Pilar Cysts, also known as Trichilemmal Cysts, are sacs that are externally visible. These smooth outgrowths are filled with fluids and are formed below the skin surface. They are similar to epidermoid cysts that are formed in the inner skin layer. Trichilemmal Cysts are filled with the protein substance “keratin”, which is found in skin, hair and nails, and the fatty matter “sebum” secreted by sebaceous glands.
Approximately 10% people are found to have one or more Pilar Cysts. Around 70% of the Pilar Cyst sufferers are seen to have more than one sac on their skin surface.
One can mostly find Pilar Cysts on scalp. However, they can also be seen in other regions of the body such as ears. There are cases of sebaceous cyst on face. Occasionally, one can also have Pilar Cyst on scrotum.
Pilar Cysts are more common in middle aged women. They are also visible in young people who have just attained puberty and going through hormonal changes. You will rarely notice a Pilar Cyst in children. Since middle aged people are the prime target of Pilar Cyst children are very rarely seen to suffer from it.
Pilar Cysts appear as smooth bumps on the surface of the skin. These have a round, dome-like shape. Pilar Cyst size is normally anywhere between 1 and 5 cm. These are generally white in color or may have the same color as skin. These cysts are usually firm. In a few cases, these can move when pressed by fingers.
The appearance of smooth dome-shaped bumps is not the only symptom of Pilar Cysts. Some of the other major Pilar Cyst symptoms are:
The cysts can become red in appearance if they suffer an infection.
Pilar Cyst pain is common in case of an infection. People with an infected Pilar Cyst usually experience pain o touching the suffering skin region.
If the head shows a Pilar Cyst hair loss may occur in the spot where the bump has grown.
If the cyst somehow suffers damage, pus may ooze out. In such cases of Pilar Cyst rupture, foul smell emanates from the bump. Sebaceous cyst popping or rupture usually occurs after the sac has grown to a considerable size. The rupture is usually followed by an infection as a natural response of the body against foreign bodies.
The person may also experience an irritation when the cysts rub against the clothes. Friction between a tender Pilar Cyst and some other surface can cause this problem.
In some cases, the cyst can grow in size after some months have passed.
In a few cases, a horn may also arise over the bump giving it a further ugly appearance.

The most common causes of Pilar Cyst formation include :
Trichilemmal Cysts can appear if sebaceous glands suffer a blockage due to some reason.
The bumps can arise if there is an inflammation of the hair follicles. A swelling of the follicles leads to a buildup of keratin compound and gives rise to bumps.
Trichilemmal Cysts are sometimes inherited from parents. The condition is transmitted from parents to offspring through genes. Children of parents affected by this disease can also have it sometime in their lives.
Pilar Cysts can also arise if the skin suffers an injury. A skin trauma in a particular part of the body leads to an accumulation of keratin compound in the affected region thus forming fleshy lumps.
Excessive production of the male hormone testosterone can also be one of the major causes of this disorder. This is the reason why Pilar Cysts are often found in youngsters who have just achieved puberty.
Pilar Cyst is a lot like Epidermoid Cyst in appearance. However, these are different conditions that slightly vary in nature. The variation can mainly be observed under a microscope. The lining of Epidermoid Cysts appears as the epidermal layer or the outermost cell layer of the skin. However, Pilar Cyst lining consists of cells that are similar to those found at the base of hairs.
Epidermoid Cysts affect young and middle aged people. But Pilar Cysts are noticeable more in women than men. They appear in middle aged women.
Earlier, both Epidermoid and PIlar Cysts were wrongly referred to as “Sebaceous Cysts”.
Pilar Cyst treatment is generally not necessary. Small cysts do not require any medical attention as they normally get resolved after a point of time. But medical cure is necessary if the cyst continues to grow in size or if there is pain or infection in the bump.
In case of a Pilar Cyst infection, doctors normally recommend the use of antibiotics. Antibiotic drugs like Erythromycin and Cloxacillin are usually used for curing an Infected Pilar Cyst.
In rare cases, Pilar cyst surgery may be necessary. This is needed if the bump is already very big in size or is a constantly growing one. For an immediate treatment of Pilar Cyst on scalp removal by operation is the best procedure. Surgery helps complete Pilar Cyst removal. However, a scar may remain for a long time at the point where a Pilar Cyst excision has been carried out.
Draining a sebaceous cyst is also quite useful in curing infected cysts or large cysts. This is done by using a local anesthetic. An incision is made to release the fluid accumulated in the lump. This improves the situation and cures the sac without forming scars.
Little information is available about Pilar Cyst natural treatment. The condition requires professional medical care and Pilar Cyst home remedy is not advised by doctors.
It is not possible to avoid the disease. However, young people can try regular exercise to keep the condition at bay. Exercise can help maintain a hormonal balance within the body and prevent Pilar Cyst formation due to over-production of testosterone. Proper hair care on a daily basis can also avoid any damage of hair follicles.
