Trichilemmal cysts are a common medical condition, but there can still be confusion regarding their causes, symptoms, and treatment. We’ll delve into that confusion here to make sure you have all the information you need to understand trichilemmal cysts and make an informed decision about your health. We’ll explore what trichilemmal cysts are, what causes them, the symptoms they can produce, and the best ways to treat them. By the end of this article, you'll know everything there is to know about trichilemmal cysts!
A trichilemmal cyst, also known as a pilar cyst or isthmus-catagen cyst, is a benign growth that commonly forms on the scalp. These cysts are filled with keratin, the same protein that makes up hair and nails, and they have a central depression that drains onto the surface. Trichilemmal cysts are usually round or oval and range in size from a pea to a golf ball. While they can occur at any age, they are most common in middle-aged women.
There are several theories about what causes trichilemmal cysts, but the most likely explanation is that they develop from hair follicles that become plugged with keratin. This can happen as a result of trauma to the follicle, such as from brushing or combing too aggressively. Cysts may also be caused by an overgrowth of skin cells around the hair follicle.
Symptoms of trichilemmal cysts include slowly enlarging lumps on the scalp that may be tender to touch. The central depression may drain pus or bloody fluid if ruptured. In some cases, multiple cysts may cluster together and form larger growths.
While trichilemmal cysts are usually benign, they can sometimes become infected and cause serious complications. If you have any concerns about a lump on your scalp, it's important to see a doctor for evaluation.
There are several possible causes of trichilemmal cysts, though the exact cause is unknown. One theory is that the cysts form when the outer layer of skin (the stratum corneum) breaks down and allows the inner layer of skin (the dermis) to bulge out. This can happen due to trauma or repeated rubbing or scratching of the skin. Another theory is that the cysts form when a buildup of keratin—a protein that makes up the outer layer of skin—occurs in the hair follicles.
Whatever the cause, trichilemmal cysts are not contagious and are not cancerous.
Symptoms of Trichilemmal Cysts
There are a few different symptoms that are associated with trichilemmal cysts. One of the most common is a lump or bump that forms on the scalp. This lump is usually small, but it can grow larger over time. It may be painful or itchy, and it can sometimes bleed. In some cases, the cyst can rupture and release a thick, white substance. Other symptoms include hair loss, scalp irritation, and changes in the texture of the skin around the cyst.
A trichilemmal cyst is a type of benign, or non-cancerous, growth that can develop on the scalp. Though they’re most often found on the head, they can also occur on other areas of the body where hair follicles are present, such as the face, neck, and genitals.
These cysts are also known as wen or sebaceous cysts. They’re filled with a cheese-like substance called keratin, which is produced by the hair follicles.
Trichilemmal cysts are usually small — about 1 centimeter in diameter — and feel like a smooth, round lump under the skin. They’re usually not painful unless they become infected.
Infected trichilemmal cysts can be red, swollen, and painful to the touch. If you have an infected cyst.
Most trichilemmal cysts go away on their own without treatment. However, if a cyst becomes large or uncomfortable, your doctor may recommend removing it surgically.
Trichilemmal cysts are relatively common and can be treated with relative ease. It is important to recognize the signs of a trichilemmal cyst, as they can become infected if left untreated. If you think that you might have a trichilemmal cyst. With proper care, these small lumps should subside after a short period of time.
