User:Mr. Ibrahem/Epidermoid cyst

Epidermoid cysts are generally non-serious skin cysts. They typically do not result in pain, unless an abscess forms or they rupture internally. A dark pore may be present. They are most common on the face, neck, and trunk; though may form anywhere. They often gradually grow over years. Rare complications may include cancer.

Generally they occur randomly; though are associated with Gardner syndrome, Gorlin syndrome, and the medication cyclosporine. They occur under the epidermis and are filled with keratin. Diagnosis is generally based on symptoms and examination.

Specific treatment is not required in those without symptoms. Larger cysts may be removed surgically, with efforts to also remove the capsule. If infected, incision and drainage together with antibiotics may be indicated.

They are the most common type of cyst. Most often they occur in peoples 30s and 40s. They effect males twice as often as females. They have incorrectly been referred to as a "sebaceous cyst", as they do not contain sebum.
