Factitial Panniculitis

Factitial panniculitis refers to a group of skin disorders characterized by inflammation of subcutaneous fat, leading to the formation of nodules or bumps under the skin. The term “factitial” means that the cause of the condition is due to deliberate and repeated manipulation of the skin.

Factitial panniculitis, also known as factitial dermatitis, is a type of skin condition that is caused by the intentional or accidental creation of skin lesions through the manipulation or injury of the skin. The word “factitial” means “made by human action,” and “panniculitis” refers to inflammation of the subcutaneous fat layer. Factitial panniculitis can result from various causes, including self-inflicted injury, such as picking at the skin or applying irritants, as well as medical procedures gone wrong, such as injections or biopsies.

Factitial panniculitis, also known as factitial dermatitis, is a condition where a person deliberately causes injury to their own subcutaneous fat tissue, leading to inflammation and a characteristic pattern of skin changes. While the exact cause of this behavior is not well understood, it is thought to be related to a variety of psychological and emotional factors.

There are several types of factitial panniculitis, each with distinct causes, symptoms, and treatments. Here is a list of some of the most common types:

  1. Factitial panniculitis with abscess formation: This type of factitial panniculitis is caused by the introduction of bacteria into the subcutaneous fat, resulting in the formation of abscesses. This type of factitial panniculitis is often seen in individuals who repeatedly inject foreign substances into their skin, such as those who use injected drugs.
  2. Nodular factitial panniculitis: This type of factitial panniculitis is characterized by the formation of nodules or lumps under the skin. The nodules are usually firm and may be tender to the touch. This type of factitial panniculitis is often seen in individuals who repeatedly pinch or squeeze their skin.
  3. Linear factitial panniculitis: This type of factitial panniculitis is characterized by the formation of linear or rope-like lesions under the skin. The lesions are usually the result of repeated skin picking or digging.
  4. Panniculitis with eosinophilia: This type of factitial panniculitis is characterized by the presence of eosinophils, a type of white blood cell, in the affected area. The cause of this type of factitial panniculitis is not well understood, but it may be related to an allergic reaction.
  5. Factitial panniculitis with granuloma formation: This type of factitial panniculitis is characterized by the formation of granulomas, which are collections of immune cells, in the affected area. This type of factitial panniculitis is often seen in individuals who repeatedly inject foreign substances into their skin, such as those who use injected drugs.

Causes

Possible causes of factitial panniculitis:

  1. Malingering: Malingering is the deliberate and intentional production of false or exaggerated physical symptoms for personal gain. This may include financial compensation or to avoid work or other obligations.
  2. Factitious disorder: Factitious disorder is a condition in which a person deliberately and consciously simulates or causes physical or psychological symptoms in themselves without any apparent external incentives or gain.
