title: [Leiomyosarcoma of Meckel's diverticulum--a rare cause of acute hemorrhage in the lower part of the digestive system].
abstract: Meckel's diverticulum is a rare cause of haemorrhage into digestive tract in adults. A tumour arising in the diverticulum is also a rare cause of bleeding. Leiomyosarcomas represent 10-20% of malignant tumours in the small bowel and 1% of those located in the large bowel. These tumours have non-specific symptoms depending on their size, location and histology. Intestinal leiomyosarcomas may be the cause of surgical emergencies. We describe the case of an adult male with acute painless intestinal bleeding the cause of which was a leiomyosarcoma arising in Meckel's diverticulum. It was diagnosed during an acute operation. The main cause of the surgical emergency was an extremely rare complication of gastrointestinal leiomyosarcoma--intestinal bleeding.
