| dermoid cyst of ovary | A common benign cystic teratoma of the ovary, lined for the most part by skin, and containing hair and sebum, but also usually containing a variety of other well differentiated structures within a small inwardly projecting mass of solid tissue. (05 Mar 2000) |
| dermoid cyst of the ovary | Tumours that develop from a totipotential germ cell (a primary oocyte) retained within the ovary. Being totipotential, that cell can give rise to all orders of cells necessary to form mature tissues and often recognizable structures such as hair, bone and sebaceous (oily) material, neural tissue and teeth. Dermoid cysts may occur at any age but the prime age of detection is in the childbearing years. The average age is 30. Up to 15% of women with ovarian teratomas have them in both ovaries. Dermoid cysts can range in size from a centimeter (less than a half inch) up to 45 cm (17 inches) in diameter. They can cause the ovary to twist (torsion) and imperil its blood supply. Although the large majority (about 98%) of ovarian teratomas are benign, the remaining fraction (about 2%) becomes malignant. The larger the dermoid, the greater the risk of rupture with spillage of the greasy contents which can create problems with adhesions, pain etc. Removal is usually the treatment of choice by laparotomy (surgery) or laparoscopy (with a scope). Dermoid cysts of the ovary are also called simply dermoids or ovarian teratomas. (12 Dec 1998) |

| dermoid cyst |
1. an epidermal cyst, usually present at birth, representing a disorder of embryologic development, generally occurring along lines of embryonic fusion, with middorsal, midventral, and branchial cleft locations, most often involving the head, especially around the eyes, and the neck, and lined with stratified squamous epithelium containing cutaneous appendages, including hair. Called also dermoid. 2. ...

| dermoid cyst |
A dermoid cyst, or benign cystic teratoma, also mature cystic teratoma, is a nonmalignant tumor containing a cyst lined by epidermal cells. It can contain all the elements of the dermis, including skin, hair follicles and sweat glands, and the cyst often contains sebum. The lesion may harbor hair and calcified bone or teeth. The calcification will be apparent on x-ray. On gynecologic ultrasonography the sebum appears bright. ...
