ovarian teratoma
An ovarian tumor that is usu-
ally benign and typically contains a diversity of
tissues. An ovarian teratoma develops from a totipo-
tential germ cell—a primary oocyte—that is
retained within the ovary. Totipotential cells can give
rise to all orders of cells that are necessary to form
mature tissues and often recognizable structures,
such as hair, bone, and sebaceous (oily) material,
neural tissue, and teeth. Any of these tissues may be
found in an ovarian teratoma. Such cysts may occur
at any age, but the prime age of detection is in the
childbearing years. Treatment involves surgical
removal, which can be done via laparotomy (open
surgery) or laparoscopy (with a scope). Also
known as dermoid cyst of the ovary or simply der-
moid. See also 
cyst, ovarian; parthenogenesis.
ovary
The female gonad, one of a pair of repro-
ductive glands in women. The ovaries are located in
the pelvis, one on each side of the uterus. Each ovary
is about the size and shape of an almond. The
ovaries produce eggs (ova) and female hormones.
During each monthly menstrual cycle, an egg is
released from one ovary. The egg travels from the
ovary through a fallopian tube to the uterus. The
ovaries are the main source of female hormones,
which control the development of female body char-
acteristics, such as the breasts, body shape, and
body hair. They also regulate the menstrual cycle and
pregnancy.
