Nodular Nonsuppurative Panniculitis: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Nodular Nonsuppurative Panniculitis?
A primary care doctor is usually the first doctor people see. Because this condition is rare, care often involves a dermatologist or a rheumatologist. The dermatologist often does the biopsy, and the rheumatologist may manage immune-calming medicines. A direct primary care or concierge doctor can be a good first stop, since longer visits help with rare conditions, and they can order tests and refer you to a specialist.
What it is
Nodular nonsuppurative panniculitis is a rare condition that causes painful lumps under the skin. Panniculitis means swelling of the panniculus, the layer of fat just beneath the skin. Nodular means the swelling forms round bumps called nodules, and nonsuppurative means the lumps do not fill with pus. Doctors also call this condition Weber-Christian disease. Inflamed fat can break down and sometimes affect other parts of the body.
Symptoms
The main sign is tender, red bumps under the skin, most often on the legs and sometimes on the arms or trunk. The lumps are usually one to two centimeters wide. Some people also feel fever, tiredness, muscle aches, or joint pain. The inflammation can sometimes reach organs such as the liver, lungs, or bone marrow, causing more serious problems.
Causes and who gets it
Doctors do not fully know what causes this condition. It seems to involve the immune system attacking the body's own fat tissue, and it has been linked to infections, certain medicines, injuries, and other immune diseases. It is rare and most often appears in adults.
How doctors diagnose it
There is no single test for this condition, so doctors rule out other causes first. They examine the lumps, ask about symptoms, and order blood tests. The key test is a skin biopsy, removing a small piece of the lump for lab examination.
Treatment
Treatment depends on how severe the condition is. Mild cases may only need anti-inflammatory medicines such as NSAIDs to ease pain and swelling. More serious cases may need medicines that calm the immune system, such as corticosteroids. Doctors also treat any underlying cause and watch patients over time because flares can come back.
When to see a doctor
See a doctor if you notice new, painful, or red lumps under your skin that do not go away. Get care quickly if lumps come with fever, tiredness, or unexplained weight loss. If you already have this condition, call your doctor if lumps spread or you feel much more unwell.
Common questions
Is nodular nonsuppurative panniculitis contagious?
No. It is not an infection you can catch or spread to others. It involves inflammation inside the body's own fat tissue.
Does it go away on its own?
Sometimes the lumps fade over weeks, but the condition can also come back in flares. Doctors cannot predict how it will behave in any one person, so follow-up care matters.
Is it cancer?
No. It is an inflammatory condition, not cancer. However, doctors do tests such as a biopsy to make sure the lumps are not caused by something else.
Can I treat it at home?
Home care cannot treat the underlying inflammation. You should see a doctor for any new, painful lumps under the skin so the cause can be checked properly.
