Pseudoxanthoma Elasticum

Pseudoxanthoma elasticum is a rare genetic condition that affects connective tissue throughout the body, particularly elastic fibers that help give tissues their flexibility and strength. While the name might sound intimidating, it simply describes how the skin changes appear under a microscope - resembling yellow deposits but actually involving calcium buildup in elastic fibers.

Symptoms

Common signs and symptoms of Pseudoxanthoma Elasticum include:

Small yellowish bumps on the neck, armpits, or groin
Loose, sagging skin that feels like plucked chicken skin
Gradual vision changes or blind spots
Easy bruising and bleeding
High blood pressure at a young age
Leg pain when walking (claudication)
Yellowish streaks in the back of the eye
Skin that appears aged beyond years
Difficulty seeing in dim light
Nosebleeds or gastrointestinal bleeding
Fatigue with physical activity
Changes in skin texture and elasticity

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.

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.
