title: Acute appendicitis secondary to metastatic bronchogenic adenocarcinoma.
abstract: Metastatic tumors to the appendix are not common. However, these tumors should be one of the differential diagnoses in patients with known primary malignancy, who present with signs and symptoms of acute appendicitis. We report a case of an elderly male with poorly differentiated bronchogenic adenocarcinoma which metastasized to the appendix.
