Notwithstanding, the risk of missing an appendiceal tumor must be considered, being the surgical piece crucial to rule out neoplasms. Therefore, we aim to determine the incidence of appendiceal neoplasms in patients with acute appendicitis, tumor types and the importance of the anatomopathological study of the surgical piece.  \nStudy design Retrospective study in which we described patients who underwent emergent appendectomy with histopathological findings of appendiceal neoplasms from January 2012 to September 2018. Descriptive analysis included demographic variables, diagnostic methods, and surgical techniques.  \nResults 2993 patients diagnosed with acute appendicitis who underwent an emergency appendectomy. 64 neoplasms of the appendix were found with an incidence of 2,14%. 67.2% were women, the mean age was 46,4 years (± 19 . 5) . The most frequent appendiceal neoplasms were neuroendocrine tumors (42,2%), followed by appendicealmucinous neoplasms (35,9%), sessile serrated adenomas (18,8%), and adenocarcinomas (3,1%) . In 89,1% of the cases, acute appendicitis was determined by imaging, and 14% of cases were suspected intraoperatively. Appendectomy was performed in 78,1% without additional procedures.  \nConclusions Appendiceal tumors are rare and must be ruled out in patients with suspected acute appendicitis. The incidence of incidental neoplasms is higher in this study than in the previously reported series. This information must be included in decision-making when considering treatment options for acute appendicitis.  \nKeywords Appendiceal neoplasms, Appendectomy, Appendicitis, Neuroendocrine tumor, Appendiceal mucinous neoplasms, Sessile serrated adenomas  \n*Correspondence:  \nFelipe Girón  \n[felipegiron15@gmail.com](felipegiron15@gmail.com)  \n1Hospital Universitario Fundación Santa Fe de Bogotá, Calle 119 No. 7-14, Bogotá, DC, Colombia  \n2School of Medicine, Universidad de los Andes, Cundinamarca, Colombia 3Hospital Universitario San Ignacio, Bogotá, Colombia  \n© The Author(s) 2023.
