 11 islet cell tumors had positive immunoreactivity to insulin and somatostatin. Three tumors also contained cells immunoreactive for glucagon and two tumors contained pancreatic polypeptide immunoreactive cells. Immunoreactivity of tumor cells in metastatic sites was similar to their respective primary tumors. All exocrine pancreatic carcinomas metastasized widely and were immunonegative for insulin, somatostatin, glucagon, and pancreatic polypeptide. No mixed endocrine-exocrine tumors were identified. None of the endocrine or exocrine tumors contained amyloid. Additional primary tumors of the bovine pancreas included one neurofibroma and one neurofibrosarcoma. Additional cases with lesions of the bovine pancreas included nodular hyperplasia in 15 cows, exocrine acinar atrophy and fibrosis in four cows (two of which also had pancreatic lithiasis), pancreatitis in one cow, peripancreatic fibrosis in two cows, pancreatic steatosis in one animal, and pancreatic hemorrhages in one cow.
