title: An unusual mesenteric paraganglioma producing human chorionic gonadotropin.
abstract: Adrenal and extra-adrenal paragangliomas are uncommon neoplasms arising from the parenchymal cells of paraganglia. The presenting symptoms are mostly due to excess catecholamine secretion. Extra-adrenal paragangliomas are mostly localized in the superior para-aortic region of the abdomen. Mesenteric paragangliomas are very rare. We report an unusual case of mesenteric paraganglioma producing human chorionic gonadotropin (hCG). To the best of our knowledge, this is the first case report describing hCG secretion in an extra-adrenal paraganglioma.
