Teratoma tumor

A teratoma is a rare type of tumor that can contain fully developed tissues and organs, including hair, teeth, muscle, and bone. Teratomas are most common in the tailbone, ovaries, and testicles,.. A teratoma is a type of germ cell tumor that is believed to be present at birth. These are well-encapsulated tumors that can contain tissue normally found in the brain, liver or lungs. In some cases there have been reports of hair, teeth and bones appearing in teratoma. Teratoma may be classified as mature or immature Teratoma is a type of germ cell tumor that may contain several different types of tissue, such as hair, muscle, and bone. Teratomas may be mature or immature, based on how normal the cells look under a microscope. Sometimes teratomas are a mix of mature and immature cells

Teratoma: Definition, Symptoms, Causes, Cancer, Treatment

The tailbone teratoma is the most common among the rare form of a tumor. 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. But, the rare form of tumor develops in one among several thousand (35000 to 40000) infants 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. As you can see for yourself, these tumors look like the scariest fricken monsters that I have ever seen and they are growing in people 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 Teratom je nádor složený z různých tkání, které v daném místě normálně nebývají a které vznikly z embryonální tkáně. Často bývá v pohlavních žlázách. Má různý stupeň zralosti a podle toho i stupeň zhoubnosti teratokarcinom.Teratomy mají obvykle podobu vaku různé velikosti, které v sobě obsahují známé tkáně či orgány např. zuby, vlasy, kost, vzácně.

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 necessary to form mature tissues and often recognizable structures such as hair, bone and sebaceous (oily. Teratoma is a rare type of tumor, which can contain fully developed tissues and organs such as hair, teeth, muscle or even bones inside. Although teratomas develop in any part of the body, they are more frequent in the tailbone or coccyx (the final segment of the spine), ovaries and testicles for males

Teratoma - Germ Cell Tumor Symptoms, Diagnosis, Treatment

Teratoma is the most common mediastinal germ cell tumor, composed of tissues from more than one of the three primitive germ cell layers (teeth, skin, and hair from ectoderm; cartilage and bone from mesoderm; and bronchial, intestinal, or pancreatic tissue from endoderm). Most teratomas are well differentiated and benign (mature), but rarely. Mediastinal teratomas are germ cell tumors arising from ectopic pluripotent stem cells that failed to migrate from yolk endoderm to the gonad. By definition, they should contain elements from all three embryological layers: endoderm, mesoderm and ectoderm. Frequently, however, elements from only two layers are evident 7 (see teratoma article)

A teratoma is a tumor of germ cell origin, containing tissues from more than one germ cell line, It can be ovarian or testicular in its origin. [4] and are almost always benign. [5] An immature teratoma is thus a very rare tumor, representing 1% of all teratomas , 1% of all ovarian cancers , and 35.6% of malignant ovarian germ cell tumors . [6 A teratoma is a type of cancer that contains one or more of the three layers of cells found in a developing baby (embryo). These cells are called germ cells. 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 By definition, the term teratoma can be used only when tumor elements derive from two or three germ layers. These tumors are usually well circumscribed, round or lobulated, and multicystic and compress the surrounding structures. The cystic component of the tumor may be watery, mucoid, or sebaceous A Teratoma of Lung is the most common type of germ cell tumor of the lung. However, the lung is a very uncommon site for such a tumor, and hence, the origin of the teratoma from other common sites (such as gonads) should be eliminated prior to establishing a diagnosis of primary Teratoma of Lung A sacrococcygeal teratoma (SCT) is a tumor located at the base of the spine, often called the 'tail bone' in the area just above the buttocks. This kind of tumor is made up of different cells found during very early development. The tumor usually has both solid and cystic (fluid-filled) parts. Tumors with a greater cystic (fluid-filled) component may grow more slowly tha

Geographically, the testicular cancer tumour is found worldwide but with highest incidence in developed countries Intracranial teratomas are uncommon intracranial neoplasms, which can have a bewildering variety of components and thus a wide range of appearances.They can be divided into two broad categories, intra-and extra-axial, which differ in epidemiology and clinical presentation. Another method of classifying an intracranial teratoma is as mature, immature and mature with malignant transformation Growing teratoma syndrome: immature teratoma status post neoadjuvant chemotherapy and consists of persistence or enlargement of ovarian tumor with normalization of serum markers Thought to represent conversion of deposits of immature teratoma into mature teratoma as a result of chemotherapy (chemotherapeutic retroconversion) ( Int J Gynecol. Conclusions: Teratoma of the head and neck, though rare, is an important part of the differential diagnosis of neck masses in children, particularly in the perinatal period. The ability to make this diagnosis prenatally with high-resolution fetal ultrasound and MRI (magnetic resonance imaging) permits planning for airway and tumor management.

It is seen in 1 in every 35,000 live births, and is the most common tumor in the newborn. These are usually non-malignant at birth If more than 50 percent of the tumor is comprised of well-differentiated elements, then the tumor is referred to as a mature teratoma. The most frequent site of teratomas is the gonads followed by the mediastinum [1, 2]. Ninety percent of the cardiac teratomas have been found in the pericardium and the rest in the myocardium

It is the most common tumor found in newborns, occurring in 1 out of every 35,000 to 40,000 live births In adults, a diagnosis of sacrococcygeal teratoma may be suspected during a routine pelvic or rectal examination that detects the presence of a mass or tumor. A diagnosis of sacrococcygeal teratoma may be confirmed by surgical removal and microscopic examination of affected tissue (biopsy) A teratoma is a congenital (present prior to birth) tumor formed by different types of tissue. Teratomas in newborns are generally benign and don't spread.

Teratoma vs Seminoma . Both teratoma and seminoma are germ cell tumors, which share some of the similar characteristics, but they do differ in many ways. Teratoma is a well-encapsulated tumor having components derived from all three germ layers, but seminoma arises from the germ cell epithelium of the seminiferous tubules NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine A teratoma is a type of tumour that arises from stem cells. Stem cells are the 'blank' cells that can turn into any type of specialised tissue within the body. This means that teratoma tumours can be made up of any type of specialised tissue from anywhere on the body, such as skin, hair and teeth
