An epidermal cyst may be caused by:
- Blockage of a hair follicle by skin cells—due to a skin injury
- Damage to a hair follicle due to acne

Problems may be:
- A small, dome-shaped lump beneath the skin
- Foul-smelling, cheese like material that may drain from the cyst
- Redness or pain on or around the cyst
The cyst may go away on its own. It may need to be treated when it causes problems. This can be done with:
- Surgery to remove the entire cyst
- Incision and drainage—to remove the cyst contents, though it may return in time
Antibiotics may be given to treat infection.
