This paper reports two cases of appendiceal endometriosis, described as occurring in patients operated on with a prediagnosis of acute appendicitis. The authors note that appendiceal endometriosis is rare (reported incidence lower than 1% among pathologies of pelvic endometriosis) and can present with acute or sometimes asymptomatic findings such as intussusception, colic, or melena, but diagnosis in these cases was only made postoperatively by histopathology. A key limitation is that the evidence is limited to case reports without broader diagnostic or incidence assessment. This paper is centrally about endometriosis — it presents two cases specifically of appendiceal endometriosis and discusses its typical presentations and reliance on histopathology for diagnosis.

Abstract

The incidence of appendiceal endometriosis is lower than 1% among pathologies of pelvic endometriosis. They may occur with findings such as acute appendicitis, invagination, colic or melena, though they are mostly seen with an asymptomatic character. Diagnosis can be made only after a histopathological examination following the operation. We present here two appendiceal endometriosis cases, which were operated on for a prediagnosis of acute appendicitis, but postoperatively diagnosed as appendiceal endometriosis.
