Label	Id	Description
Chloracne	D054506	[ACNE-like skin eruptions caused by exposure to CHLORINE-containing compounds. Exposure can be by inhalation, ingestion, or through the skin. Chloracne is often seen in people who have occupational contact with chlorinated pesticides, wood preservatives, and sealants.]
Choanal Atresia	D002754	[A congenital abnormality that is characterized by a blocked CHOANAE, the opening between the nose and the NASOPHARYNX. Blockage can be unilateral or bilateral; bony or membranous.]
Cholangiocarcinoma	D018281	[A carcinoma that originates in the intrahepatic bile duct epithelium of the intrahepatic biliary tree. Malignant lesions are solid, nodular, and grayish. Most cases are adenocarcinomas. Somatic mutations in BAP1, ARID1A, PBRM1, IDH1, and IDH2 genes have been identified. OMIM: 615619, A malignant tumor arising from the epithelium of the BILE DUCTS.]
Cholangitis	D002761	[Inflammation of the biliary ductal system (BILE DUCTS); intrahepatic, extrahepatic, or both.]
Cholangitis, Sclerosing	D015209	[Chronic inflammatory disease of the BILIARY TRACT. It is characterized by fibrosis and hardening of the intrahepatic and extrahepatic biliary ductal systems leading to bile duct strictures, CHOLESTASIS, and eventual BILIARY CIRRHOSIS.]
Cholecystitis	D002764	[Presence of pus in the GALLBLADDER., Inflammation of the GALLBLADDER; generally caused by impairment of BILE flow, GALLSTONES in the BILIARY TRACT, infections, or other diseases.]
Cholecystitis, Acute	D041881	[Acute inflammation of the GALLBLADDER wall. It is characterized by the presence of ABDOMINAL PAIN; FEVER; and LEUKOCYTOSIS. Gallstone obstruction of the CYSTIC DUCT is present in approximately 90% of the cases.]
Cholecystolithiasis	D041761	[Presence or formation of GALLSTONES in the GALLBLADDER.]
Choledochal Cyst	D015529	[A congenital anatomic malformation of a bile duct, including cystic dilatation of the extrahepatic bile duct or the large intrahepatic bile duct. Classification is based on the site and type of dilatation. Type I is most common., Characterized by the fusiform or saccular dilatation of the COMMON BILE DUCT., Characterized by the presence of a singular or multiple intrahepatic cysts., Characterized by the choledochocele dilatation of the distal portion of the COMMON BILE DUCT in the DUODENUM where the pancreatic duct (PANCREATIC DUCTS) enters., Characterized by the diverticulum arising from the extrahepatic biliary tree., Characterized by the presence of multiple extrahepatic and intrahepatic cysts.]
Choledocholithiasis	D042883	[Presence or formation of GALLSTONES in the COMMON BILE DUCT.]
Cholelithiasis	D002769	[Presence or formation of GALLSTONES in the BILIARY TRACT, usually in the gallbladder (CHOLECYSTOLITHIASIS) or the common bile duct (CHOLEDOCHOLITHIASIS).]
Cholera	D002771	[An acute diarrheal disease endemic in India and Southeast Asia whose causative agent is VIBRIO CHOLERAE. This condition can lead to severe dehydration in a matter of hours unless quickly treated.]
Cholera Morbus	D017688	[An old term that is no longer used in the scientific literature. Cholera morbus refers to acute GASTROENTERITIS occurring in summer or autumn; characterized by severe cramps, diarrhea, and vomiting.]
Cholestasis	D002779	[Impairment of bile flow due to obstruction in small bile ducts (INTRAHEPATIC CHOLESTASIS) or obstruction in large bile ducts (EXTRAHEPATIC CHOLESTASIS).]
Cholestasis, Extrahepatic	D001651	[Impairment of bile flow in the large BILE DUCTS by mechanical obstruction or stricture due to benign or malignant processes.]
Cholestasis, Intrahepatic	D002780	[Impairment of bile flow due to injury to the HEPATOCYTES; BILE CANALICULI; or the intrahepatic bile ducts (BILE DUCTS, INTRAHEPATIC).]
Cholesteatoma	D002781	[A non-neoplastic mass of keratin-producing squamous EPITHELIUM, frequently occurring in the MENINGES; bones of the skull, and most commonly in the MIDDLE EAR and MASTOID region. Cholesteatoma can be congenital or acquired. Cholesteatoma is not a tumor nor is it associated with high CHOLESTEROL.]
Cholesteatoma, Middle Ear	D018424	[A mass of KERATIN-producing squamous EPITHELIUM that resembles an inverted (suck-in) bag of skin in the MIDDLE EAR. It arises from the eardrum (TYMPANIC MEMBRANE) and grows into the MIDDLE EAR causing erosion of EAR OSSICLES and MASTOID that contains the INNER EAR.]
Cholesterol Ester Storage Disease	D015217	[An autosomal recessive disorder caused by mutations in the gene for acid lipase (STEROL ESTERASE). It is characterized by the accumulation of neutral lipids, particularly CHOLESTEROL ESTERS in leukocytes, fibroblasts, and hepatocytes.]
Choline Deficiency	D002796	[A condition produced by a deficiency of CHOLINE in animals. Choline is known as a lipotropic agent because it has been shown to promote the transport of excess fat from the liver under certain conditions in laboratory animals. Combined deficiency of choline (included in the B vitamin complex) and all other methyl group donors causes liver cirrhosis in some animals. Unlike compounds normally considered as vitamins, choline does not serve as a cofactor in enzymatic reactions. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984)]
