 [ko-lan″je-o-kahr″sĭ-no´mah]
1. an adenocarcinoma arising from the epithelium of the intrahepatic bile ducts, composed of eosinophilic cuboidal or columnar epithelial cells, with abundant fibrous stroma; mucus may be secreted but not bile.

chol·an·gi·o·car·ci·no·ma

(kō-lan'jē-ō-kar'si-nō'mă),
An adenocarcinoma, primarily in intrahepatic bile ducts, composed of ducts lined by cuboidal or columnar cells that do not contain bile, with abundant fibrous stroma; cirrhosis is usually absent.

cholangiocarcinoma

[kōlan′jē·ōkär′sinō′mə]
a cancer of the biliary epithelium. Risk factors include ulcerative colitis and infestation of liver flukes. Diagnosis is based on histological evaluation, and the prognosis is poor.

cholangiocarcinoma

Location
Hilar, 50–60%; intrahepatic, 10%; extrahepatic 20–30%.

Prognosis
