Unveiling the Mystery: What is a Pilar Cyst?
Pilar cysts are a common type of cyst that form on the scalp, but may also grow on other parts of the body. They are also known as trichilemmal cysts or wens. These cysts are usually slow-growing, and it can take years for them to reach a noticeable size. Pilar cysts may be genetic, and if one family member has had it, other members of the family may also develop it. This article aims to provide you with a comprehensive understanding of pilar cysts.
The Anatomy of Pilar Cysts
Pilar cysts often form from the hair follicles on the scalp. They can be seen as small, round bumps that have a smooth appearance. These cysts are usually filled with keratin, which is a protein that is found in hair and nails. Pilar cysts are usually firm to the touch and can be moved under the skin.
Why Do Pilar Cysts Form?
There is no known cause of pilar cysts, but they typically form due to the hair follicle cells being damaged or traumatized. There are also theories that suggest that genetics may play a role in the formation of these cysts.
Who is at Risk for Developing Pilar Cysts?
Anyone can develop a pilar cyst, but they tend to be more common in middle-aged women. Family history is also a risk factor for pilar cysts, as they tend to run in families.
How Are Pilar Cysts Diagnosed?
A dermatologist can diagnose a pilar cyst by conducting a physical exam of the affected area. They may also take a sample of the cyst to examine it under a microscope. A biopsy may be done to rule out any other conditions.
Treatment Options for Pilar Cysts
In many cases, pilar cysts do not require treatment, and the individual may choose to leave them alone. However, if the cyst is causing discomfort or is unsightly, there are options for treatment.
Surgical Removal
The most common form of treatment for pilar cysts is surgical removal. This is a routine outpatient procedure that can be done under local anesthesia. The dermatologist will use a scalpel to make a small incision and remove the cyst. The incision is then closed with sutures or adhesive strips.
Laser Removal
Another option for removing pilar cysts is through the use of lasers. Laser removal is a quick and painless procedure that involves using a beam of light to break up the cyst. This type of treatment is often less invasive than surgical removal and may result in less scarring.
Cortisone Injections
In some cases, cortisone injections may be used to reduce the size of a pilar cyst. This treatment involves injecting a small amount of corticosteroids directly into the cyst. The medication helps to reduce inflammation around the cyst, which can lead to a decrease in the size of the cyst.
Preventing Pilar Cysts
Since the cause of pilar cysts is unknown, there are no known preventive measures. However, individuals with a family history of pilar cysts may want to consider being proactive in their skin care routines. It’s important to protect the scalp from trauma, which can lead to the development of cysts.
When to See a Dermatologist
If you notice a lump on your scalp or any other area of your body, it’s important to see a dermatologist as soon as possible. While pilar cysts are usually harmless, there is a small risk that they could be something more serious.
The Bottom Line
Pilar cysts are a common condition that affects many people. While they are usually harmless, they can be a cause for concern if they are causing discomfort or are unsightly. If you have a cyst that is bothering you, it’s important to talk to a dermatologist to discuss your options.
