title: [Carcinoid tumor of the ampulla of Vater. Morphology, diagnosis and therapy of a rare papilla tumor].
abstract: We report on a patient with a carcinoid tumour of the ampulla of Vater and review the 33 known cases of the literature with regard to clinical presentation, morphology and therapy. As it is apparent from the location of the tumour, obstructive jaundice, pancreatitis and nonspecific upper abdominal complaints are the most frequent symptoms. The ampullary carcinoid belongs histogenetically to the APUD cell system with the ability of multiple endocrine activity. The expression of somatostatin peptide and neuron-specific enolase are the most common histopathological findings. A systemic function of these hormones, however, has not yet been shown. For diagnostic purposes in surgical pathology we found synaptophysin and chromogranin A to be important markers. For surgical treatment, partial duodenopancreatectomy remains the current therapy of choise, if the tumour exceeds two centimeters in diameter.
