Signs and Symptoms
Pilar cysts are usually found on the scalp. They appear as smooth, movable bumps under the skin. There is often more than one in an area, and they may become quite large. Occasionally, they are tender to the touch.

The cysts may spontaneously burst open (rupture), usually causing intense redness and irritation.
