What is XP in medical terms?
on March 31, 2020. Xeroderma pigmentosum (XP) is an inherited disease that causes extreme sensitivity to ultraviolet (UV) light.

Over-The-Counter Therapies
- In addition to buying preventive items at the drugstore, such as sunscreen and sunglasses or analgesics to deal with the pain of a sunburn, you can also pick up vitamin D, which is needed to build healthy bones. Normally, the body creates vitamin D when exposed to the sun. Since thos…
Prescriptions
- For some severely affected patients, the prescription medication isotretinoin, an oral medication derived from vitamin A, may reduce the number of skin tumors that arise.4 The downside is this medication is associated with severe side effects such as causing high levels of cholesterol and triglycerides in the blood, the potential to cause defects in developing fetuses, and painful calciu…
Surgeries and Specialist-Driven Procedures
- For those with XP, surgeries to remove precancerous and cancerous lesions are a large part of surgical treatment. This means that ongoing screening is also an important part of the treatment process. Those with XP should follow this screening routine: 1. Every three to six months have your skin carefully checked by a professional who is trained to spot skin cancer. 2. As often as p…
Summary
- For those with XP, treatment for skin lesions and any eye-related or neurological symptoms remains limited. Preventive measures such as wearing protective clothing and sunscreen and avoiding UV exposure are the mainstays. Also, early removal of any precancerous or cancerous lesions that arise is key here and relies on frequent screening measures.
A Word from Verywell
- While, currently, treatment options for XP are limited to prevent skin lesions or eye symptoms, the hope for the future is that a genetic treatment will be developed that will enable those with XP to enjoy the light without any consequences.
Overview
Genetics
Symptoms
- People with xeroderma pigmentosum experience skin symptoms and changes from being in the sun. These may include: The name xeroderma pigmentosum means dry pigmented skin. Exposure to the sun over time causes the skin to become darker, dry, and parchment-like. Even in children, the skin looks like the skin of farmers and sailors who have been in the sun for many years. Peo…
Epidemiology
- People with xeroderma pigmentosum who are younger than 20 years old have more than 1,000 times the risk of developing skin cancer than people without the disease. The first skin cancer may develop before a child with XP is 10 years old, and many more skin cancers may develop in the future. In XP, skin cancer develops most often on the face, the lips, on the eyes, and on the ti…
Diagnosis
- The diagnosis of xeroderma pigmentosum is based on the skin, eye, and nervous system symptoms (if present). A special test performed on blood or a skin sample can look for the DNA repair defect present in XP. Tests may be done to rule out other disorders that can cause similar symptoms, such as Cockayne syndrome, trichothiodystrophy, Rothmund-Thomson syndrome, o…
Treatment
- There is no cure for xeroderma pigmentosum, so treatment focuses on any problems that are present and preventing future problems from developing. Any cancers or suspicious lesions should be treated or removed by a skin specialist (dermatologist). An eye specialist (ophthalmologist) can treat any eye problems that occur.
Prevention
- Since it is the UV light that causes damage, a big part of prevention of problems is protecting the skin and eyes from sunlight. If someone with XP has to go outside during the day, he or she should wear long sleeves, long pants, gloves, a hat, sunglasses with side shields, and sunscreen. When indoors or in a car, the windows should be closed to block the UV rays from sunlight (alth…
Others
- Some types of indoor light (such as halogen lamps) can also give off UV light. Indoor sources of UV light in the home, school, or work environment should be identified and eliminated, if possible. People with XP can also wear sunscreen indoors to protect against unrecognized sources of UV light.
