Folliculitis Decalvans, Know Its Consequences

Folliculitis decalvans is a rare and chronic condition that affects the scalp and hair follicles, causing ongoing inflammation and scarring which leads to permanent hair loss. This condition is typically caused by a bacterial infection that triggers an immune response and subsequent hair loss. Pustules, or pus-filled bumps, can form on various parts of the body, but in folliculitis decalvans they tend to be more persistent and difficult to treat. It is important to seek prompt medical attention from a dermatologist if you suspect you may have folliculitis or any other skin condition to prevent the progression of the condition and minimize hair loss.

What Causes Folliculitis Decalvans?

Folliculitis decalvans is a chronic condition that results in permanent hair loss and scarring due to inflammation of the hair follicles. The specific cause of this condition is not entirely clear, but Staphylococcus aureus (Staph A) infection is believed to be a contributing factor. Staph A is commonly found on the skin and in the nose of people and is generally harmless. In some cases, however, it can trigger an abnormal immune response leading to chronic inflammation of hair follicles and hair loss.

Genetic factors, hormonal imbalances, stress, and environmental factors are all potential contributors to this condition. Folliculitis decalvans can be challenging to diagnose as it shares symptoms with other skin conditions. Antibiotics are often prescribed to treat the underlying staph infection, while anti-inflammatory drugs help to reduce inflammation and immunosuppressive drugs suppress the immune response.

While there is no permanent cure for folliculitis decalvans, early diagnosis and treatment can help slow the progression of the disease and minimize hair loss. It is important to have regular follow-up appointments with a dermatologist to monitor the condition and modify treatment as required.

What Are The Risk Factors?

Folliculitis decalvans is a chronic inflammatory condition that affects hair follicles on the scalp, leading to hair loss. Although it is a relatively rare condition, it can have a significant impact on the affected individual’s self-esteem and quality of life.

Folliculitis decalvans typically develop during the teenage years or early adulthood, although it can occur at any age. While the exact cause of this condition is unknown, there are several risk factors that increase the likelihood of developing folliculitis decalvans. These include a history of bacterial or fungal infections, a weakened immune system, and the presence of other skin conditions such as acne or rosacea. Additionally, certain genetic factors may also play a role in the development of this condition.

The symptoms of folliculitis decalvans include inflammation, pustules, or papules around the hair follicles, and hair loss. The condition can be progressive, leading to the destruction of the hair follicles and permanent hair loss. A diagnosis of folliculitis decalvans is typically made based on a physical exam and a biopsy of the affected area.

Symptoms

The condition typically presents as the formation of round or oval-shaped bald patches on the scalp. However, in rare cases, it can affect other areas of the body such as the armpits, genitals, face, legs, and arms.

The symptoms of folliculitis decalvans can vary from person to person, but some common ones include an itchy scalp that resembles dandruff or seborrheic dermatitis. The scalp may also feel tight or painful. Pustules, which are small, pus-filled bumps, most commonly appear on the back of the head but can occur anywhere on the scalp. After the pustules ooze, they may form scabs, and scaly skin may be present.

One of the unique features of folliculitis decalvans is that it causes hair to grow in tufts, with multiple strands of hair originating from the same follicle. This gives the appearance of “tufts” of hair, which is why the condition is sometimes referred to as tufted folliculitis. As the condition progresses, the hair follicles eventually die, leading to the formation of scar tissue and bald spots.

While the cause of folliculitis decalvans is not fully understood, it is believed to be related to an abnormal immune response to bacteria that normally live on the skin. The condition is more common in men than women and typically develops in early adulthood.

How Is Diagnosed?

The condition can be challenging to diagnose as its symptoms can resemble other skin conditions such as psoriasis or eczema. Therefore, seeking medical attention from a dermatologist is crucial to obtain an accurate diagnosis.

During the diagnostic process

the dermatologist will conduct a comprehensive examination of the scalp, focusing on areas with hair loss, redness, swelling, and pustules. The healthcare provider will use a magnifying device to get a clear view of the pustules and examine their size, shape, and distribution. Additionally, the dermatologist may gently squeeze the pustules to extract some of the fluid for laboratory testing.

Collected fluid

Is checked for the presence of Staphylococcus aureus (Staph A), a type of bacteria that frequently causes skin infections. This bacterium is often the underlying cause of folliculitis decalvans, so detecting its presence is crucial to confirm the diagnosis. The dermatologist may also conduct a bacterial culture, which involves growing bacteria from the collected sample in the laboratory to determine the exact type of bacteria causing the infection.

To rule out other conditions that can mimic the symptoms of folliculitis decalvans, the healthcare provider may perform additional tests. One such test is a fungal culture, where the dermatologist scrapes a small amount of skin and hair from the scalp to check for the presence of ringworm, a fungal infection that can cause hair loss and scalp inflammation. The healthcare provider may also perform a skin biopsy, which involves taking a small sample of skin tissue from the affected area, to confirm the diagnosis.

Overall, diagnosing folliculitis decalvans requires a thorough examination of the scalp by a dermatologist, along with various tests to rule out other conditions and confirm the presence of Staph A, the underlying cause of this hair loss disorder. Prompt diagnosis and treatment can help prevent further hair loss and scarring.
