Epidermoid Cyst

An epidermoid cyst, also known as a sebaceous cyst, is a benign, non-cancerous growth commonly found on the skin. These cysts typically develop when cells from the top layer of the skin (epidermis) are trapped beneath the skin's surface, often due to a blocked hair follicle or an injury to the skin. As these cells continue to multiply, they form a cyst filled with a yellow, cheesy material called keratin.

Epidermoid cysts are usually slow-growing and painless, and they can occur almost anywhere on the body. They are more common on the face, neck, chest, back, and genitals. Some key characteristics of epidermoid cysts include:

Size: They can vary in size from small, pea-sized cysts to larger growths.

Appearance: The cysts often have a raised, dome-like appearance with a central punctum or opening.

Texture: The cyst's contents are typically thick and can be expressed (squeezed out) when pressure is applied.

Mobility: They are usually mobile and can be moved around under the skin.

Epidermoid cysts are generally harmless, but they may become inflamed or infected if they rupture or if bacteria enter the cyst. In such cases, they can cause pain, redness, and swelling. If you suspect an infection or have concerns about an epidermoid cyst, it's essential to seek medical attention. A healthcare provider can drain and treat an infected cyst, and they may recommend surgical removal for larger or symptomatic cysts.

Surgical removal is typically a straightforward procedure and can be done in a doctor's office or clinic. It involves making a small incision, draining the cyst, and removing the cyst wall to prevent recurrence.

It's important not to attempt to remove or pop an epidermoid cyst at home, as this can lead to infection, scarring, and complications. If you notice a new growth on your skin or have concerns about an existing one, it's best to consult a healthcare professional for proper evaluation and treatment.
