Colangiocarcinoma: Actualización, diagnóstico y terapia

Cholangiocarcinoma is a malignant lesion of the bile duct epithelium. Its incidence and prevalence are low. It appears from the sixth decade of life and there is slight male predominance. It is most frequently found in the confluence of the hepatic ducts, where it is called hilar cholangiocarcinoma...
