Traumatic anserine folliculosis (TAF) is a skin condition that results from damage or trauma to the hair follicles. It is characterized by the appearance of small, red, itchy bumps or pustules around the hair follicles on the thighs and buttocks, and may also involve the lower legs. In this article, we will discuss in detail the definitions, causes, symptoms, and treatments of TAF.
Definitions and Types:
Traumatic anserine folliculosis is also known as anserine folliculosis, folliculitis decalvans, and perifolliculitis capitis abscedens et suffodiens. These terms all refer to the same condition but may be used differently based on the location of the affected hair follicles.
Folliculitis decalvans is a type of TAF that affects the hair follicles on the scalp. It is characterized by pustules and scarring that can lead to permanent hair loss in the affected area.
Perifolliculitis capitis abscedens et suffodiens (PCAS) is a more severe form of TAF that also affects the scalp. It is characterized by large, painful nodules that can result in severe scarring and hair loss.
Causes
The pathogenesis of TAF is not fully understood, but it is believed to be a result of trauma or friction to the skin.
Here are 20 potential causes of traumatic anserine folliculosis:
- Friction: The most common cause of TAF is friction between the skin on the lateral aspect of the thighs and clothing, such as tight-fitting pants, shorts, or underwear.
- Exercise: Repetitive friction and pressure caused by activities that involve running, cycling, or any other exercise that involves repetitive leg movements can also cause TAF.
- Obesity: Obese individuals are more prone to TAF due to increased pressure and friction on the lateral aspect of the thighs.
- Poor hygiene: Poor hygiene can lead to the accumulation of sweat, sebum, and bacteria in the hair follicles, which can cause inflammation and subsequent TAF.
- Shaving: Shaving can irritate hair follicles and lead to TAF.
- Tight clothing: Wearing tight clothing, especially in hot and humid conditions, can increase friction and pressure on the skin, leading to TAF.
- Medications: Certain medications, such as steroids and immunosuppressants, can weaken the immune system and make the skin more susceptible to TAF.
- Diabetes: Individuals with diabetes are at a higher risk of developing TAF due to their impaired immune system.
- HIV: Individuals with HIV are more prone to developing TAF due to their weakened immune system.
- Irritant contact dermatitis: Exposure to irritants such as detergents, solvents, or chemicals can irritate the skin and lead to TAF.
- Atopic dermatitis: Individuals with atopic dermatitis are more prone to TAF due to the weakened skin barrier.
- Psoriasis: Psoriasis can weaken the skin barrier, making the skin more susceptible to TAF.
- Pityriasis rubra pilaris: This rare skin condition can cause follicular papules and pustules similar to TAF.
- Acne: Acne can also cause follicular papules and pustules similar to TAF.
- Folliculitis: Folliculitis is a common skin condition characterized by inflammation of the hair follicles, which can lead to TAF.
- Ingrown hairs: Ingrown hairs can irritate the hair follicles and cause TAF.
- Yeast infections: Yeast infections can cause inflammation of the hair follicles and lead to TAF.
- Heat rash: Heat rash can cause inflammation of the hair follicles, leading to TAF.
- Allergic reactions: Allergic reactions to clothing or other materials in contact with the skin can lead to TAF.
- Insect bites: Insect bites can lead to inflammation of the hair follicles and cause TAF.
Symptoms
It is characterized by the formation of small, painful, pus-filled bumps on the skin that develop in the area surrounding the hair follicles. These bumps may be accompanied by other symptoms such as redness, itching, and tenderness. In this article, we will discuss in detail the 20 symptoms of traumatic anserine folliculosis.
- Pus-filled bumps: The primary symptom of traumatic anserine folliculosis is the formation of small, painful, pus-filled bumps on the skin. These bumps can appear anywhere on the body where hair grows, but are most commonly found on the lower legs, thighs, and buttocks.

Diagnosis
Most potential diagnoses and tests that can help in the diagnosis of traumatic anserine folliculosis, as well as provide a detailed explanation of each of these diagnoses and tests.
- Clinical examination: The first step in diagnosing traumatic anserine folliculosis is a clinical examination, where a dermatologist will examine the affected area of the skin. The dermatologist will look for the presence of small bumps or pustules around the hair follicles, as well as signs of inflammation, redness, and tenderness.
- Skin biopsy: A skin biopsy involves taking a small sample of skin tissue from the affected area and examining it under a microscope. This can help to confirm the diagnosis of traumatic anserine folliculosis and rule out other skin conditions that may have similar symptoms.
- Culture and sensitivity test: A culture and sensitivity test involves taking a sample of the pus or fluid from the bumps and testing it in a laboratory to determine the type of bacteria present and the antibiotics that can effectively treat the infection.
- Gram stain: A Gram stain involves staining a sample of the pus or fluid from the bumps and examining it under a microscope. This can help to identify the type of bacteria present and guide treatment.
- KOH preparation: A KOH preparation involves taking a sample of the skin and treating it with potassium hydroxide to dissolve the skin cells and reveal any fungal elements that may be present. This can help to rule out fungal infections that can mimic the symptoms of traumatic anserine folliculosis.
- Skin scraping: A skin scraping involves taking a sample of the skin and examining it under a microscope to look for the presence of mites or other parasites that may be causing the symptoms.
- Tzanck smear: A Tzanck smear involves taking a sample of the fluid from the bumps and examining it under a microscope to look for the presence of herpes simplex virus, which can cause a similar skin condition.
- Skin prick test: A skin prick test involves injecting a small amount of the suspected allergen under the skin and monitoring for an allergic reaction. This can help to identify any underlying allergies that may be contributing to the development of the skin condition.
- Patch test: A patch test involves applying a small amount of the suspected allergen to the skin and monitoring for an allergic reaction over a period of 48-72 hours. This can help to identify any delayed hypersensitivity reactions that may be contributing to the development of the skin condition.
