Appendicular neoplasms are rare tumors, with an incidence of less than 0.05% among all gastrointestinal tumors. This work presents the case of a 52-year-old patient who manifested colicky pain in the right iliac fossa. Laboratory test results with bandemia and hyperbilirubinemia. Abdominal tomography with an acute appendicular inflammatory process, for which the patient was admitted for surgery. A dependent tumor of the cecum and appendicular region is observed, which compromises the ileocecal valve. The histopathological diagnosis was “low-grade appendiceal mucinous neoplasm.” Appendiceal tumors are often incidental findings due to their low frequency; however, their possibility should not be dismissed.
