When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Pseudoxanthoma Elasticum.
Pseudoxanthoma elasticum results from mutations in specific genes, most commonly the ABCC6 gene, which provides instructions for making a protein that transports substances across cell membranes.
Pseudoxanthoma elasticum results from mutations in specific genes, most commonly the ABCC6 gene, which provides instructions for making a protein that transports substances across cell membranes. When this gene doesn't work properly, calcium and other minerals accumulate in elastic fibers throughout the body, making them stiff and fragmented instead of flexible. Think of elastic fibers like tiny rubber bands that help skin stretch and blood vessels expand - when they become calcified, they lose their springiness and can even break.
The condition follows an autosomal recessive inheritance pattern, meaning a person must inherit two copies of the mutated gene (one from each parent) to develop the disorder.
The condition follows an autosomal recessive inheritance pattern, meaning a person must inherit two copies of the mutated gene (one from each parent) to develop the disorder. Parents who carry one copy of the mutation typically don't show symptoms but can pass the gene to their children. In rare cases, mutations in other genes like GGCX or ENPP1 can cause similar symptoms.
The underlying problem isn't just in the skin where symptoms are most visible - the same process affects elastic fibers in blood vessels, the heart, and the eyes.
The underlying problem isn't just in the skin where symptoms are most visible - the same process affects elastic fibers in blood vessels, the heart, and the eyes. This explains why pseudoxanthoma elasticum is considered a systemic condition that requires monitoring of multiple organ systems, not just dermatological care.
Risk Factors
- Having two parents who carry the ABCC6 gene mutation
- Family history of pseudoxanthoma elasticum
- Consanguineous parents (related by blood)
- Certain ethnic backgrounds with higher carrier rates
- Previous child in family diagnosed with the condition
- Being female (slightly higher risk)
- Having relatives with early heart disease or vision problems
Diagnosis
How healthcare professionals diagnose Pseudoxanthoma Elasticum:
- 1
Diagnosing pseudoxanthoma elasticum typically begins when a doctor notices characteristic skin changes during a routine examination or when a patient reports vision problems.
Diagnosing pseudoxanthoma elasticum typically begins when a doctor notices characteristic skin changes during a routine examination or when a patient reports vision problems. The distinctive yellowish bumps and loose skin texture often provide the first clues, especially when they appear in typical locations like the neck, armpits, or groin. Dermatologists can often recognize these signs, but confirming the diagnosis requires additional testing.

The gold standard for diagnosis involves a skin biopsy, where a small sample of affected skin is examined under a microscope using special stains that highlight calcium deposits in elastic fibers.

Genetic testing can identify mutations in the ABCC6 gene and other associated genes, providing definitive confirmation and helping with family planning decisions. Blood tests may show elevated levels of certain minerals or proteins.

A comprehensive evaluation includes eye examinations to look for retinal changes called angioid streaks, cardiovascular assessments to check for early blood vessel disease, and sometimes imaging studies of major arteries.
A comprehensive evaluation includes eye examinations to look for retinal changes called angioid streaks, cardiovascular assessments to check for early blood vessel disease, and sometimes imaging studies of major arteries. The diagnostic process often involves multiple specialists including dermatologists, ophthalmologists, and cardiologists working together to assess the full scope of the condition.
Complications
- Vision complications represent one of the most serious concerns in pseudoxanthoma elasticum, with angioid streaks affecting up to 85% of people with the condition.
- These cracks in the layer beneath the retina can lead to choroidal neovascularization, where abnormal blood vessels grow and leak, potentially causing rapid central vision loss.
- While peripheral vision usually remains intact, reading and detailed tasks may become challenging.
- Cardiovascular complications can include premature hardening of arteries, high blood pressure, and increased risk of heart attack or stroke at younger ages than typical.
- Gastrointestinal bleeding may occur due to weakened blood vessels, and some people experience reduced blood flow to legs, causing pain with walking.
- While these complications sound serious, many can be effectively managed with proper medical care, and most people with pseudoxanthoma elasticum maintain good quality of life with appropriate monitoring and treatment.
Prevention
- Since pseudoxanthoma elasticum is an inherited genetic condition, primary prevention isn't possible.
- However, genetic counseling can help families understand inheritance patterns and make informed decisions about family planning.
- Couples with a family history of the condition can pursue genetic testing to determine their carrier status and discuss options like preimplantation genetic diagnosis.
- Secondary prevention focuses on slowing disease progression and preventing complications.
- This includes protecting skin from sun damage with broad-spectrum sunscreen and avoiding trauma that might worsen skin changes.
- A heart-healthy lifestyle with regular exercise, balanced nutrition, and avoiding smoking can help protect cardiovascular health.
- Regular monitoring allows for early detection and treatment of complications before they become serious.
- Eye exams every 6-12 months can catch retinal changes early, while cardiovascular screenings help identify blood vessel problems.
- Some people benefit from avoiding contact sports or activities that might cause eye injury, and maintaining good blood pressure control is essential for long-term health.
Currently, there's no cure for pseudoxanthoma elasticum, but treatment focuses on managing symptoms and preventing complications through careful monitoring and targeted interventions.
Currently, there's no cure for pseudoxanthoma elasticum, but treatment focuses on managing symptoms and preventing complications through careful monitoring and targeted interventions. Skin changes typically don't require specific treatment beyond sun protection and gentle skincare, though some people choose cosmetic procedures to address loose or aged-appearing skin.
Eye complications require close monitoring by retinal specialists, as vision changes can develop gradually.
Eye complications require close monitoring by retinal specialists, as vision changes can develop gradually. Anti-VEGF injections may help slow progression of choroidal neovascularization, a serious complication that can cause rapid vision loss. Low-vision aids and rehabilitation services can help people adapt to vision changes when they occur.
Cardiovascular management is crucial and may include medications to control blood pressure, cholesterol-lowering drugs, and antiplatelet therapy to reduce clotting risk.

Some people benefit from procedures to open narrowed arteries. Regular exercise within individual limitations, heart-healthy diet modifications, and smoking cessation are essential lifestyle components.
Researchers are investigating promising treatments including bisphosphonates to reduce calcium deposits, antioxidants to protect tissues, and gene therapy approaches.

Clinical trials are exploring whether certain supplements or medications might slow the progression of elastic fiber calcification, offering hope for more targeted treatments in the future.
Living With Pseudoxanthoma Elasticum
Living successfully with pseudoxanthoma elasticum involves building a strong healthcare team and staying proactive about monitoring. Regular appointments with dermatologists, ophthalmologists, and cardiologists help catch changes early. Many people find it helpful to keep a health journal tracking any new symptoms and maintaining records of all test results and specialist visits.
