[Hemoperitoneum caused by leiomyoma of the colon]

The authors report a case of colon leiomyoma revealed by spontaneous hemoperitoneum. This a rare case in which we do not have a gastrointestinal bleeding of the tumor with melena but an endoperitoneal bleeding with hemoperitoneum. Pathologic and clinical aspects of intestinal leiomyomas are discussed, most of them are found in the stomach and only 3% arise in the colon. In this case was also found an histopathological test of a carcinoid of the appendix.
