A Case of Appendiceal Endometriosis Diagnosed as Acute Appendicitis and Treated With Laparoscopic Appendectomy

Year: 2025

Type: article

Abstract: Appendiceal endometriosis is an uncommon manifestation of extrapelvic endometriosis that can clinically and radiologically mimic acute appendicitis. We report the case of a 41-year-old woman who presented with acute right lower quadrant abdominal pain and laboratory findings suggestive of appendicitis. Laparoscopic appendectomy was performed, and histopathology revealed endometrial glands and stroma within the muscularis propria and mesoappendiceal fat, consistent with appendiceal endometriosis. The postoperative course was uneventful, and the patient remained symptom-free at follow-up. This case underscores the necessity of considering appendiceal endometriosis as a rare but potential differential diagnosis of acute abdomen in women of reproductive age and highlights the pivotal role of surgical intervention in both establishing the diagnosis and providing definitive treatment.
