Fibrosarcoma: From 3 Different Sources

A rare, cancerous tumour of the cells that make up connective tissue.

A fibrosarcoma may develop from a noncancerous fibroma or may be cancerous from the start.

Treatment is by surgical removal and/or radiotherapy.

A cancer of the CONNECTIVE TISSUE arising in the ?broblasts, stem cells that produce connective tissue cells. The tumours can develop in bone or in soft tissue and occur most commonly in the limbs. Treatment is by surgery or RADIOTHERAPY.

n. a malignant tumour of connective tissue, derived from *fibroblasts. Fibrosarcomas may arise in soft tissue or bone; they can affect any organ but are most common in the limbs, particularly the leg. They occur in people of all ages and may be congenital. The cells of these tumours show varying degrees of differentiation; the less well differentiated tumours containing elements of histiocytes have been recently reclassified as malignant fibrous histiocytomas.

Sarcoma

A cancer of connective tissue.

Types are osteosarcoma, Kaposi’s sarcoma, chondrosarcoma, and fibrosarcoma.... sarcoma

Bone Cancer

Malignant growth in bone, which may originate in the bone itself (primary bone cancer) or, more commonly, occur as a result of cancer spreading from elsewhere in the body (secondary, or metatastic, bone cancer). Primary bone cancers are rare. The type that occurs most often is osteosarcoma. Other types include chondrosarcoma and fibrosarcoma. Bone cancer can also start in the bone marrow (see multiple myeloma and leukaemia). The treatment of primary bone cancer depends on the extent to which the disease has spread. If it remains confined to bone, amputation may be recommended; but it may be possible to remove the cancer and fill the defect with a bone graft. Radiotherapy or chemotherapy, or both, may also be needed

The cancers that spread readily to form secondary bone cancer are those of the breast, lung, prostate, thyroid, and kidney.

These bone metastases occur commonly in the spine, pelvis, ribs, and skull.

Pain is usually the main symptom.

Affected bones are abnormally fragile and may easily fracture.

Bone cancer that affects the spine may cause collapse or crushing of vertebrae, damaging the spinal cord and causing weakness or paralysis of one or more limbs.

Secondary bone cancers from the breast and prostate often respond to treatment with hormone antagonists.... bone cancer

Fibrous Dysplasia

a developmental abnormality in which changes occur in bony tissue. Trabecular bone is replaced by fibrous tissue, resulting in aching and a tendency to pathological fracture. In monostotic fibrous dysplasia one bone is affected; polyostotic fibrous dysplasia involves many bones. There is a small risk (5–10%) of malignant transformation (*fibrosarcoma).... fibrous dysplasia

Histiocytoma

n. a tumour that contains *macrophages or *histiocytes, large cells with the ability to engulf foreign matter and bacteria. See also fibrosarcoma.... histiocytoma

Myxosarcoma

n. a *sarcoma containing mucoid material, such as a *liposarcoma or a *fibrosarcoma.... myxosarcoma
