Abstract
A 58-year-old male was admitted to our hospital for workup of gallbladder tumor pointed out by complete physical examination. Ultrasonography and CT-scan showed an elevated lesion with irregular margin about 3 cm in diameter. In enhanced CT, the same elevated lesion was visualized as high density area. Abdominal angiography demonstrated tumor stein without encasement in the gallbladder. A diagnosis of carcinoma of the gallbladder was made, and extended cholecystectomy was performed. Histopathology revealed that the main elevated lesion ( I ) was well differentiated adenocarcinoma. However, two small polypoid lesions ( IIa) and broad flat cancerous lesions ( IIb) were pointed out around the main lesion.
