MUSCULAR TUMORS OF GASTROINTESTINAL-TRACT

We report the experience of the General Surgery Service of Segovia General Hospital. In a 15-years-period (1976-1991), we have cared for 32 patients with muscular tumors of the gastrointestinal tract, including 22 leiomyomas and 11 leiomyosarcomas. These tumors were localized in stomach (46.8%), small intestine (40.6%), esophagus (9.3%) and colon-rectum (3.1%). A histologic study was developed on the basis of the mitosis number in 10 high power fields. Clinical manifestations, histological dates, treatment, and prognosis factors, outstanding the histological grade, size lesser than 10 cm, and tumor origin localization, are reviewed.
