Ovarian teratoma
Summary cause disease clinical pathology laboratory diagnosis and differential treatment to prevent complications prognosis
In all types of ovarian tumors, there is a tumor contains hair, teeth, bones and grease, which we call ovarian teratoma.
Ovarian teratoma ovarian germ cell tumor is in a common, it is not a monster after the Wye women evolved from, but from germ cell dysplasia in those belonging to a growth in ovarian tissue from the abnormal reproductive cells hyperplasia, a gathering of the tumor. Because of the presence of germ cells from human embryonic leaves, mesodermal and organizations within the embryo of the three components, so there will be yard of hair, grease, skin, teeth, bone such as the embryo leaf tissue, which may contain or mesodermal endodermal leaf tissue such as muscle, gastrointestinal tract, thyroid, and so on.
Ovarian cancer teratogenic there are different types, including mature and immature cancer abnormal served slightly shares aneurysm. 97 per cent of mature cystic teratoma, called dermoid cyst. Dermoid cyst is the most common type of ovarian tumors of all of the 10% -20% of germ cell tumors of 85% -97%. Because it has nothing to do with pregnancy, ovarian teratoma can occur at any age, newborns, young people, middle-aged or elderly breast cancer can be, but 80% -90% for 20 to 40-year-old female reproductive period, in patients with ovarian tumors about 1 / 4-1/3.
Mature ovarian cystic teratoma is generally medium-sized side for more than 12 per cent of bilateral, the appearance of a circular or oval-shaped, coated in a layer of smooth contained, the wall of tough, mostly single-room, Cavities are the most common in the Mission and the hair grease, often teeth and bone. Differentiation and maturation of these organizations, most of benign tumor, about 2% of malignant transformation.
A very small number of immature teratoma, are malignant, they malignant germ cell tumors, with the potential of recurrence and metastasis. For the solid tumor, which may have cystic region. Unlike the Organization of the normal tissue, cell differentiation bad, transfer, erosion, planting characteristics. The disease occurs in young people and children.
Generally speaking the prognosis immature teratoma less effective, surgery can not guarantee completely, and efficiently eliminate, the risk of recurrence. The teratoma better the prognosis, the possibility of malignant transformation of benign only 2% to 3%, does not affect ovarian function, normal menstrual after surgery, the pregnancy rate of normal, and there is no compound the problem.
