Gastrointestinal stromal tumors (GISTs) of the gallbladder are representative of an extremely rare group of tumors. We have encountered a patient with a malignant GIST of the gallbladder and presented it with a review of some articles. A 72-yr-old woman initially presented with right upper quadrant abdominal pain, fever and chills. Emergency cholecystectomy was performed under the impression of gallbladder empyema. Liver metastasis was found at 7 months postoperatively and the patient expired 9 months after the surgery. At the time of cholecystectomy, the gallbladder showed a necrotic serosal surface with an irregular thickened wall. A mass, 6 cm in length and 3 cm in width, encircled the whole wall of the neck and upper body of the gallbladder. Microscopic findings revealed frequent mitotic figures (more than 20/50 HPF) and tumor necrosis. Hyperchromatic, pleomorphic and spindle shaped neoplastic cells that were arranged in a pattern of short fascicles infiltrated the entire layer of the gallbladder. The tumor cells were immunoreactive for CD117 antigen (c-kit protein) and vimentin. They were negative for desmin, smooth muscle actin and S-100 protein. Mutations of the c-kit proto-oncogene were not found in this case. These findings were sufficient to provide enough clinical, histopathological and immunohistochemical evidence in diagnosing our case as a malignant GIST.

Gastrointestinal stromal tumor (GIST) is an uncommon mesenchymal tumor of the gastrointestinal tract and is generally located in the stomach and small intestine. They usually present with abdominal pain, gastrointestinal bleeding, and palpable mass. Some patients present with rare symptoms that are more common in malignant GIST. Malignant GIST combined with a liver abscess has not been reported yet in the literatures. We report a case of 67-year-old woman who suffered from liver abscess combined by malignant GIST with central necrosis and fistula in the ileum. She complained of fever, chills, and abdominal pain. Abdominal CT scan showed huge liver abscess and ileal mass with air pocket. Small bowel series showed contrast material filling into the ileal GIST mass. An operation was performed and the final diagnosis was malignant GIST of the ileum with invasion into the sigmoid colon and urinary bladder.
