Legend
vagus may be the development of embryonic tissue formed in the lung tumors, mostly benign tumor may contain tissues from three germ layers, such as hair, muscle, cartilage and glands, epithelial and so on.

diagnosis of teratoma is what causes it? (A) etiology (b) harm to the pathogenesis of teratoma diagnosis of an ovarian teratoma. History, symptoms: age of onset mostly in young adults, men and women without discrimination. Early symptoms, larger tumor or infection,
skechers women, may have cough, sputum Cameroon, breathing difficulties and even hemoptysis and other symptoms may be recurrent, a small number of clubbing. II. Medical examination found that: Early symptoms, those huge tumor, lung auscultation breath sounds may have weakened the local, after the lung infection can have moist rales. III. Laboratory examinations: X-ray shows a round, oval, solid or cystic sizes shadow capsule uneven density, and often can be found in the teeth or calcification, chest CT scan can help to more clearly show the structure confirmed intracapsular . Necessary, feasible transthoracic lung biopsy or thoracotomy confirmed. IV. Differential diagnosis: should work with lung cancer, other pulmonary benign phase identification. Treatment measures】 【asymptomatic without treatment, antibiotic therapy when infection, tumor giant severe symptoms of oppression can be surgically removed. Teratoma is what causes? (A) of the pathogenesis of atopic spinal tumor, Department of embryonic tissue during embryonic development of the residual cell development from mesoderm. According to the organizational structure can be divided into epidermoid cyst, dermoid cysts, teratoid cyst and teratoma. The first two are made of tissue from the ectoderm. Teratoma with three germ layers, teratoid cysts containing two embryos layer structure. (B) the pathogenesis of spinal teratoma is derived from three embryonic cell layers of the mixture. According to histological features, can be divided into a mature teratoma, immature and malignant teratoma three types. The origin of intraspinal teratoma remaining controversial. Poeze so that the spinal teratoma formation may have originated in the early embryo, immature germ cells of dislocation, the spinal cord central canal ependymal diverticulum formation or abnormal embryonic development mechanism. Some patients can teratoma clusters occurring at the skin site adjacent to plexiform growth of hair, or associated with spina bifida, the most likely way for the performance of the early formation of immature embryonic germ cells caused by dislocation. Harm a teratoma, ovarian germ cell tumor is a common one, because the germ cells in the human body contains ectodermal, mesoderm and endoderm leaves three organizational components, so the tumor will house hair, grease, skin , teeth, bone slices loaded with embryo leaf tissue, may also contain mesoderm or endoderm tissue like muscle, gastrointestinal, thyroid,
skechers outlet, etc., can be like a 2, mediastinal teratomas can often caused by compression of respiratory cough, breathing difficulty and jugular vein engorgement doctor; more retroperitoneal teratoma with abdominal pain, and can lead to intestinal obstruction. Sacrococcygeal teratoma and more pelvic and invisible because of constipation, difficulty in defecation and considerate, urinary retention and treatment. 3, and the experience of co-infection aneurysm rupture, as is the abnormal tissue, for a long time the possibility of malignancy in the body there. 4 malignant and benign tumor of the points, usually manifested rapid tumor growth, lose their elasticity, exogenous tumor visible superficial vein engorgement, congestion, local infiltration of skin and with skin temperature increased. Concurrent weight loss, anemia, fever and other systemic tumors reported symptoms. Ovarian teratoma ovarian teratomas are common ovarian germ cell tumors, abnormal proliferation of germ cells from the formation of agglomeration,
skechers shape up shoes, can occur in the testis, ovary, mediastinum,
skechers shape ups, sacrococcygeal, etc., tumor Central Standing Committee has hair, teeth, muscle, fat,
shape ups skechers, etc. leaf tissue of human embryos. include the type of ovarian teratoma and immature teratoma mature teratoma, immature teratoma generally poor prognosis, surgery can not guarantee complete removal,
shape up skechers, and there is the risk of relapse. The better prognosis of benign teratomas, tumor differentiation, maturation, about 2% of the malignant transformation. clinically benign and malignant teratoma can determine the B-, CT, MRI or pathological examination. according to the report you provide ultrasound , should belong to the virtuous, but need to go to big hospitals for further diagnosis, it is recommended to do it again checks to determine the nature of mass. surgical options could be considered minimally invasive laparoscopic surgery and quick recovery. benign ovarian teratoma does not have to ovariectomy , viable part of local remove or oophorectomy patients, malignant will have under the circumstances to determine the scope of operation. generally normal after menstruation, does not affect the ovaries and reproductive functions, but usually does not reduce pregnancy rates. term Atlas more Multi Atlas Open Category: Medicine
