A 72 year-old woman was admitted to our hospital because of back pain due to compression fracture of the 8th thoracic spine. On the 34th hospital day she complained epigastric pain. Ultrasonogram revealed hypoechoic elevated lesions of gallbladder. ERCP and endoscopic ultrasonogram also demontrated protruded lesion of the Gallbladder. These findings suggested advanced gallbladder cancer, and extended cholecystectomy was performed. Macroscopic finding of the resected gallbladder showed green elevated lesions with normal surrounding mucosa. Gallbladder stone was not present. Microscopic study disclosed the elevated lesions consisting of garnulation tissue and necrosis. Few cases of acute acalculous cholecystitis with mucosal elevation have been reported and attention should be payed for differential diagnosis from advanced gallbladder cancer.
