This paper reports a case of a 40-year-old woman who presented with acute perforated appendicitis, later found to have appendiceal endometriosis on postoperative histopathologic examination. The authors discuss that appendiceal endometriotic lesions account for less than 1% of pelvic endometriosis and may mimic acute appendicitis, making diagnosis preoperatively challenging. A limitation is that, as a single case report with literature review, the evidence base is not generalizable beyond documented presentations and cannot establish causality or incidence. This paper is centrally about endometriosis — specifically appendiceal endometriosis presenting as perforated appendicitis.

Abstract

While endometriosis is a common disorder in women of reproductive age, appendiceal endometriosis accounts for less than 1% of all pelvic endometriotic lesions. Involvement at this site may present as acute appendicitis and be diagnosed only upon postoperative histopathologic examination. We report such an occurrence of appendiceal endometriosis in a 40-year-old woman who presented with acute perforated appendicitis.
