Endometriosis is the implantation of endometrial glands and stroma outside the uterus.\nCase report\nWe here report the coexistence of carcinoid tumor of appendix and ileal endometriosis in a 37-year-old nulliparous woman who came to the emergency room with right lower abdominal pain mimicking acute appendicitis. The main clinical and laboratory findings included fever, leukocytosis and elevated ESR. With preoperative suspicion of acute appendicitis, laparatomy was performed and revealed apparently normal looking appendix, along with a nodule in the terminal ileum. Both the appendix and ileal nodule were removed. Histological examinations revealed carcinoid tumor of appendix and ileal endometriosis. The case was discharged 4 days after surgery with no pain and symptoms and remained symptom free for the 1 year period of follow up.\nConclusion\nMany cases of carcinoid tumor of the appendix and ileal endometriosis are diagnosed incidentally. Overall prognosis of these conditions is very good. Surgical treatment seems to be the best intervention for these disorders.\nSimilar content being viewed by others\nReferences\nAddiss DG, Shaffer N, Fowler BS, Tauxe RV (1990) The epidemiology of appendicitis and appendectomy in the United States.
