Appendiceal Endometriosis: A Rare Cause of Acute Appendicitis
Background: Acute appendicitis is the most common cause of acute abdomen. The etiology has not been defined clearly but potential causes are fecoliths, lymphoid hyperplasia and malignancies. However, an extremely uncommon cause of acute appendicitis is endometriosis which leads to dilemmas in the diagnostic process. Case report: A 21-year-old Caucasian female patient presented in the Emergency department complaining of acute progressive abdominal pain in the right lower quadrant. The physical examination revealed signs consistent with acute appendicitis. The patient underwent diagnostic laparoscopy, which revealed early inflammation of the appendix and thus was subjected to appendicectomy. Histologic examination revealed endometriosis of the appendix. Conclusion: The presented case emphasizes on how endometriosis can affect only the appendix without any involvement of the reproductive organs. A high index of clinical suspicion is required especially in women of reproductive age who present with periodic chronic pain associated with their menstrual cycle. Nonetheless, this can only be confirmed through diagnostic laparoscopy and histologic examination, which also provides the definite cure of the disease.
