Gallbladder carcinoma (GBC) is a lethal and rare disease despite it being the most common malignancy of the biliary tract. Most cases of GBC are also associated with cholelithiasis and inflammation. The poor prognosis of GBC is mainly due to a lack of symptoms in the early stages of the disease. Early detection and cholecystectomy can lead to a higher survival rate when the cancer is confined to the gallbladder mucosa. This case study describes a man in his late 50s who presented with elevated liver function tests and was diagnosed incidentally with GBC with sonography.
