[Leiomyosarcoma of the small intestine presenting as an isolated lower digestive tract hemorrhage. Report of 2 cases]. / Léiomyosarcome du grêle révélé par une hémorragie digestive basse isolée. A propos de deux cas.

The authors report two cases of leiomyosarcoma of the small intestine revealed by lower and isolated digestive bleeding. In both cases, only the pelvic examinations by means of ultrasonography and/or CT scan have shown a mass which corresponded to the small intestine tumor. The authors underlined the necessity of US and/or CT scan pelvic when faced with a lower digestive bleeding whose etiology cannot be determined by the endoscopic or radiologic intestinal examinations.
