Panniculitis
What is Panniculitis?
Panniculitis is a rare condition that causes inflammation in the fatty layer underneath your skin. This layer, called subcutaneous fat, sits between your skin and your muscles. When it becomes inflamed, you may notice painful lumps or nodules under your skin.
The condition can affect anyone but is more common in women between ages 30 and 60. Panniculitis can occur on its own or as a result of another medical condition. There are many different types, each with different causes and characteristics.
Most cases involve tender, red bumps that appear on the legs or other areas of the body. These nodules can range from small to several inches wide. Understanding the underlying cause is important for effective treatment and preventing future flare-ups.
Symptoms
- Painful, tender lumps or nodules under the skin
- Red or purple discoloration over affected areas
- Swelling in the fatty tissue beneath the skin
- Firm or hard bumps that may feel warm to the touch
- Fever and fatigue during active inflammation
- Weight loss or general feeling of being unwell
- Joint pain or muscle aches
- Skin ulcers or open sores in severe cases
Some people experience mild symptoms that come and go over time. Others may have more persistent or severe inflammation. Early symptoms can be easy to miss or mistake for other skin conditions.

Causes and risk factors
Panniculitis can develop from many different triggers and underlying conditions. Some cases are linked to infections, autoimmune diseases, or enzyme deficiencies like Alpha-1-Antitrypsin Deficiency. Other cases may result from physical trauma, cold exposure, or certain medications. In some instances, doctors cannot identify a clear cause.
Risk factors include having inflammatory disorders, pancreatic disease, or certain blood conditions. Women are more likely to develop panniculitis than men. A history of injuries to fatty tissue or exposure to extreme cold can also increase your risk. Some medications, including birth control pills and certain antibiotics, may trigger the condition in susceptible people.
How it's diagnosed
Diagnosing panniculitis typically requires a skin biopsy, where a small tissue sample is examined under a microscope. Your doctor will also review your medical history and perform a physical examination. Blood tests can help identify underlying conditions that may be causing the inflammation.
Testing for Alpha-1-Antitrypsin levels may be recommended if your doctor suspects enzyme deficiency. Additional blood work can check for signs of infection, autoimmune disorders, or pancreatic problems. Talk to your doctor about which tests are appropriate for your situation. They can guide you through the diagnostic process and help identify the root cause.
Treatment options
- Rest and elevate affected areas to reduce swelling and pain
- Apply cool compresses to ease discomfort and inflammation
- Take nonsteroidal anti-inflammatory drugs like ibuprofen for pain relief
- Use corticosteroid medications to reduce severe inflammation
- Treat underlying infections with antibiotics if bacteria are present
- Address enzyme deficiencies with replacement therapy when needed
- Avoid triggers like cold exposure or medications that worsen symptoms
- Work with a specialist for cases related to autoimmune or systemic diseases
- Consider immunosuppressive medications for persistent or severe cases
Frequently asked questions
Panniculitis typically appears as red or purple tender lumps under the skin. These nodules can range from small bumps to larger masses several inches wide. The affected areas may feel warm and firm to the touch. Over time, the lumps may fade, leaving bruise-like discoloration.
The severity of panniculitis varies depending on the underlying cause and extent of inflammation. Many cases are mild and resolve with treatment. However, some types can be associated with serious systemic diseases that require ongoing medical care. Early diagnosis and proper treatment help prevent complications.
Some cases of panniculitis may resolve without treatment, especially if triggered by a temporary factor. However, many cases require medical intervention to address the underlying cause and prevent recurrence. Without treatment, the condition can become chronic or lead to skin damage. Consulting a doctor is important for proper management.
Blood tests help identify underlying causes rather than directly diagnosing panniculitis. Tests may include Alpha-1-Antitrypsin levels, complete blood count, inflammatory markers, and pancreatic enzymes. Your doctor may also order tests for autoimmune conditions or infections. A skin biopsy remains the primary diagnostic tool.
Low levels of Alpha-1-Antitrypsin, an enzyme that protects tissues from inflammation, can lead to panniculitis. When this enzyme is deficient, the body may develop inflammation in various tissues including subcutaneous fat. Testing Alpha-1-Antitrypsin levels can help identify this as a potential cause. Treatment may involve enzyme replacement therapy.
Healing time varies based on the cause and severity of panniculitis. Mild cases may improve within a few weeks with rest and medication. More severe or chronic cases can take months to fully resolve. Some people experience recurring episodes that require ongoing management.
Prevention depends on identifying and avoiding triggers when possible. If you have a known enzyme deficiency or autoimmune condition, managing that condition can reduce flare-ups. Protecting your skin from trauma and extreme temperatures may help. Avoiding medications known to trigger your symptoms is also important.
Rest and elevation of affected areas can reduce swelling and discomfort. Maintaining a healthy weight reduces stress on subcutaneous fat tissue. Avoiding cold exposure and physical trauma to vulnerable areas helps prevent flare-ups. Managing underlying conditions through diet, medication, and regular medical care is essential.
See a doctor if you notice painful lumps under your skin that do not improve within a few days. Seek immediate care if you develop fever, severe pain, or skin ulcers. If you have a diagnosed case that worsens or does not respond to treatment, contact your healthcare provider. Early intervention can prevent complications.
Some types of panniculitis can cause skin changes or scarring, especially if left untreated. Areas of inflammation may leave behind areas of skin depression or discoloration. In severe cases, ulcers can develop and lead to scarring. Prompt treatment helps minimize the risk of permanent damage.
