  eMedicine - Teratoma, Cystic : Article by Chad A Hamilton, MD
Teratomas, specifically solid teratomas, essentially are devoid of organization; thus, the presence of some degree of organization, a high degree of cellular differentiation, and cystic structure differentiates dermoids from teratomas.
Benign teratomas of the mediastinum are rare, representing 8% of all tumors of this region.

  Teratoma of the Ovary
The MR images of immature teratoma tended to show aqueous fluids and the solid components consisting of numerous cysts with punctate foci of adipose tissue, whereas predominant fluid is sebaceous fluid in the vast majority of mature cystic teratomas.
Teratomas are neoplasms that originate in pluripotential cells and contain representations of all three germ layers in a rather mature state.
The tumor in the fourth case was an immature teratoma with abundant primitive neuroepithelium, and in the fifth case was a mixed germ cell tumor, composed mostly of immature teratoma with a minor component of yolk sac tumor.

 Teratoma - My Child Has - Children's Hospital Boston
A teratoma is generally regarded as a congenital (developing prior to birth) tumor formed by tissue represented by the three layers: ectoderm, entoderm and mesoderm.
Benign teratomas tend to grow aggressively, although they do not spread, while malignant teratomas are characterized by mestastis (spread of a tumor to another part of the body) along with local aggressive growth.
Teratomas in the newborn are often detected on prenatal ultrasound.

Most often found in the ovary or testis, the rare teratoma of the head and neck region arises primarily from Rathke's pouch remnants of the sphenoid bone region, from the lateral neck, and from the tongue.
Many authorities consider this to be a teratoma, going so far as to call such a lesion a teratoid cyst and equating it with the ovarian dermoid cyst.
Treatment of a teratoma consists of conservative surgical removal, a procedure which often requires finesse and delicacy because of the close proximity to important anatomic structures of the head and neck region.

This MRI scan shows a tumor (teratoma) at the base of the spine (seen on the left lower edge of the screen), located in the sacrum and coccyx (sacrococcygeal) area.
A malignant teratoma is a type of cancer consisting of cysts that contain one or more of the three primary embryonic germ layers: ectoderm, mesoderm, and endoderm.
The prognosis for people with malignant teratomas is based on the size of the tumor, its location and the age of the patient.

Gastric teratoma is a very rare tumor, accounting for less than 1% of all teratomas in infants and children.
Although the gastric teratoma is a very rare cause of upper GI bleeding, the diagnosis can be suspected in the presence of a palpable abdominal mass with a differing pattern of calcification in the plain abdominal x-rays.

 Large pre-sacral teratoma in an adult male (a case report). Kripalani AK, Sharma LK J Postgrad Med
[6] The incidence of teratoma amongst presacral tumours is between 9 and 12 per cent,[3] They occur mostly in infants and newborns and only 10 per cent of patients are adults of whom eighty per cent are females.
A teratoma arises from a totepotent cell or cell rests in the embryo and hence is composed of tissue derived from all the three germ layers.
[7] The peculiar location of sacro-coccygeal teratoma has suggested the thesis that the totepotent cells are sequestrated from the vicinity of Hensen's node in the caudal part of the embryo.

 Overview of SCT, Fetal Care Center of Cincinnati
Sacrococcygeal Teratoma / SCT is a tumor made up of tissues from the three primary layers of cells defined in embryos, or germ layers.
Sacrococcygeal Teratoma is detected by ultrasound as a mass on the fetal buttocks associated with a uterus larger than it should be at a specific gestational age.
A fetus with a Sacrococcygeal Teratoma should be followed closely for early signs of hydrops (in utero heart failure), such as ascites, skin orscalp edema or high output cardiac state.

We are dedicated to Sacrococcygeal teratoma research and treatment innovation.
Sacrococcygeal teratoma (SCT) is an unusual tumor that, in the newborn, is located at the base of the tailbone (coccyx).
Babies with small tumors that can be removed along with the coccyx bone after birth can be expected to live normal lives, although they should be followed for development of tumors later in life, using a simple blood test for alpha feto-protein.

The median interval between the diagnosis of ovarian immature teratoma and growing teratoma syndrome was 9 months (range 4-55).
Growing teratoma syndrome was revealed by radiological examinations in nine cases (75%).
Because of the possibility of very late recurrence of growing teratoma syndrome, a prolonged follow-up of patients treated for ovarian immature teratoma is mandatory.

Fetiform teratoma (homunculus) is a term that has been given to a rare form of teratoma that resembles a malformed fetus.
Ovarian teratomas are thought to arise from parthenogenetic development of a primordial germ cell.9 This theory was supported by Linder et al8, who employed cytogenetic and isoenzyme electrophoretic techniques to compare teratomatous and normal tissue.
In summary, we have described a fetiform teratoma, a rare form of a mature cystic teratoma that is highly developed and organized, resembling a fetuslike structure.

 Medical Dictionary: Teratoma - WrongDiagnosis.com
Teratoma: A type of germ cell tumor that may contain several different types of tissue, such as hair, muscle, and bone.
Teratomas occur most often in the ovaries in women, the testicles in men, and the tailbone in children.
Teratoma : true neoplasm composed of a number of different types of tissue, none of which is native to the area in which it occurs; composed of tissues that are derived from three germinal layers, the endoderm, mesoderm, and ectoderm; may be solid or cystic and are classified histologically as mature, immature, and malignant.

 MedlinePlus Medical Encyclopedia: Malignant teratoma
Malignant teratoma is a type of cancer that involves cysts that contain one or more of the three main types of cells found in a developing baby (embryo).
Because malignant teratomas have often spread by the time of diagnosis, anticancer chemotherapy is usually needed.
The prognosis for people with malignant teratomas is based on the size of the tumor, its location, and the age of the patient.

 Characterization of the model for experimental testicular teratoma in 129/SvJ-mice
Four weeks after implantation the embryonic testicular cords had totally disappeared from grafts with teratomas, and the tumour tissue had enlarged the testis and invaded the interstitium of the host testis.
Eleven to 12 weeks after implantation the growth of the teratoma had stopped, and the histology corresponded to that of a mature cystic teratoma.
As conclusions: (1) the metastasizing capacity of the experimental testicular teratoma is very low during 12 weeks, but the behaviour of the tumour in the testicular tissue of the graft is invasive; (2) the growth of experimental testicular teratomas cease 6

 Sacrococcygeal Teratoma - Teratoma Support Foundation - Stories of Loss and Survival
A sacrococcygeal teratoma (SCT) is a tumor that develops at the base of the coccyx (tailbone).
It is seen in 1 in every 35,000 live births, and is the most common tumor in the newborn.
It is vital that the tailbone is removed for sct patients as failure to remove the tailbone is associated with tumour return.

 Sacrococcygeal Teratoma   (Site not responding. Last check: )
This is an example of a sacrococcygeal teratoma [sa-crow-cock-sa-jeal tear-a-toma], which is a tumor that affects roughly one out of every 35,000 births.
The tumor is composed of "germ cells" which are supposed to become part of the reproductive system, but in this case have become tumorous.
Such large teratomas are largely a danger during delivery, or from the blood system of the tumor monopolizing too much of the baby's circulatory system.

Most sacrococcygeal teratomas diagnosed in neonates are not likely to be malignant, and the prognosis tends to be good after resection.
However, prenatally diagnosed sacrococcygeal teratoma associated with fetal hydrops can be rapidly fatal in-utero or can lead to polyhydramnios and premature delivery.
The high-output cardiac failure is related to “vascular steal” from the high blood flow through the tumor.
