She had a past history of infertility. Blood investigations were normal and CT scan of abdomen demonstrated findings suggestive of appendicitis. Laparoscopic appendicectomy was performed, which revealed 2 cm tumor-like mass (1.5 cm diameter) present at the tip of appendix involving the mesoappendix. There was no ascites, peritoneal or omental deposits or any signs of inflammation. Post-operative recovery was good. Dissected appendix specimen was sent for histopathological examination which confirmed endometriosis of appendix.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Gastrointestinal endometriosis (GE) accounts for 3\u201337% of all endometriosis cases, whereas AE is present in only \u02dc3% of all GE cases and constitutes &lt;1% of all the endometriosis cases.
