Skin Diseases & Autoimmune Conditions That Can Cause Open Wounds
Not all wounds are caused by poor circulation, diabetes, or trauma. Certain skin diseases and autoimmune conditions can also damage the skin and lead to painful ulcers or chronic non-healing wounds. These wounds often look very different from typical pressure injuries or venous ulcers, and they require a very different treatment approach.
At the Vein & Wound Center of LA, Dr. Christopher Kim’s background in surgical training and limb salvage—along with years of experience managing thousands of complex wounds—means that we carefully evaluate each wound’s underlying cause before deciding on treatment.
Autoimmune & Dermatologic Conditions That May Present With Open Wounds
Some conditions that can mimic or complicate chronic wounds include:
- Pyoderma Gangrenosum
A rare autoimmune condition that causes rapidly enlarging painful ulcers, often on the legs. These are frequently misdiagnosed as infections or venous ulcers, but antibiotics alone won’t help. - Vasculitis
Inflammation of small or medium blood vessels can cause painful ulcers, particularly around the ankles or lower legs. - Lupus (Systemic or Cutaneous)
Autoimmune lupus can cause skin rashes, breakdown, and ulcerations, especially in sun-exposed areas or areas with poor circulation. - Bullous Diseases (e.g., Pemphigoid, Pemphigus)
Autoimmune blistering disorders may rupture and leave open erosions that look like non-healing wounds. - Other inflammatory dermatoses (e.g., lichen planus, necrobiosis lipoidica, severe eczema or psoriasis)
In some cases, chronic inflammation and skin breakdown can lead to ulcer formation.
Why Accurate Diagnosis Matters
The treatment for autoimmune or dermatologic ulcers is very different from standard wound care. For example:
- A venous ulcer responds to compression and vein treatment, but an autoimmune ulcer may worsen with those measures if misdiagnosed.
- Topical or systemic steroids, immunosuppressive medications, or biologic therapies may be required for autoimmune causes.
- Infection is often not the primary driver, so antibiotics alone will not lead to healing.
Because of this, accurate diagnosis is critical to avoid delays in healing and unnecessary procedures.
Role of Skin Biopsy
In many cases, a skin biopsy is the most effective way to identify the underlying condition.
- A small sample of tissue is taken from the edge of the wound under local anesthesia.
- The sample is sent to pathology for microscopic and immunologic analysis.
- Results can confirm diagnoses like vasculitis, pyoderma gangrenosum, or autoimmune blistering disorders.
This step is often key to guiding specialist referral (e.g., dermatology, rheumatology) and initiating the right therapy.
Our Multidisciplinary Approach
At the Vein & Wound Center of LA, we don’t just treat the wound surface—we work to uncover the root cause. Our process includes:
- Comprehensive evaluation of the wound and patient history.
- Diagnostic testing including blood work, vascular studies, and skin biopsy when indicated.
- Collaboration with dermatology and rheumatology specialists if autoimmune or inflammatory disease is suspected.
- Tailored wound management using advanced dressings, topical therapies, or systemic treatments based on the underlying diagnosis.

- Patient-centered care: Each case is approached individually with an emphasis on accuracy, safety, and long-term healing.
Frequently Asked Questions
Q: How do I know if my wound is autoimmune and not vascular or diabetic?
A: Autoimmune ulcers often appear suddenly, are very painful, or do not respond to standard treatments like compression or antibiotics. A proper evaluation—including biopsy—is the best way to know.
Q: What is a skin biopsy, and is it painful?
A: A skin biopsy involves taking a small tissue sample from the wound edge under local anesthesia. The procedure is quick and usually well-tolerated, with minimal discomfort.
Q: Who treats autoimmune ulcers?
A: Wound care specialists often work with dermatologists and rheumatologists. At our clinic, we coordinate care across specialties so you receive the right diagnosis and treatment.
Q: Can autoimmune ulcers be cured?
A: Many autoimmune conditions can be managed effectively with medication, advanced dressings, and specialist care. Early diagnosis greatly improves outcomes.
Q: Why is experience important in managing these wounds?
A: Because autoimmune and dermatologic ulcers can mimic more common wounds, misdiagnosis is common. An experienced wound care physician with surgical training—like Dr. Kim—can recognize when a wound doesn’t fit the usual pattern and order the right tests.
