Panniculitis is a disorder that causes painful, red bumps to form on the skin, most often on the legs and feet.
Panniculitis is a condition that causes painful bumps (nodules) to form just underneath the skin. These bumps lead to inflammation (swelling) in the fat layer under the skin, which is known as the panniculus. The panniculus is the type of fat that provides insulation for the body and helps control body temperature.
Types of panniculitis that can affect children include:
Cold panniculitis – affects areas of the body that have been exposed to extreme cold
Erythema nodosum – causes painful, red bumps on the front of the lower legs
Lipodermatosclerosis – causes vein problems and obesity
Subcutaneous sarcoidosis – caused by sarcoidosis (condition that causes inflammatory cells to form unnaturally in various organs throughout the body)
There are many potential causes of panniculitis, including:
A child is at a higher risk for developing panniculitis if they have an infection, an inflammatory disease or a connective tissue disorder. This condition more often affects females than it does males.
