Its location in the duodenum makes diagnosis difficult and often delayed. Surgical treatment is not consensual because it must take into account anatomical imperatives which vary depending on the duodenal portion and oncological requirements that are not currently well known especially with regard to the utility of lymphadenectomy. We report 2 cases of leiomyosarcomas located at the angle of Treitz. This location is exceptional and only few cases were reported in the literature. From these 2 new cases and a review of the literature, we analyze the clinical features, diagnosis and treatment of duodenal leiomyosarcoma.展开更多
