title: Gallbladder paraganglioma.
abstract: Gallbladder paraganglioma is a very rare tumor, and only a few cases have been reported. Most of these cases were asymptomatic and found incidentally during operation. Our case involved a 57-year-old female patient complaining of intermittent right upper quadrant pain. Preoperative imaging demonstrated a mass in the neck of the gallbladder. Laparoscopic cholecystectomy was performed, and a frozen section of the gallbladder demonstrated a benign mass. The postoperative pathologic examination reported gallbladder paraganglioma and chronic cholecystitis. Immunohistochemically, the chief cells and sustentacular cells showed diffuse positivity with vimentin, synaptophysin, and S-100.
