Appendiceal neuroendocrine tumors (ANETs) are the most common in the appendix, detected in histopathological appendectomy specimens, which are resected for acute appendicitis. If tumor detection does not show signs of metastatic disease or obvious features of carcinoid syndrome, preoperative diagnosis remains a challenge. However, the treatment and follow-up algorithm change over time. In our study, we aimed to present 10 years of diagnostic and management experience.
