Pilar cyst

What is Pilar cyst?

A pilar cyst, also known as a trichilemmal cyst, is a small, usually harmless lump that forms under the skin, often on the scalp. It is caused by a buildup of keratin, a protein found in skin cells. Pilar cysts are often multiple and may be inherited. They can become inflamed or infected, requiring medical attention. According to the National Institute for Health and Care Excellence (NICE) guidelines, pilar cysts are a common condition, affecting up to 10% of the population.

Causes and Risk Factors

Pilar cysts are caused by a buildup of keratin, a protein found in skin cells. The exact cause of this buildup is not fully understood, but it is thought to be related to genetic factors, as pilar cysts often run in families. Other risk factors include:

• Family history: If you have a family history of pilar cysts, you are more likely to develop them.
• Age: Pilar cysts can occur at any age, but they are most common in adults.
• Skin conditions: Certain skin conditions, such as eczema or psoriasis, may increase the risk of developing pilar cysts.
• Lifestyle: Poor skin hygiene and trauma to the skin may also contribute to the development of pilar cysts.

Signs and Symptoms

The signs and symptoms of pilar cysts can vary, but they often include:

• A small, firm lump under the skin, usually on the scalp
• Inflammation or redness around the lump
• Discharge or pus from the lump
• Itching or tenderness around the lump
• Hair loss or thinning around the lump In the early stages, pilar cysts may not cause any symptoms, but as they grow, they can become inflamed or infected, leading to increased redness, swelling, and discharge.

How is Pilar cyst Diagnosed?

Pilar cysts are usually diagnosed based on a physical examination and medical history. Your doctor may perform a visual examination of the lump and ask questions about your symptoms and medical history. In some cases, imaging tests, such as an X-ray or ultrasound, may be ordered to rule out other conditions. According to the Mayo Clinic, a biopsy may also be performed to confirm the diagnosis.

Treatment Options

The treatment of pilar cysts depends on the size, location, and symptoms of the cyst. Treatment options include:

• Observation: Small, asymptomatic cysts may not require treatment.
• Warm compresses: Applying a warm compress to the affected area may help reduce inflammation and promote drainage.
• Antibiotics: If the cyst becomes infected, antibiotics may be prescribed to treat the infection.
• Surgical removal: Large or inflamed cysts may need to be surgically removed. This is usually a minor procedure that can be performed under local anesthesia.
• Laser therapy: In some cases, laser therapy may be used to remove the cyst.

Home Care and Self-Management

There are several things you can do at home to help manage pilar cysts:

• Keep the skin clean and dry to prevent infection.
• Apply warm compresses to the affected area to reduce inflammation and promote drainage.
• Avoid picking or scratching the lump, as this can lead to infection and scarring.
• Use gentle skin care products and avoid irritants, such as harsh soaps or exfoliants.

Prevention Strategies

While it is not possible to completely prevent pilar cysts, there are several things you can do to reduce your risk:

• Practice good skin hygiene, including keeping the skin clean and dry.
• Avoid trauma to the skin, such as cuts or scrapes.
• Manage underlying skin conditions, such as eczema or psoriasis.
• Avoid irritants, such as harsh soaps or exfoliants.
