Small cell carcinoma of the liver and biliary tract without jaundice

摘要

An 80-year-old woman presenting with chest pain was found to have a large,lobulated soft tissue mass in the liver and nearby tissues on abdominal computed tomography(CT).The tumor had invaded the common hepatic artery and main portal vein.Jaundice developed 4 wk later,at which point,a pancreas and biliary CT scan revealed a large mass in the right lobe of the liver and a hilar duct obstruction,which was found to be a small cell carcinoma.Despite its rarity,liver and bile duct small cell carcinoma should be considered in the differential diagnosis of atypical chest pain without jaundice.
