Abstract
A case of leiomyosarcoma of Meckel's diverticulum accompanied by intra-peritoneal bleeding is reported because of its rarity in the literature. The patient, a 75-year-old man who was admitted to our hospital for diabetes mellitus, suddenly complained of vomiting. Physical examination showed anemia and very low blood pressure (60mmHg). Intra-peritoneal bleeding was found by ultrasonography and abdominal puncture. A ruptured soft tumor, 6 × 6 cm in size, was present at the tip of Meckel's diverticulum which was found about 80 cm proximal to Bauhin's valve at surgery. About 1000 ml of bloody ascitic fluid was seen in the peritoneal cavity. Partial resection of the ileum and peritoneal lavage were performed. histological examination revealed diffuse growth of atypical spindle cells with nuclear variation, and a diagnosis of leiomyosarcoma was made.
