Epidermoid cysts are generally non-serious skin cysts.[3] They typically do not result in pain, unless an abscess forms or they rupture internally.[2] A dark pore may be present.[3] They are most common on the face, neck, and trunk; though may form anywhere.[3] They often gradually grow over years.[3] Rare complications may include cancer.[3]
Generally they occur randomly; though are associated with Gardner syndrome, Gorlin syndrome, and the medication cyclosporine.[3] They occur under the epidermis and are filled with keratin.[3] Diagnosis is generally based on symptoms and examination.[1]
Specific treatment is not required in those without symptoms.[1] Larger cysts may be removed surgically, with efforts to also remove the capsule.[1] If infected, incision and drainage together with antibiotics may be indicated.[1]
They are the most common type of cyst.[3] Most often they occur in peoples 30s and 40s.[3] They effect males twice as often as females.[3] They have incorrectly been referred to as a "sebaceous cyst", as they do not contain sebum.[1]
