What is Sebaceous Cyst?

A sebaceous cyst is a type of benign (non-cancerous) lump that can develop just beneath the skin’s surface. The cysts form as a result of a blockage in the sebaceous gland, which is responsible for producing sebum, an oily substance that helps keep the skin moisturized. When the gland is blocked, the sebum builds up and forms a cyst.

Sebaceous cysts can occur anywhere on the body, but they are most commonly found on the face, neck, and upper trunk. They can range in size from a small, pea-sized bump to a large, visible cyst that is several centimeters in diameter. Sebaceous cysts are usually smooth, round, and moveable, and they often have a yellowish appearance due to the build-up of sebum.

Sebaceous cysts are usually harmless and do not cause any pain or discomfort, unless they become infected. In some cases, the cysts can become red, tender, and painful, indicating that an infection has occurred. If an infection does occur, it is important to seek medical treatment as soon as possible, as the infection can spread and cause more serious health problems.

Diagnosis of a sebaceous cyst is typically based on a physical examination and the appearance of the cyst. In some cases, a biopsy may be performed to rule out the possibility of skin cancer or other more serious conditions.

Treatment for sebaceous cysts typically involves surgical removal. This can be done through a simple procedure that involves making a small incision in the cyst and draining the contents. The cyst is then removed, and the incision is closed with sutures or a skin adhesive.

In some cases, a sebaceous cyst may be drained using a needle, but this is typically not recommended as it can increase the risk of infection and may not provide a permanent solution. In addition, some people may opt to leave their sebaceous cysts alone, especially if they are not causing any discomfort or are not noticeable.

In conclusion, a sebaceous cyst is a type of benign lump that forms as a result of a blockage in the sebaceous gland. The cysts are usually harmless, but they can become infected and cause pain, redness, and tenderness. Treatment for sebaceous cysts typically involves surgical removal, and it is important to seek medical treatment if an infection occurs. If you suspect that you have a sebaceous cyst, it is important to seek professional help for proper evaluation and treatment.
