dermoid cyst
1. a tumor of developmental origin consisting of a fibrous wall lined with stratified epithelium and containing hair follicles, sweat glands, sebaceous glands, nerve elements, and teeth; a teratoma. When these cysts occur in the ovary they may present no symptoms, but their long pedicles may cause twisting, resulting in acute abdominal pain. Treatment is surgical removal.
2. a benign teratoma of the ovary, found usually in young women, typically filled with sebaceous material and hair.

dermoid cyst
a tumor of developmental origin consisting of a fibrous wall lined with stratified epithelium and containing hair follicles, sweat glands, sebaceous glands, nerve elements and teeth; a teratoma. Occurs in subcutaneous sites, in the ovary and various locations in the eye, including cornea, conjunctiva and eyelids.
ocular dermoid
dermoid on the eyelid, cornea or conjunctiva.
ovarian dermoid

dermoid sinus
an inherited abnormality in Rhodesian Ridgeback dogs in which a neural tube, which is an invagination of the skin, connects the skin with the dura mater in the vertebral canal or to an intervening structure. Characterized by the presence of a tuft of hair protruding from each sinus and sometimes complicated by infection with drainage.

A subsequent MRI scan showed additional imaging features characteristic of a ruptured dermoid cystic tumor (Figure 2).
While a two-year lapse in gynecological visits could be enough time to allow a fibroid to grow large enough to require surgery, it is highly unusual for doctors to discover dermoid cysts on a woman's ovaries amid surgery - and then have them so entangled that the ovary must be removed, they said.
