EnglishGastrointestinal leiomyosarcoma is a rare neoplasm, the stomach being the most frequent site of settlement, followed by the small intestine (ileum). Only 3% of cases affect the colon. In the latter case, a differential diagnosis would have to be made, fundamentally with colon adenocarcinoma.
