Summary: Meckel‘s diverticulum is not a common cause of lower intestinal bleeding in the adult. A tumor arising in the diverticulum is a much less common cause of bleeding. Leiomyosarcomas represent 10-20 % of malignant tumors in the small bowel and 1 % of those located in the large bowel. These tumors have a specific symptoms depending on their size, location and histology. Intestinal leiomyosarcomas may be the cause of numerous types of surgical emergency. We describe the case of an adult male with acute painless intestinal bleeding, the cause of which was a leiomyosarcom arising in a diverticulum Meckeli. It was diagnosed during an emergency exploratory celiotomy. The main cause of surgical emergency was an extremly rare complication of gastrointestinal leiomyosarcoma -intestinal bleeding.
