Pedunculated giant gastrointestinal stromal tumor of the stomach showing extragastric growth: report of a case.
We report an unusual case of a pedunculated gastrointestinal stromal tumor (GIST) of the stomach with extragastric growth. An 84-year-old woman was referred to our hospital for investigation of anemia. Barium meal examination showed a defect occupying the lesser curvature of the stomach from the middle of the corpus to the fornix and an abdominal computed tomography scan, showed a lesion, 20 cm in diameter, touching the surface of the spleen. Laparotomy revealed a tumor located between the liver and spleen. As the tumor appeared to be connected with the posterior wall of the gastric corpus by a pedicle, it was resected with a pedunculated lesion of the stomach. Based on the pathological findings, the tumor was diagnosed as a GIST of uncommitted type, with low-grade malignancy.
