title: [Gangliocytic paraganglioma of the ampulla of Vater].
abstract: A case of a bleeding duodenal gangliocytic paraganglioma (GPG) of the Papilla Vateri is reported. The 47 year old patient was treated successfully by partial pancreaticoduodenectomy. Histologically the GPG is characterized by three types of cells: epitheloid cells, ganglion-like cells and spindle cells. So far 81 cases are reported in the literature. Most cases of GPGs are benign, metastasis or recurrence is possible. This case showed an infiltrative growth pattern indicating the true neoplastic nature of this tumor.
