title: [Gastrointestinal stromal tumor metastasized to the ovary].
abstract: Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract, is originated from the interstitial cells of Cajal. As a sign of malignancy, intestinal tumors particularly tend to metastasize, primarily in the abdominal cavity and in the liver. The authors present a gastrointestinal stromal tumor of the intestine, which metastasized to the ovary. The tumor presented as a pelvic mass, mimicking an ovarian neoplasm. In the case of clinically simultaneous tumors of the gastrointestinal tract and of the ovary, one has to consider the possibility of a primary gastrointestinal tumor and first of all a gastrointestinal stromal tumor. The histological diagnosis is essential because of the tumor-specific chemotherapeutical opportunity of gastrointestinal stromal tumors.
