A Long Survival Case of Carcinoid Tumor of the Gallbladder

Our long survival case is aggressive neoplasm, despite the histological diagnosis as carcinoid of the gallbladder. Case: A 61-year-old woman with right upper quadrant pain was found in ultrasonography (US) and computed tomography (CT) to have a tumor surrounding the gallbladder. Under a preoperative diagnosis of gallbladder adenocarcinoma, we conduced right liver lobectomy of the liver. Microscopically, the tumor showed a carcinoid tumor consisting of nests of small oval cells with round to oval nuclei. Tumor cells were positive for Grimelius'stain. Immunohistochemically, these cells were positive for chromoganinA. Although hepatic metastasis, right renal metastasis, abdominal paraaortic lymph node metastasis, and right adrenal metastasis were detected after the operation, aggressive therapy led to 81 months (6.5 years) of survival.
