Background: Appendectomy for acute appendicitis is one of the most common procedure performed by general surgeons. While appendicitis is the primary indication for this surgery, there exists a subset of cases where unexpected neoplastic pathologies are incidentally discovered during pathological examinations of removed appendix. Aim: This study aimed to investigate the incidence, type of neoplastic pathologies incidentally discovered during the pathological examination of excised appendices in cases where preoperatively malignancy was not suspected. Materials and methods: A retrospective analysis was conducted on a cohort of appendectomy patients over a period of 2 yrs from 9 January 2022 to 9 January 2024.The medical records of patients who underwent appendectomy was reviewed to identify cases of appendiceal neoplasms. The overall incidence of neoplasms along with demographical characteristics and clinical outcomes of affected patients were retrieved from records. Results: 1021 patients diagnosed with acute appendicitis underwent open appendectomy. 12 neoplasms were found with an incidence of 1.17%,the appendiceal tumours increased in age group of 50-70 yrs .The most frequent appendiceal neoplasms was appendiceal neuroendocrine neoplasms 6 cases ( 0.58%) followed by appendiceal adenocarcinoma 4 cases (0.39%), non Hodgkin lymphoma 2 cases (0.19%). Conclusion: Appendiceal tumours are rare and must be ruled out in acute appendicitis in elderly patients. This data should be utilised to understand occult neoplasms in context of open appendectomy prompting continued exploration of diagnostic and clinical considerations in management of appendiceal malignancies.
