title: [Extrahepatic gastrinoma. Report of a clinical case].
abstract: Gastrinoma is a rare neoplasia producing gastrina, the hormone responsible of the clinic manifestations related to Zollinger-Ellison syndrome. The localization of gastrinoma is pancreatic or extrapancreatic (usually in Stabile and Passaro triangle). We present a case report concerning an extra-pancreatic gastrinoma not localized in this area and included in a lymph node. This is an extremely infrequent localization (2.4%). There are two different opinions about this localization. Some authors think that this is always a secondary lesion of a small primary neoplasia usually asymptomatic. Other authors think that there are primary lymph nodal gastrinomas that could be safely removed with excision of lymph node. The infrequent localisation of this case induced us to report this experience in order to contribute to the comprehension of this pathology.
