[Extrauterine endometriosis: three new cases].

Extragonadal endometriosis is rarely diagnosed preoperatively due the variety of its localizations. Presentation to general surgeons may be atypical and pose diagnostic difficulties. The Authors report three cases surgically treated between 2000-2003. The Authors stress the peculiarity of one of these cases with endometrial tissue involvement of the intestinal mucosa. They also discuss about various aetiological hypothesis, symptomatology, differential diagnosis and need for multidisciplinary treatment.
