Nodular Nonsuppurative Panniculitis

Nodular nonsuppurative panniculitis describes a rare group of skin disorders characterized by tender, painful bumps below the surface of the skin (subcutaneous nodules) that usually lead to inflammation of the subcutaneous layer of fat (panniculitis). These nodules tend to be 1-2 centimeters in length and most often affect the legs and feet. In most people, this condition is associated with fever, a general feeling of ill health (malaise), muscle pain, and/or abdominal pain. These symptoms may subside after a few days or weeks and may recur weeks, months, or years later. The exact cause of nodular nonsuppurative panniculitis is unknown.
