Mycoplasma Skin Rash is associated with respiratory problems, particularly the infamous Mycoplasma pneumoniae, which results in “walking pneumonia.” Few, however, know that this small bacterium is also capable of causing skin rashes.
Here, we will talk about what a Mycoplasma skin rash is, why it occurs, how to identify it, and its treatment.
What Is Mycoplasma pneumoniae?
Mycoplasma Skin Rash is associated with respiratory problems, particularly the infamous Mycoplasma pneumoniae, which results in “walking pneumonia.” Few, however, know that this small bacterium is also capable of causing skin rashes.
Here, we will talk about what a Mycoplasma skin rash is, why it occurs, how to identify it, and its treatment.
Why Does Mycoplasma Cause Skin Rashes?
The Mycoplasma skin rash isn’t caused by the bacteria directly infecting the skin. Rather, it’s usually a consequence of:
- Immune response to the infection
- Hypersensitivity reactions
- Secondary infections, like Stevens-Johnson Syndrome (SJS)
These rashes are extrapulmonary manifestations—symptoms that manifest outside the lungs.
What Does the Rash Look Like?
A Mycoplasma skin rash may be varied, but these are the most common presentations:
1. Maculopapular Rash
- Flat, red spots with tiny bumps (papules)
- Typically on trunk, arms, or legs
- May be itchy or mildly uncomfortable
2. Urticaria (Hives)
- Itchy, raised, red welts
- Can develop and resolve suddenly
- It may be caused by fever or medications
3. Erythema Multiforme
- Red target-like lesions with a dark center
- Usually occurs on hands, feet, or face
- May be painful
4. Stevens-Johnson Syndrome (Serious but Rare)
- Severe skin eruption with blistering and peeling of the skin
- Often affects the mouth, eyes, and genitalia
- Medical emergency
Important: Mild rashes may resolve on their own, but severe reactions such as Stevens-Johnson Syndrome need to be hospitalized immediately.
Who’s at Risk?
- Children and adolescents are at higher risk of developing Mycoplasma-related rashes
- Those with compromised immune systems will have worse symptoms
- Some genetic susceptibilities can predispose individuals for immune-mediated reactions such as SJS
Diagnosis
Diagnosing a Mycoplasma-related skin rash usually entails:
- Clinical history: Recent respiratory infection or exposure to an individual with walking pneumonia
- Physical examination: To evaluate rash pattern and severity
- Blood work or PCR: To identify Mycoplasma infection
- Skin biopsy: In unusual or ambiguous cases
Treatment
Treatment based on the severity of the rash and underlying infection:
For Mild Rashes:
- Antibiotics like azithromycin or doxycycline to cure the infection
- Antihistamines for itching
- Topical steroids for inflammation reduction
For Severe Reactions (e.g., SJS):
- Hospitalization
- IV fluids and wound management
- Discontinuation of suspected offending medications
- Supportive care in a burn unit, in some cases

When to Seek Medical Care
Consult a doctor if you or your child has:
- A fever with an extensive rash
- Painful sores or peeling on the skin
- Mucous membrane involvement (mouth, eyes, genitals)
- Shortness of breath or features of severe allergy
Mycoplasma Skin Rash – FAQs
A Mycoplasma skin rash is a skin reaction that sometimes occurs during or after infection with Mycoplasma pneumoniae, a type of bacteria that commonly causes respiratory infections (especially atypical pneumonia).
The rash itself is not contagious, but the underlying Mycoplasma infection is. It spreads through respiratory droplets (coughing, sneezing).
Mild rashes may resolve in a few days to a week
More severe forms (like SJS) can last weeks and require intensive care
Yes, if you’re infected with Mycoplasma again or have a similar immune reaction. Also, if you’ve had Stevens-Johnson Syndrome, certain medications or infections can trigger recurrence — discuss this with your doctor.
Final Thoughts
Although Mycoplasma skin infections are often mild and go away with treatment, occasionally they are a sign of a more severe complication. Having an idea of what to do—recognizing what to look for—and when to get assistance can be the difference-maker.
If you think a rash is due to a recent respiratory infection, particularly in a teen or child, don’t wait to contact a healthcare provider.
