Incidentally Detected Gallbladder Adenocarcinoma Presenting as Acute Calculous Cholecystitis: A Case Report and Management Considerations.

Gallbladder cancer is an aggressive malignancy of the biliary tract with a poor prognosis and variable geographic distribution. It may be identified incidentally after a cholecystectomy performed for presumed benign disease, with diagnosis established on final histopathological examination. Surgeons should be aware of this possibility, as incidental detection has important implications for staging and subsequent management. Early recognition and appropriate evaluation are essential to guide treatment and improve outcomes.
