Cholangiocarcinoma is a primary cancer originating in the biliary epithelium i.e., the cholangiocytes, of the extrahepatic and intrahepatic biliary ducts. It is extremely invasive, develops rapidly, often metastasizes, and has a very poor prognosis. They are slow growing tumors which spread longitudinally along the bile ducts with neural, perineural and subepithelial extension. [from HPO]

A parasitic infection that is caused by liver flukes, usually Fasciola hepatica, of sheep, goats, and cattle. Humans become infected by eating uncooked, infested aquatic vegetation (classically watercress). Adult flukes inhabit the bile ducts, gallbladder, and occasionally ectopic sites. Symptoms arise secondary to inflammatory response or obstruction. [from NCI]

A group of parasitoses caused by flat worms that live in contact with epitheliums. Clinical classification depends on the organ infected by the adult parasite: liver, lungs, or intestines. [from ORDO]

Infection with flukes of the genus Opisthorchis. [from MONDO]

An infection that is most commonly caused by the intestinal fluke Metagonimus yokogawai, which is most commonly found in the Far East, and which is transmitted via consumption of contaminated raw or undercooked fish. Symptoms typically range from asymptomatic to intermittent abdominal pain and diarrhea, with occasional ectopic infection. [from NCI]

A parasitic infection characterized by the infestation with worms, mainly in the intestine. [from NCI]

A small bowel infection that is caused by Fasciolopsis buski, which is endemic in the Far East and Southeast Asia, and which is transmitted via the consumption of raw or undercooked aquatic plants. The spectrum of manifestations range from asymptomatic to intestinal symptoms from local invasion or allergic response. [from NCI]

Infection of the biliary passages with clonorchis sinensis, also called Opisthorchis sinensis. It may lead to inflammation of the biliary tract, proliferation of biliary epithelium, progressive portal fibrosis, and sometimes bile duct carcinoma. Extension to the liver may lead to fatty changes and cirrhosis. (From Dorland, 27th ed) [from MONDO]
