Meta Description: Discover everything about pilar cysts on the scalp: causes, symptoms, diagnosis, treatment options, and prevention tips. Learn how to identify and manage these common benign cysts. This comprehensive guide provides valuable information for understanding and addressing pilar cysts effectively.

What are Pilar Cysts?

Pilar cysts, also known as trichilemmal cysts or wen, are common, slow-growing, benign cysts that develop in the scalp. They form from keratin, a protein that makes up hair and skin. These cysts are usually painless and harmless. However, they can become inflamed or infected, causing discomfort.

Causes of Pilar Cysts on the Scalp

The exact cause of pilar cysts isn't fully understood. However, they're believed to be linked to a blockage in the hair follicle. This blockage prevents the normal shedding of keratin, leading to a buildup and the formation of a cyst. Several factors may increase the risk, including:

• Genetics: A family history of pilar cysts increases your likelihood of developing them.
• Hair Follicle Damage: Trauma or injury to the scalp can potentially contribute to cyst formation.
• Hormonal Changes: Fluctuations in hormones might play a role in some cases.

Symptoms of Pilar Cyst

Pilar cysts typically appear as:

• Small, dome-shaped bumps: They can vary in size, ranging from a few millimeters to several centimeters in diameter.
• Smooth surface: The cyst's surface is usually smooth and firm to the touch.
• Yellowish or skin-colored: Their color often matches your skin tone or may have a slightly yellowish hue.
• Painless (usually): Most pilar cysts are painless unless infected or inflamed.
• Slow growth: They typically grow slowly over time.

Important Note: If you notice any redness, swelling, pain, or discharge from a scalp cyst, seek medical attention immediately, as this could indicate infection.

Diagnosis of Pilar Cysts

Diagnosing a pilar cyst usually involves a simple physical examination by a dermatologist or healthcare professional. They'll assess the cyst's appearance, size, and consistency. In some cases, a biopsy may be necessary to rule out other conditions.

Treatment Options for Pilar Cysts

Treatment is often unnecessary unless the cyst causes discomfort, becomes infected, or is cosmetically bothersome. Options include:

• Observation: If the cyst is small and asymptomatic, your doctor may recommend monitoring it without intervention.
• Surgical Removal: This is the most common treatment. The cyst is surgically excised, ensuring complete removal to prevent recurrence.
• Drainage and Curettage: This involves draining the cyst's contents and then scraping the cyst wall to prevent reformation. However, recurrence is possible with this method.
• Injection: In some cases, injecting corticosteroids into the cyst can reduce inflammation and size.

How to Prevent Pilar Cysts

While there's no guaranteed way to prevent pilar cysts, maintaining good scalp hygiene can help:

• Regular Shampooing: Gently cleanse your scalp regularly to remove excess oil and debris.
• Avoid Harsh Chemicals: Use gentle shampoos and conditioners that don't irritate your scalp.
• Protect Your Scalp: Protect your scalp from injury or trauma.

When to See a Doctor

Consult a dermatologist or healthcare provider if:

• The cyst is painful or inflamed.
• You notice any signs of infection (redness, swelling, pus).
• The cyst is rapidly growing or changing in appearance.
• You have multiple cysts.
• You're concerned about the cyst's appearance.
