- From Wikipedia, the free encyclopedia. A teratoma is a tumor with tissue or organ components resembling normal derivatives of more than one germ layer. Although the teratoma may be monodermal or polydermal (originating from one or more germ layers), its cells may differentiate in ways suggesting other germ layers.sually, a teratoma will contain no organs but rather one or more tissues normally found in organs such as the brain, thyroid, liver, and lung.

teratology Toxic chemicals used in agriculture are tested as well. Teratology is also of importance in the biology of development, since knowledge of the deviations caused by teratogens or mutant genes is a means of discovering the motivating forces and controlling mechanisms of normal embryonic development in animals and man.

- Teratogens are substances or other factors that can cause congenital abnormalities, which are also called birth defects. Usually these abnormalities arise in the third to eighth weeks of pregnancy, when the major organ systems are forming. Examples of teratogens include certain chemicals, medications, and infections or other diseases in the mother.

Sacrococcygeal teratoma (SCT) Sacrococcygeal (sae-crow-cox-i-gee-ul) teratoma (terr-uh-tome-uh) is the most common tumor found in newborns. Sacro refers to sacrum and coccy refers to coccyx. The sacrum is a curved triangular bone at the bottom end of the backbones, just before the coccyx. The coccyx is the last bone of the vertebral column.

Hematoma Hematoma is generally defined as a collection of blood outside of blood vessels. Most commonly, hematomas are caused by an injury to the wall of a blood vessel, prompting blood to seep out of the blood vessel into the surrounding tissues.A hematoma can result from an injury to any type of blood vessel (artery, vein, or small capillary).ometimes hematomas are named based on their location. Some examples include: 1  Subdural hematoma: a hematoma between the brain tissue and the inside lining of the brain. 2  Spinal epidural hematoma: a hematoma between spinal vertebrae and the outside lining of the spinal cord.

subdural hematoma A subdural hematoma is a collection of blood in the space between the outer layer (dura) and middle layers of the covering of the brain (the meninges). It is most often caused by torn, bleeding veins on the inside of the dura as a result of a blow to the head. subdural hematoma is caused by an injury to the head that tears blood vessels. In childhood, hematomas are a common complication of falls. A subdural hematoma also may be an indication of child abuse, as evidenced by shaken baby syndrome.

- A teratoma is present at birth, but may not be noticed until later in life. Ultrasounds may be useful in detecting teratomas. Chemotherapy and radiation treatment may cause hair loss in some patients. Chemotherapy may be used to prevent the recurrence of teratomas that have been removed.

- Teratozoospermia, also known as teratospermia, is a semen alteration in which there is a large number of spermatozoa with abnormal morphology. It is a sperm condition that may lead to serious consequences, such as male infertility. The sperm parameter that is compromised is sperm morphology. The World Health Organisation (WHO) offers guidelines to evaluate semen parameters (some examples of these parameters are concentration, motility, or morphology).

Teratology As early as the 17th century, teratology referred to a discourse on prodigies and marvels of anything so extraordinary as to seem abnormal. In the 19th century, it acquired a meaning more closely related to biological deformities, mostly in the field of botany.
