A typically benign ovarian cyst, consisting primarily of fat but may also contain bone, teeth, thyroid and hair ranging in size from 1/2 inch to 17 inches in diameter. Dermoid cysts can cause twisting (torsion) of the ovary endangering blood supply. Often diagnosed by MRI and removed by laparotomy.
A cyst which contains skin tissue. May be congenital or acquired.
Benign ovarian cyst, consisting predominantly of fat. May also contain bone, teeth, thyroid and hair. Ovary containing dermoid cyst is at increased risk of twisting (torsion). Often removed by laparotomy with ovarian reconstruction. An MRI is usually useful in making pre-operative diagnosis.
a cystic tumor (usually benign) with an epithelium-lined wall and a cavity containing other material
a congenital defect (present from birth) that occurs during embryonic development when the skin layers do not properly grow together
a consequence of a developmental abnormality where fragments of ectoderm are left behind at the lines of embyrological skin fusion
a noncancerous tumor about the size of a pea that is usually present since birth
a non-malignant cyst that
a pocket or cavity under the skin that contains
a saclike growth, present at birth, that contains hair, fluid, teeth,
a saclike growth that is present at birth
a very unusual type of cyst, that develops from the same type of cell that the egg is made of
(See benign cystic teratoma).
A tumor consisting of displaced ectodermal structures along the lines of embryonic fusion, the wall being formed of epithelium-lined connective tissue, including skin appendages, and containing keratin, sebum, and hair. (Stedman, 25th ed)
A cyst of the midline of the upper neck or the anterior floor of the mouth of young patients, derived from remnants of embryonic skin, consisting of a lumen lined by a keratinizing stratified squamous epithelium and containing one or more skin appendages such as hair, sweat, or sebaceous glands.
a benign tumor made up of hairs, sweat glands, and sebaceous glands.
A dermoid cyst is a teratoma that contains developmentally mature skin, with hair follicles and sweat glands, sometimes luxuriant clumps of long hair, and often pockets of sebum, blood, or fat. Because it contains mature tissue, a dermoid cyst almost always is benign. The rare malignant dermoid cyst usually develops squamous cell carcinoma.
