Leiomyosarcoma of the duodenum

Leiomyosarcoma of the duodenum is a rare tumor. These tumors manifest with unexplained melena, anemia and sometimes partial duodenal obstruction. Diagnosis is difficult on account of inaccessibility for biopsy. Treatment involves excision of the duodenum with reconstruction, a difficult task with high morbidity and mortality. However, if the tumor is successfully treated, its prognosis is usually good because of its non-aggressive nature.
