Understanding the Differences Between Rosacea and Lupus

Understanding the Differences Between Rosacea and Lupus

Rosacea and lupus are two chronic inflammatory conditions that affect the skin and have some overlapping symptoms like facial redness and flushing. However, they are distinct diseases with different causes and treatments. Understanding the key differences between rosacea and lupus can help ensure proper diagnosis and management.

What is Rosacea?

Rosacea is a common chronic skin condition estimated to affect over 16 million Americans. It typically begins anytime after age 30 as a redness or flushing on the cheeks, nose, chin or forehead that may come and go. Over time, rosacea tends to worsen and spread to involve more of the facial skin.

In addition to facial redness, rosacea signs and symptoms may include:

• Flushing or blushing more easily
• Visible blood vessels on the face
• Bumps or pimples on facial skin
• Watery or irritated eyes
• Thicker facial skin

There are four main subtypes of rosacea:

• Erythematotelangiectatic rosacea - characterized by persistent redness and flushing
• Papulopustular rosacea - involves acne-like breakouts
• Phymatous rosacea - leads to thickening skin and enlargement of nose
• Ocular rosacea - causes dry, irritated, watery eyes

The exact cause of rosacea is unknown, but it appears related to a combination of genetic and environmental factors. Potential rosacea triggers include sun exposure, hot or cold weather, wind, heavy exercise, spicy foods, alcohol, hot baths, emotional stress and more.

What is Lupus?

Lupus is an autoimmune disease where the immune system attacks healthy cells and tissues, leading to widespread inflammation and other signs throughout the body. The most common type is systemic lupus erythematosus (SLE).

In SLE, the immune system produces antibodies that target tissues in organs like the heart, joints, kidneys, brain, skin and more. This causes symptoms that may include:

• Fatigue and fever
• Joint pain or swelling
• Chest pain
• Headaches
• Photosensitivity
• Hair loss
• Oral ulcers
• Skin rashes

SLE can range from mild to life-threatening. The exact underlying cause is not known, but risk factors include genetics, environment, hormones and immune system dysfunction.

Facial Redness Differences

Both rosacea and lupus can cause degrees of facial redness or flushing. However, there are some differences:

• In rosacea, facial redness is typically confined to the center of the face and does not spread to other areas of the body.
• Lupus rashes are not limited to the face and can appear elsewhere on the body.
• Rosacea reddening is often triggered by factors like sun, stress or spicy foods.
• Lupus rashes may be sensitive to sunlight but are not triggered by other rosacea factors.
• Rosacea redness comes and goes but tends to be chronic once established.
• Lupus rashes may wax and wane depending on disease activity.

The 'Lupus Butterfly Rash'

One telltale sign of lupus is the "butterfly rash". This facial rash extends over both cheeks and across the bridge of the nose, resembling the shape of a butterfly:

• Appears on sun-exposed areas like the face and arms
• Consists of flat, red patches with well-defined edges
• Does not typically cause permanent skin changes
• May be transient, lasting for days or weeks

This distinctive rash appears in about half of people with SLE. Rosacea does not manifest with the butterfly rash.

Acne-like Bumps

Both rosacea and lupus can involve acne-like bumps or pimples on the skin. However, there are some differences:

• In rosacea, small dome-shaped red pimples and pustules develop on facial skin. They may be filled with pus.
• Lupus can cause acne-like lesions too, but these can appear anywhere on the body.
• Rosacea bumps tend to persist on the face. Lupus bumps may come and go.
• Rosacea papules are superficial. Lupus sores can sometimes ulcerate or scar.

Eye Symptoms

Rosacea and lupus can both cause eye problems:

• Ocular rosacea leads to irritated, watery, dry, swollen eyes with a gritty feeling.
• Lupus can cause sores on the eyelids and light sensitivity.
• Inflammation inside the eye is more common in lupus.
• Vision loss is very rare in rosacea but can occur in lupus.

Causes of Each Condition

The underlying disease mechanisms behind rosacea and lupus are different:

• Rosacea involves abnormal inflammatory reactions in facial skin blood vessels. Immune system dysfunction may play a secondary role.
• Lupus is an autoimmune disorder driven by the immune system mistakenly attacking the body's own cells and tissues.

Who Gets Affected?

Rosacea and lupus have different demographic patterns:

• Rosacea typically begins after age 30 and peaks between ages 50-60. It mainly affects fair-skinned people of European descent.
• Lupus often starts between ages 15-44 and primarily affects women. It is more common in people of African, Asian and Native American descent.

Co-Occurrence of Rosacea and Lupus

It is possible for a person to have both rosacea and lupus simultaneously. Features that may suggest both conditions include:

• Facial redness spreading to other areas of the body
• Acne-like breakouts on both the face and body
• Very sensitive or inflammatory eye symptoms
• Flushing and redness triggered by other lupus symptoms

However, most patients will only have one or the other condition. Checking for wider symptoms can help distinguish whether rosacea, lupus or both diseases are present.

Diagnosis of Rosacea vs Lupus

Proper diagnosis involves:

• Evaluating the full pattern of signs and symptoms
• Looking for specific indicative features of each disease
• Considering risk factors and demographics
• Examining potential disease co-occurrence
• Running blood tests to look for autoimmune markers present in lupus
• Possibly doing a biopsy to examine skin tissue

This thorough workup helps distinguish rosacea from lupus or a combination of the two conditions.
