Primary cystadenomatous tumors of the bile ducts

Abstract

Two cases of cystadenomatous tumors of the biliary tract are presented. One was a cystadenoma and the other one was a cystadenocarcinoma. They are rare tumors, difficult to diagnose accurately preoperatively. The differential diagnosis of the cystic tumors of the liver in countries with a high incidence of liver hydatid disease is very important.
