[4 It can form eyes, teeth, hair and even organs as it parasitically feeds on your body for its life. In modern science, we call it by the name teratoma tumor which is Greek for monster and the Latin tumor, from tumere 'to swell' which refers to a mass that grows somewhere in the body.

A teratoma is a type of germ cell tumor which contains several different types of cells, caused when germ cells run amok and start replicating where they shouldn't. This type of tumor is actually present at birth, but it may not be noticed until later in life, and it could be considered a form of congenital birth defect Ovarian teratoma Mature teratoma.

It is also known as the sacrococcygeal teratoma (SCT). It develops in the tailbone section (coccyx) of the human body. The tumor is commonly found in the newborn and the children Ein Teratom, früher auch Wundergeschwulst genannt, ist eine angeborene, oft organähnliche Mischgeschwulst, die sich aus primitiven, pluripotenten Stammzellen entwickelt. Man unterscheidet reife und unreife Formen. Das Teratom ist ein Keimzelltumor, der sich daher in Richtung aller dreier Keimblätter entwickeln kann. Reife Formen können Gewebe wie Haare oder Zähne enthalten, das an der Stelle ihres Auftretens sonst nicht vorkommt und das nicht aus einer Metaplasie hervorgegangen ist.

A grade 1 immature teratoma is made up mostly of non-cancerous tissue, and only a few cancerous areas are seen. These tumors rarely come back after being removed Doctors from all around the world are finding real-life alien type monsters growing within humans. These chimeric creatures have been dubbed teratoma tumors by scientists and they are freaking people out. The word 'teratoma' comes from the Greek word teratos, meaning monster, and tumor, from the Greek tumere - 'to swell. What is Teratoma? The teratoma is a tumor that is encapsulated and has either organ or tissue composition with a complete number of germ layers. There are a few cases wherein the three layers are impossible to identify. It is a congenital defect that has no known cause The most common of these tumors, the mature cystic teratoma (also known as dermoid cyst), typically contains mature tissues of ectodermal (skin, brain), mesodermal (muscle, fat), and endodermal (mucinous or ciliated epithelium) origin

Teratomas are the most common brain tumors Sacrococcygeal teratoma (SCT) is a tumor that develops before birth and grows from a baby's coccyx — more commonly known as the tailbone. It is the most common tumor found in newborns, occurring in 1 out of every 35,000 to 40,000 live births Teratoma with malignant transformation: diverse malignant histologies arising in men with germ cell tumors A variety of nongerm cell histologies, including sarcoma, adenocarcinoma, primitive neuroectodermal tumor and leukemia, may occur in association with germ cell tumor The grade of an immature teratoma refers to the proportion of tissue that contains immature neural elements (which look like fetal organs). For instance, according to the American Cancer Society, a grade 1 immature teratoma consists of mostly noncancerous tissue, and only a few areas of cancerous tissue, which can be seen under the microscope. The stage of an immature teratoma refers to how far it has spread—a stage I tumor means its growth is limited to the ovaries Non-seminomatous histotypes (embryonal carcinoma, choriocarcinoma, yolk sac tumor, teratoma) are less common, more aggressive in behavior, and can be pure or mixed. Testicular teratoma can be found in children and young adults (20 to 35 is the most common age group, as stated previously)

Ovarian teratoma: Also called a dermoid cyst of the ovary, this is a bizarre tumor, usually benign, in the ovary that typically contains a diversity of tissues including hair, teeth, bone, thyroid, etc. A dermoid cyst develops from a totipotential germ cell (a primary oocyte) that is retained within the egg sac (ovary). Being totipotential, that cell can give rise to all orders of cells. Known to medical science as a teratoma (from the Greek for monstrous tumour), news wires quoted Karanam's post-surgical joke that it was her evil twin sister who'd been torturing. Serum CA 19-9 has the highest positivity rate among other tumor markers in ovarian mature cystic teratomas. Elevated serum CA 19-9 levels are correlated with larger tumor size. But the diagnostic value of elevated CA 19-9 in patients with MCT would be poor if the test was used alone Ovarian mature cystic teratomas are common, benign, pelvic tumors that are easily detected by pelvic ultrasonography. However, patients with recurrent teratomas are rarely noted, and cases of bilateral teratomas are even less common. A young woman with a recurrent, right ovarian teratoma had previously undergone surgical removal 2 times. After the second surgery, she underwent regular out.

A teratoma is one type of germ cell tumor. The mediastinum is located inside the front of the chest in the area that separates the lungs Teratoma can be classified into the following types: Sacroccygeal Teratoma. Sacroccygeal Teratoma (SCT) is a type of Teratoma that arises at the base of the tailbone or coccyx. It is found to arise in one out of every 35,000 newborns. It is the most common type of tumor in newborns and is generally non-malignant at the time of birth The tumor was composed of teratoma (cystic areas) and seminoma (solid white areas at the bottom) with minor component of embryonal carcinoma. Interestingly, the teratoma showed pigmented epithelium and membranous structures suggestive of ciliary body of the eye, besides the usual suspects - bone, cartilage, skin, and intestinal glands Sometimes teratoma tumors have a whole array of mature tissue types in them. For instance, when a surgeon or researcher cuts into a teratoma, they may find glands, eye tissue, bone, cartilage and more. A different teratoma from another patient may contain a distinct mix of tissues like digestive glands, skin, sweat glands, and hair Macroscopically, a benign cystic teratoma is often a cystic mass that contains hair, teeth, and skin mixed into thick, sticky, and often foul-smelling material, as seen in the figure. The majority of these tumors are mature and well-differentiated into cystic teratomas. They are not expected to metastasize unless they occur in the testis

Teratoma is a germ cell tumor made of all three germ layers. Because of that teratoma contains tissues and organs which are actually similar, if not the same, to normal tissues and organs. For example, a tumor may contain hair, teeth, bone. In rare cases even more complex organs such as eyes or hands can be found inside the tumor Germ cell tumors (GCT) originate from primordial germ cells and make up 30% of all ovarian tumors.More than 95% of GCT are benign dermoid cysts (mature cystic teratomas).Remaining 5% are malignant. Malignant GCT make up 3% and 20% of all ovarian cancers in Western countries and Asian/African countries respectively Un teratoma maduro é tipicamente benigno e atópase máis habitualmente en mulleres, mentres que un teratoma inmaturo es tipicamente maligno e atópase máis a miúdo en homes. Pénsase que os teratomas xa están presentes no nacemento (conxénitos), pero os de pequeno tamaño non son descubertos ata moito máis tarde na vida do individuo Growing teratoma syndrome is defined as enlarging masses of mature teratoma following chemotherapy for malignant nonseminomatous germ-cell tumors. Typically, there is associated normalization of initially elevated serum tumor markers.
