Yes they can, I have gone to my family doctor and have been diagnosed with an epidermoid cyst in the lower part of my belly button. At first it was a purplish-blue color and recently it got infected and flared up into something that looked like a boil. An epidermoid cyst is basically a cyst formed in a pore in between your skin. Hence epidermoid comes from epidermal. They aren't common but are very possible.
the four most common types of cysts are: the Arachnoid Cyst, also called the leptomeningeal cyst the Colloid Cyst the Dermoid Cyst and the Epidermoid cyst, also called the Epidermoid tumor try researching those individualy for further detail. :]

A keratin-filled cyst, also known as an epidermoid cyst, is a non-cancerous growth filled with keratin protein and dead skin cells. It forms when skin cells move deeper into the skin instead of shedding normally, usually due to a blockage of a hair follicle or damage to the skin.
