Cartilage tumor

Last updated

Cartilage tumors, also known as chondrogenic tumors, are a type of bone tumor that develop in cartilage, and are divided into non-cancerous, cancerous and intermediate locally aggressive types. [1] [2] [3]

A brain tumor occurs when abnormal cells form within the brain. There are two main types of tumors: malignant (cancerous) tumors and benign (non-cancerous) tumors. These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors. All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved. Where symptoms exist, they may include headaches, seizures, problems with vision, vomiting and mental changes. Other symptoms may include difficulty walking, speaking, with sensations, or unconsciousness.

<span class="mw-page-title-main">Bone tumor</span> Abnormal growth of tissue within bone

A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. There may be a lump, pain, or neurological signs from pressure. A bone tumor might present with a pathologic fracture. Other symptoms may include fatigue, fever, weight loss, anemia and nausea. Sometimes there are no symptoms and the tumour is found when investigating another problem.

<span class="mw-page-title-main">Osteosarcoma</span> Cancerous tumour in a bone

An osteosarcoma (OS) or osteogenic sarcoma (OGS) is a cancerous tumor in a bone. Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin and that exhibits osteoblastic differentiation and produces malignant osteoid.

Malignancy is the tendency of a medical condition to become progressively worse; the term is most familiar as a characterization of cancer.

<span class="mw-page-title-main">Chondrosarcoma</span> Malignant tumor originating in cartilage

Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas. About 30% of bone sarcomas are chondrosarcomas. It is resistant to chemotherapy and radiotherapy. Unlike other primary bone sarcomas that mainly affect children and adolescents, a chondrosarcoma can present at any age. It more often affects the axial skeleton than the appendicular skeleton.

The perichondrium is a layer of dense irregular connective tissue that surrounds the cartilage of developing bone. It consists of two separate layers: an outer fibrous layer and inner chondrogenic layer. The fibrous layer contains fibroblasts, which produce collagenous fibres. The chondrogenic layer remains undifferentiated and can form chondroblasts. Perichondrium can be found around the perimeter of elastic cartilage and hyaline cartilage.

<span class="mw-page-title-main">Chondrocyte</span> Cell that makes up cartilage

Chondrocytes are the only cells found in healthy cartilage. They produce and maintain the cartilaginous matrix, which consists mainly of collagen and proteoglycans. Although the word chondroblast is commonly used to describe an immature chondrocyte, the term is imprecise, since the progenitor of chondrocytes can differentiate into various cell types, including osteoblasts.

<span class="mw-page-title-main">Benign tumor</span> Mass of cells which cannot spread throughout the body

A benign tumor is a mass of cells (tumor) that does not invade neighboring tissue or metastasize. Compared to malignant (cancerous) tumors, benign tumors generally have a slower growth rate. Benign tumors have relatively well differentiated cells. They are often surrounded by an outer surface or stay contained within the epithelium. Common examples of benign tumors include moles and uterine fibroids.

<span class="mw-page-title-main">Enchondroma</span> Benign bone tumor composed of cartilage

Enchondroma is a type of benign bone tumor belonging to the group of cartilage tumors. There may be no symptoms, or it may present typically in the short tubular bones of the hands with a swelling, pain or pathological fracture.

<span class="mw-page-title-main">Giant-cell tumor of bone</span> Bone tumor composed of agglomerated osteoclast-like cells

Giant-cell tumor of the bone (GCTOB), is a relatively uncommon bone tumor. It is characterized by the presence of multinucleated giant cells. Malignancy in giant-cell tumor is uncommon and occurs in about 2% of all cases. However, if malignant degeneration does occur, it is likely to metastasize to the lungs. Giant-cell tumors are normally benign, with unpredictable behavior.

<span class="mw-page-title-main">Chondroblast</span> Mesenchymal progenitor cell that forms a chondrocyte

Chondroblasts, or perichondrial cells, is the name given to mesenchymal progenitor cells in situ which, from endochondral ossification, will form chondrocytes in the growing cartilage matrix. Another name for them is subchondral cortico-spongious progenitors. They have euchromatic nuclei and stain by basic dyes.

<span class="mw-page-title-main">Subungual exostosis</span> Medical condition

Subungual exostosis is a type of non-cancerous bone tumor of the chondrogenic type, and consists of bone and cartilage. It usually projects from the upper surface of the big toe underlying the nailbed, giving rise to a painful swelling that destroys the nail. Subsequent ulceration and infection may occur.

<span class="mw-page-title-main">Aneurysmal bone cyst</span> Benign bone tumor consisting of blood

Aneurysmal bone cyst (ABC) is a non-cancerous bone tumor composed of multiple varying sizes of spaces in a bone which are filled with blood. The term is a misnomer, as the lesion is neither an aneurysm nor a cyst. It generally presents with pain and swelling in the affected bone. Pressure on neighbouring tissues may cause compression effects such as neurological symptoms.

<span class="mw-page-title-main">Adamantinoma</span> Medical condition

Adamantinoma is a rare bone cancer, making up less than 1% of all bone cancers. It almost always occurs in the bones of the lower leg and involves both epithelial and osteofibrous tissue.

<span class="mw-page-title-main">Salivary gland tumour</span> Medical condition

Salivary gland tumours, also known as mucous gland adenomas or neoplasms, are tumours that form in the tissues of salivary glands. The salivary glands are classified as major or minor. The major salivary glands consist of the parotid, submandibular, and sublingual glands. The minor salivary glands consist of 800 to 1000 small mucus-secreting glands located throughout the lining of the oral cavity. Patients with these types of tumours may be asymptomatic.

A mixed tumor is a tumor that derives from multiple tissue types. A biplastic tumor or biphasic tumor has two tissue types.

Bizarre parosteal osteochondromatous proliferation (BPOP), also known as Nora's lesion, is a type of non-cancerous bone tumor belonging to the group of cartilage tumors.

<i>WHO Blue Books</i> Series of books that classify tumours

The WHO Classification of Tumours, more commonly known as the WHO Blue Books, is a series of books that classify tumours. They are compiled by expert consensus and published by the World Health Organization's (WHO) International Agency for Research on Cancer (IARC). They appear in print and online in a series of 15 books, each of which focuses on a major tumour group and defines the cause, mechanism, signs and symptoms, basic structure, diagnosis, epidemiology and outcomes of up to 300 types of tumours.
