Epidermal inclusion cyst (EIC), also known as sebaceous cyst and epidermoid cyst, is the most common cyst of the skin. It ranges in size from a few millimeters to a few centimeters and originates from the follicular infundibulum. Its contents are a cheesy, malodorous mixture of degraded lipid and keratin. It often ruptures, with associated pain and inflammation.
