25 Carcinoid Tumor Cases Incidentally Detected After 4642 Appendectomies

Aim: This study aimed to retrospectively investigate 25 cases of carcinoid tumors in 4642 pathological examinations of patients who admitted to our clinic with acute appendicitis in a period of 6 years. Method: 4642 appendectomy operations performed in Şanlıurfa Training and Research Hospital and Mehmet Akif İnan Training and Research Hospital between 2012 and 2019 were evaluated retrospectively. Data regarding age, sex, preoperative clinical findings, histopathological results, operation reports, follow-up period, and metastasis status were extracted from electronic records and reported. Results: Based on the histopathological examination of 4642 patients admitted to the emergency department of two large hospitals of Şanlıurfa province, 25 patients were diagnosed with carcinoid tumors (neuroendocrine tumor). Thirteen of our patients were male and 12 of them were female. The mean age of our patients was 33.2 years. The mean follow-up period was 5-62 months. No distant metastasis was detected in any of the follow-ups of our patients who had histopathologically well-differentiated carcinoid tumors. Conclusion: Carcinoid tumors are the most common tumors of the appendix, which are detected incidentally after an acute appendicitis operation. Since these tumors are rare, histopathological evaluation and postoperative follow-up are important. Though, in our study, it is not common in terms of rate, it is still important to follow up these cases since it is common in the young population, and there is a possibility of metastasis in advanced stages.
