Leiomyosarcomas of the mesentery1

SUMMARY We report on three cases of leiomyosarcoma of the mesentery, which were treated in our department during the period 1990-1999. They were two men and one woman aged from 50-82 years. All three patients presented with gradual weight loss and palpable abdominal mass. In addition, one patient developed a subileus symptomatology. In two cases the tumor was situated at the mesentery of the terminal ileum and in one case at the mesentery of the jejunum. The diameter of the tumors ranged between 5-12cm. No intraperitoneal spread of the tumor was found. All patients underwent curative resection of the tumor and the adjacent part of the small intestine (16-40 cm). All patients remain free of disease, 3months – 10 years after the operation. Key words: leiomyosarcomas – GIST - mesentery
