Chondrosarcoma
|
|
ChondrosarcomaA malignant tumor that forms in cartilage cells (chondroplasts) and that produces cartilage matrix. Chondrosarcoma can be primary or secondary. Primary chondrosarcoma forms in bone and is found in children. Secondary chondrosarcoma arises from preexisting benign defects of cartilage (such as an osteochondroma or enchondroma), usually after age 40. Treatment is mainly by surgery.
RELATED TERMS--------------------------------------
Malignant
Cancerous; life-threatening.
Tumor
Overgrowth of tissue.
Cartilage
A firm, flexible connective tissue. In vertebrates, the cartilage forms the skeleton in the early stages of development, after which it is largely replaced by bone. Some cartilage remains at the joints to give flexibility and support.

Bone
Bone refers either to a hardened connective tissue or to one of the individual structures, or organs, into which it is formed, found in many animals. Bones support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; are also involved with cell formation, calcium metabolism, and mineral storage. The bones of an animal are, collectively, known as the skeleton.
Benign
Non-malignant; not life-threatening.
Osteochondroma
A benign cartilage-tipped exostosis.
Surgery
Treating diseases or other medical conditions by operating on a patient to remove or repair parts of the body.
SIMILAR TERMS--------------------------------------
Chondritis
Inflammation of the cartilage.
Chondrocalcinosis
Calcification of articular cartilage. May be associated with attacks of joint inflammation that may mimic gout ('Pseudogout').
Chondrodysplasia
Congenital condition in which there is a mutation of a collagen-associated gene.
Chondroitin sulfate
A glycosaminoglycan (formerly called a mucopolysaccharide) found in cartilage, bone, blood vessels and connective tissues. There are two forms: chondroitin sulfate A and chondroitin sulfate C. One or both types accumulate abnormally in several of the mucopolysaccharidosis disorders. Chondroitin sulfate B is now called dermatan sulfate.
Chondromalacia
Softening of cartilage.
Chondromalacia patellae
A condition in which knee pain results from wear of the cartilage at the back of the kneecap (patella).
Chondroplasia
The formation of cartilage by specialized cells called chondrocytes.
PREVIOUS AND NEXT TERMS--------------------------------------
Cholesterol ester transfer protein
A protein that helps regulate the size of cholesterol particles and influence the process of atherogenesis (the formation of plaques in arteries). Abbreviated CETP. The CETP gene is in chromosome band 16q21. A number of mutations are known in the CETP gene. Some result in CEPT deficiency, increased levels of HDL ("good") cholesterol and unusually large cholesterol particles. CETP deficiency appears to be a good mutation which is antiatherogenic and may confer unusual longevity to the person. Also called cholesteryl ester transfer protein.
Cholesterol guidelines
The guidelines on cholesterol for adults.
Cholestin
One of the three major preparations of red yeast rice, a tradition Chinese medicine now used to lower cholesterol. Cholestin is also known as Hypocol.
Chondroitin sulfate
A glycosaminoglycan (formerly called a mucopolysaccharide) found in cartilage, bone, blood vessels and connective tissues. There are two forms: chondroitin sulfate A and chondroitin sulfate C. One or both types accumulate abnormally in several of the mucopolysaccharidosis disorders. Chondroitin sulfate B is now called dermatan sulfate.
Chondroplasia
The formation of cartilage by specialized cells called chondrocytes.
Chondrosarcoma
Chorda tympani
A branch of the facial nerve (the seventh cranial nerve) that serves the taste buds in the front of the tongue, runs through the middle ear, and carries taste messages to the brain.
Chordae tendineae
Thread-like bands of fibrous tissue which attach on one end to the edges of the tricuspid and mitral valves of the heart and on the other end to the papillary muscles, small muscles within the heart that serve to anchor the valves.
Chordoma
A form of bone cancer that usually starts in the lower spinal column.
Chorioangioma, placental
A benign vascular (blood vessel) tumor of the placenta (afterbirth). Large chorioangiomas cause complications including polyhydramnios (excess amniotic fluid), maternal and fetal clotting problems (coagulopathies), premature delivery, toxemia, fetal heart failure, and hydrops (excess fluid) affecting the fetus.
Choriocarcinoma
A highly malignant tumor that arises from trophoblastic cells within the uterus. Choriocarcinoma tends to be invasive and to metastasize early and widely through both the venous and lymphatic systems. Choriocarcinoma is one of the two types of gestational trophoblastic tumor, the other being hydatidiform mole.
