Skin Cyst: Causes, Signs, and Treatment

A skin cyst is a noncancerous growth that forms beneath the skin. It is a closed sac filled with fluid, pus, or other material. Skin cysts can vary in size and are usually slow-growing. The primary impact of a skin cyst on health is mainly cosmetic and may cause discomfort due to its appearance or location on the body. In most cases, skin cysts do not pose a serious health risk but can affect a person's self-esteem or confidence.

Skin cysts typically present as small bumps beneath the skin's surface. These growths are usually painless and can be felt as round or oval lumps. Skin cysts may vary in size and feel firm or soft to the touch.

Pilar Cyst: These cysts form from hair follicles and are usually found on the scalp. They are typically smooth, round, and filled with a protein called keratin.
Miflia: Small, white cysts that form when dead skin cells get trapped near the surface of the skin. They are often seen on the face, particularly around the eyes and cheeks.
Dermoid Cyst: These cysts are present at birth and can contain tissues such as hair, skin, and teeth. They are typically found near the skull, brain, or spinal cord.
Ganglion Cyst: These cysts are filled with a jellylike fluid and commonly occur near joints or tendons in the hands and wrists. They can cause pain or discomfort but are usually benign.

Incision and Drainage: A healthcare provider may make a small cut in the skin to drain the cyst, relieving pain and pressure.
Injection of Steroid Medication: Steroid injections can help reduce inflammation and shrink the cyst over time.
Laser Treatment: Laser therapy can be used to remove the cyst and prevent recurrence by destroying the cyst wall.
Cryotherapy: Freezing the cyst with liquid nitrogen can help shrink and eliminate it.
