Gastrointestinal endometriosis is observed in 3\u201337% of all endometriosis cases, whereas appendiceal endometriosis accounts for only about 3% of gastrointestinal endometriosis. Appendiceal endometriosis is usually asymptomatic, although it sometimes causes abdominal cramps, nausea, chronic pelvic pain, lower gastrointestinal hemorrhage, intussusception, perforation, or acute appendicitis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>Appendiceal endometriosis is an unusual histopathological finding. A preoperative diagnosis is difficult, but this condition should be considered when women of childbearing age present with clinical symptoms of acute appendicitis.<\/jats:p>\n
