Pilar and Trichodermal Cysts: What Are They and How Are They Treated?
Pilar and trichodermal cysts are benign growths that occur on the scalp. Both types of cysts are formed from hair follicles and are similar in appearance, but they differ in their location and composition.
Pilar cysts are located deeper in the skin and are typically filled with a keratinous material. Trichodermal cysts, on the other hand, are located more superficially and are filled with hair follicles and sebum.
While these cysts are usually harmless, they can become bothersome if they grow larger or become infected. In some cases, they may also cause cosmetic concerns.
Symptoms of Pilar and Trichodermal Cysts
The symptoms of pilar and trichodermal cysts are similar. They typically appear as small, round or oval bumps on the scalp. The bumps may be flesh-colored, yellow, or brown and can range in size from a few millimeters to several centimeters.
In some cases, the cysts may be tender or painful to the touch, especially if they become infected. They may also cause hair loss in the surrounding area.
Treatment Options for Pilar and Trichodermal Cysts
If you have a pilar or trichodermal cyst, your doctor may recommend one of several treatment options, depending on the size and location of the cyst.
- Watchful waiting: If the cyst is small and not causing any symptoms, your doctor may recommend simply monitoring it to see if it grows or becomes infected.
- Drainage: If the cyst is causing discomfort or is infected, your doctor may drain it to relieve symptoms.
- Surgical removal: If the cyst is large, causing cosmetic concerns, or has become infected multiple times, your doctor may recommend surgical removal. This procedure is typically done under local anesthesia and involves making a small incision to remove the cyst.
After the cyst is removed, your doctor may recommend antibiotics or other treatments to prevent infection and promote healing.
Preventing Pilar and Trichodermal Cysts
While there is no surefire way to prevent pilar and trichodermal cysts, there are some steps you can take to reduce your risk of developing them. These include:
- Keeping your scalp clean and free of excess oil
- Avoiding tight hairstyles that pull on the hair follicles
- Avoiding picking or scratching at the scalp
