Klatskin tumor

Prevalence ?
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant ?A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease

no.svg

Autosomal recessive ?Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype

no.svg

X-linked dominant ?X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

no.svg

X-linked recessive ?Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder

no.svg

Mitochondrial or multigenic ?Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

no.svg

Multigenic or multifactor ?Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary

Klatskin tumors are are a type of cholangiocarcinoma that begins in an area called the hilum, where the left and right bile ducts join and leave the liver. It is the most common type of cholangiocarcinoma, accounting for more than half of all cases.[1][2][3][4] Symptoms usually don't present until advanced stages of disease, when jaundice is the most common feature. Other symptoms include abdominal pain, unintentional weight loss, and a general feeling of being unwell (malaise).[3][4] 

The cause of Klatskin tumors is unknown.[2] Studies suggest that a combination of genetic, environmental, and lifestyle factors (multifactorial) likely influence whether a person will develop cholangiocarcinoma. Because Klatskin tumors are often discovered after they have spread, they can be challenging to treat.[3] Surgical removal of the tumor and relief of bile duct blockage are the main goals of treatment.[1][2][4]

Symptoms

The symptoms associated with Klatskin tumors are usually due to blocked bile ducts. Symptoms may include:[1][2][3]

  • Jaundice
  • Itching
  • Light colored stools and/or dark urine
  • Abdominal pain
  • Loss of appetite / weight loss
  • Fever
  • Nausea / vomiting

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.
