Epidermoid cysts can be located almost anywhere but are most common on the face, neck, scalp, or trunk.
A cyst appears as a dome-shaped, skin-colored growth that usually moves when touched and pressed upon. It may have a small opening in the center.
The cyst can be well-defined or irregular due to prior rupture, scarring, and regrowth.
If manipulated or infected, the cyst can become red and may be tender.
