When we hear the word rash, we often think of a cosmetic issue that we can resolve with a topical cream. However, sometimes a rash can be a physical sign of a more serious underlying condition.

In the case of some rheumatic diseases, a rash may be one of the earliest warning signs. Therefore, it’s essential to know when a rash could be more than skin deep.

What Are Rheumatic Diseases?

Rheumatic diseases are a collection of autoimmune disorders that affect the joints, muscles, and bones. When someone has a rheumatic disease, their immune system mistakenly attacks healthy tissues within the body, causing inflammation and damage.

There are over 100 types of rheumatic diseases, and many of them can cause a rash or skin condition.

Types of Rheumatic Diseases That Can Cause a Rash

Although not every rheumatic disease presents with a rash, some of the most common ones that do include:.

Lupus – A chronic condition where the immune system attacks various organs and tissues throughout the body.
Dermatomyositis – A rare inflammatory disease that causes muscle weakness, as well as a distinctive skin rash.
Juvenile Rheumatoid Arthritis – A type of arthritis that affects children and young adults and can trigger skin rashes.
Rheumatoid Arthritis – A chronic inflammatory disorder that mainly affects the joints but can also cause skin problems such as rashes and nodules (bumps).

Types of Rashes Associated with Rheumatic Diseases

While many types of rashes can develop as a result of rheumatic diseases, some of the most common ones include:.

Butterfly Rash – A rash that appears across the nose and cheeks, often seen in those with lupus.
Gottron’s Papules – Raised bumps that appear on the knuckles, a common symptom of dermatomyositis.
Rheumatoid Nodules – Firm lumps that form under the skin, usually around joints, of people with rheumatoid arthritis.
Palmar Erythema – When the palms become reddish, which is common in patients with different rheumatic disorders.
Photosensitivity – Increased sensitivity to sunlight, which is a common symptom of lupus, dermatomyositis, and some forms of vasculitis.

Why Does a Rash Develop with Rheumatic Diseases?

A rash may occur in individuals with rheumatic diseases because of the inflammation caused by their immune system. The inflammation that occurs with rheumatic diseases can cause damage to the joints, muscles, and bones, but it can also affect the skin.

Immune complexes form under the skin and other organs, which lead to the development of a rash.

When Should You Seek Medical Attention?

If you are experiencing a rash, especially if you have a rheumatic disease or a history of one, it’s crucial to seek medical attention. A rash may signal early stage symptomatology of an autoimmune disorder.

A rheumatologist may order some tests to determine if the rash is related to your autoimmune disease, such as a biopsy that samples the affected skin. If the rash is associated with a rheumatic disease, your doctor may recommend starting treatment. Early intervention can be essential because it can help to avoid complications and control symptoms.

Conclusion

Although a rash may seem like a minor issue, it can be a sign of a more severe underlying condition, especially for individuals who have a history or presence of autoimmune disorders.

Getting an accurate diagnosis and course of treatment is crucial when it comes to rheumatic diseases. If you notice a rash or skin condition that’s not resolving, make sure to seek medical attention from your physician promptly.
