Milium (dermatology)

"Milia" redirects here. For other uses, see Milia (disambiguation).

A milium (pl.: milia), also called a milk spot or an oil seed,^[1] is a clog of the eccrine sweat gland. It is a keratin-filled cyst that may appear just under the epidermis or on the roof of the mouth.^[2][3] Milia are commonly associated with newborn babies, but may appear on people of any age.^[4] They are usually found around the nose and eyes, and sometimes on the genitalia, often mistaken by those affected as warts or other sexually transmitted diseases. Milia can also be confused with stubborn whiteheads.

Relative incidence of cutaneous cysts. Milia is labeled at bottom right.

In children, milia often disappear within two to four weeks. For adults, they may be removed by a physician (a dermatologist has specialist knowledge in this area). A common method that a dermatologist uses to remove a milium is to nick the skin with a #11 surgical blade and then use a comedone extractor to press the cyst out.^[5]
