Methodology: This was an observational, cross-sectional, and retrospective study. Results: A total of 7 cases (0.81%) of appendiceal tumors were obtained from 860 appendectomies (6 cases of adenoma, and 1 case of moderately differentiated grade 2 infiltrating adenocarcinoma of the cecal appendix). This is the case of a 76-year-old woman. Conclusions: The most common anatomopathological diagnosis of tumor etiology in this population was adenoma followed by adenocarcinoma.
