Palmoplantar keratoderma

Summary Summary

Tylosis with esophageal cancer (TOC) is an inherited condition characterized by palmoplantar keratoderma and esophageal cancer. The palmoplantar keratoderma usually begins around age 10, and esophageal cancer may form after age 20. This condition is caused by a mutation in the RHBDF2 gene and is inherited in an autosomal dominant pattern.^[1]^[2]^[3]

Symptoms Symptoms

The main features of Tylosis with esophageal cancer are palmoplantar keratoderma and esophageal cancer. The palmoplantar keratoderma usually begins around age 10, and the soles of the feet are usually more severely affected that the palms of the hands. Esophageal carcinoma usually develops in the lower two-thirds of the esophagus at an average age of 45 years.^[4]

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.

Cause Cause

Mutations in the RHBDF2 gene have been shown to cause the development of this condition. ^[5]^[2]^[3]

Last updated: 1/18/2013

Inheritance Inheritance

This condition has an autosomal dominant pattern of inheritance, which means that a mutation in one copy of the altered gene in each cell is sufficient to cause the disorder.^[1] Affected individuals typically have one parent with the condition.

Last updated: 1/18/2013

Treatment Treatment

Affected individuals may have periodic endoscopic and oral cavity evaluations by a gastroentrologist to detect esophageal cancer.^[1] For the palmoplantar keratoderma, a dermatologist may recommend oral retinoids such as etretinate, isotretinoin, and acitretin.^[4] Topical therapies may include soaking in salt water and then gentle removal of dead tissue (debridement) and 50% propylene glycol in water under plastic dressing overnight weekly.^[4]
