Duodenal leiomyosarcoma

Two cases of duodenal leiomyosarcoma were encountered, both of which appeared benign by gross and histologic criteria. Both patients suffered recurrences with poor outcomes. We reviewed the literature and found four other such cases and examined the outcomes in the world literature with respect to tumor size and extent of surgical resection. Large size, limited resections, and local recurrence were associated with poor outcomes. A 6% rate of lymphatic metastases was found, and the bearing this has on the extent of resection is discussed.
