to covertly grow as a malignant tumour? Body snatcher?

That%26#039;s what a teratoma is...a usually malignant tumor that is derived from misplaced fetal cells that are growing the kinds of tissues their %26quot;instructions%26quot; tell them to. The contents demonstrate that the cells comprising the teratoma were derived from the outermost layer of the developing embryo, the ectoderm. Often they are found either in the gonads or sometimes associated with the pineal gland in the brain.





There is even a condition where it%26#039;s not just a rogue group of cells responsible for a %26quot;fetal%26quot; sort of malignancy...in fact, part or all of another fetus may be found growing or mummified within the body of an individual. There have been cases of this in the literature for many centuries, and they%26#039;ve discussed it on TV in those peculiar sorts of shows they have on Discovery or TLC. The condition is known as fetus in fetu.
Reply:I haven%26#039;t heard the term, but what you are describing has been described as a non-developed parasitig siamese twin.
Reply:I myself have had a dermatoid tumor, i believe they don%26#039;t grow anything. over years you in jest things. swallow a hair or a fingernail, if you are a nail biter. this tumor gets them that way.


that%26#039;s what i was to understand.hope this helps
Reply:Hi, go down to the paragraph I marked with ***** to see their explaination. It basically contains the cells that grow either hair, teeth or nails.





Teratoma


From Wikipedia, the free encyclopedia





A teratoma is a type of tumor that derives from pluripotent germ cells. The word comes from a Greek term meaning roughly %26quot;monster tumor%26quot;. Teratomata usually start from cells in the testes in men, the ovaries in women and in the sacrum in children. The designation teratoma refers to a group of complex tumors having various cellular or organoid components reminiscent of normal derivatives from more than one germ layer. Teratomata are divided into three categories: (1) mature (benign), (2) immature (malignant), and (3) monodermal or highly specialized.





*****Teratomata often contain well-differentiated cells which can result in tissues growing in a teratoma which are quite different from the surrounding tissue—ovarian teratomata have been known to grow hair and teeth. Such a benign cystic teratoma is often termed a dermoid cyst, nowadays more correctly termed a mature teratoma. Some teratomata may contain a mixture of well-differentiated, mature tissues as: respiratory epithelium, hair follicle, fat tissue or mature nervous tissue. Immature teratomata of the ovary have a malignant potential in line with the amount of neuroblastic tissue present.





Testicular teratomata are generally less well-differentiated, and have a worse prognosis (chances of recovery are not as high).





Some teratomata secrete the %26quot;pregnancy hormone%26quot; human chorionic gonadotropin (HCG), which can be used in clinical practice to follow-up successful treatment or relapse in patients with a known HCG-secreting teratoma. It is not recommended as a diagnostic marker.





Some teratomata secrete thyroxine, in some cases to such a degree that it can lead to clinical hyperthyroidism in the patient.





In light of the ethical issues surrounding the source of human stem cells, teratomas are being looked at as an alternative source for research since they lack the potential to grow into functional human beings.
