ABSTRACT

Gastrointestinal stromal tumor (GIST) of ileum is a rare tumor of gastrointestial tract that arise from primitive mesenchymal cells. GIST occur predominantly in persons over 40 years of age with an equal sex incidence. GIST expresses a heterogenous clinical course and the most important prognostic factors are tumor size, site, degree of mitotic activity, tumor necrosis. We report a case of GIST of ileum, which was misdiagnosed as extrauterine leiomyoma preoperatively.
