Moderately differentiated adenocarcinoma of gallbladder in a 59 year old man. A. Tumor bounds cystic duct. B. Cystic duct at left shows high grade dysplasia. At right lie acini and nests of round and sometimes spindled cancerous nuclei. Overall most of the tumor was in tubules/acini, meaning the lesion is moderately differentiated. C. Region with Rokitansky-Aschoff sinuses showing high grade dysplasia and foci of intestinal metaplasia, with some nests likely being invasive cancer. D. Tumorous involvement of cystic duct lymph node. E. Bizarrely shaped cancerous groups. F. invasion of liver by neoplastic acini. | |||
