This case report describes a rare instance of acute appendicitis caused by intraepithelial endometriosis foci in the appendix vermiformis. While fecaliths are the most common cause of luminal obstruction leading to appendicitis, this paper highlights an unusual etiology where endometrial tissue induces blockage. The authors present surgical findings that confirm endometriosis as the underlying pathophysiological mechanism for the acute abdominal presentation. This paper is centrally about endometriosis — specifically illustrating its rare manifestation within the appendix causing acute appendicitis.

2Bursa Military Hospital, Department Of General Surgery, Bursa Abstract Acute appendicitis is the most common cause of acute abdomen. In surgery clinics, appendectomy is still the most frequent urgent surgical procedure. The basic pathophysiology of the acute appendicitis is the luminal obstruction of appendix vermiformis for various reasons. In general, fecaliths are the cause of these obtructions. However, acute appendicitis may occur because of an unusual reason such as intraepithelial endometriosis foci in appendix. 2Bursa Asker Hastanesi, Genel Cerrahi Kliniği, Bursa Akut apandisit, en sık karşılaşılan akut karın nedenidir. Cerrahi klinik pratikte, acil koşullarda en sık yapılan ameliyat hala apendektomidir. Apandisit gelişimindeki temel patofizyoloji, appendix vermiformisin lümeninin çeşitli nedenlerle tıkanmasıdır. Erişkin popülasyonda en sık lümen obstruksiyon nedeni fekalitlerdir. Ancak appendiks epitelinde yerleşen endometriozis odakları gibi sıra dışı bir nedenle de lümen tıkanabilir ve akut apandisit gelişebilir.
