The physical and clinical assessment referred for laboratory, the findings suggested acute appendicitis, then admitted to Baghdad teaching hospital for Laparoscopic appendectomy, and the specimen was sent for histopathological examination, where it revealed endometrial glands and stroma embedded in the muscularis propria of the appendix.\nConclusion: Although rare, appendiceal endometriosis should be considered in the differential diagnosis of RLQ pain in reproductive-age women. This case indicates the necessity of routine histopathological examination of all appendectomy specimens to ensure accurate diagnosis and appropriate follow-up.\nReceived: 23 Jan. 2026,\nRevised:13 May 2026,\nAccepted: 20 May 2026,\nPublished Online: July 2026\nPublished: 01 July 2026\nDownloads\nReferences\nParasar P, Ozcan P, Terry KL.
