title: Gallbladder paraganglioma: a case report with review of the literature.
abstract: We report a case of gallbladder paraganglioma that was discovered during nonrelated surgery. Retrospective study disclosed a family history of pheochromocytoma. The occurrence of gallbladder paraganglioma in the presence of family history of endocrine neoplasia supports that gallbladder paraganglioma may indeed occur as a part of the multiple endocrine neoplasm syndrome. Gallbladder paraganglioma is a rare tumor, and so far to our knowledge only 6 cases have been reported in the literature. Three cases were discovered incidentally during cholecystectomy for cholelithiasis, 2 presented with right upper quadrant pain, and 1 manifested with gastrointestinal bleeding. We herein review all reported cases of paraganglioma of gallbladder and biliary system.
