A cyst or cavity containing fluid or semi-solid material that develops within or beneath the skin.
From Greek 'derma' (skin) and 'kystis' (bladder or sac). Medical terminology uses '-cyst' for any abnormal sac-like cavity containing material.
A dermatocyst can be anything from a harmless epidermoid cyst to something more serious—doctors use the term to describe the pouch-like structure regardless of what's inside.
