A case of early gallbladder cancer associated with cholesterosis

Abstract

We experienced a case of gallbladder cancer with cholesterosis.
A 71-year-old woman underwent a medical checkup and a protruded lesion of the gallbladder was detected by an abdominal US.
Abdominal US revealed a echogenic lesion, measuring 20mm, with irregular surface at the fundus of the gallbladder.
The protruded lesion was enhanced by administration of contrast medium on abdominal CT.
Under diagnosis of the carcinoma of the gallbladder, she underwent an open cholecystectomy.
The resected specimen showed a 20mm elevated lesion at the fundus of the gallbladder.
Histologically, this was demonstrated to be well differentiated adenocarcinoma associated with cholesterosis, stage I.
