Cyst Removal

A skin cyst, also known as an epidermal cyst or sebaceous cyst, is a closed sac that forms just beneath the skin. These cysts are typically slow-growing and benign, often containing a semi-fluid or cheesy material called keratin. The formation of a skin cyst begins when the cells of the skin's outer layer, known as the epidermis, multiply abnormally and move deeper into the skin instead of shedding normally. This process can be triggered by a variety of factors, including blockages of hair follicles, trauma to the skin, or a buildup of keratin.

As these abnormal skin cells continue to multiply, they form a sac, or cyst, beneath the skin's surface. This sac is lined with epithelial cells, which are the same type of cells that make up the epidermis. The sac gradually fills with keratin and other debris, forming a semi-solid or fluid-filled mass. Over time, the cyst may enlarge, causing a noticeable bump beneath the skin. Skin cysts can occur anywhere on the body but are most commonly found on the face, neck, chest, and back. They are typically round or oval in shape and may be firm or slightly soft to the touch, depending on the contents of the cyst. In some cases, a cyst may become inflamed or infected, causing pain, redness, and swelling.

Epidermal cyst can be surgically removed. Usually a minor skin surgery is done under local anesthesia. The whole cyst, together with the cyst wall be removed to prevent recurrence, then the wound would be sutured. Skin sutures are removed after 10-14 days after the surgery.
