What’s Causing This Cyst?
A cyst is a small pocket of tissue often filled with fluid or pus. It can occur due to an injury, infection, or other issues. They’re usually benign but may need treatment for complications.
Cysts can vary in appearance depending on their type and location. Here are 11 types of cysts.
Epidermoid cyst

Epidermoid cysts are small, benign bumps filled with keratin. Kertain is a protein that’s essential in forming your skin, hair, and nails. Epidermoid cysts occur when something blocks hair follicles, and skin cells build up beneath this blockage.
These cysts can look like a skin-colored, tan, or yellowish bump filled with thick material. They typically occur on your face, neck, or torso, but can occur across your body.
