fibrosarcoma

 [fi″bro-sahr-ko´mah]
a sarcoma arising from collagen-producing fibroblasts.

fi·bro·sar·co·ma

(fī'brō-sar-kō'mă),
A malignant neoplasm derived from deep fibrous tissue, characterized by bundles of immature proliferating fibroblasts arranged in a distinctive herringbone pattern with variable collagen formation, which tends to invade locally and metastasize by the bloodstream.

ameloblastic fibrosarcoma  an odontogenic tumor that is the malignant counterpart to an ameloblastic fibroma, within which it usually arises.

fibrosarcoma

An uncommon malignant tumour of the cells that form fibrous tissue (fibroblasts). These cells are found in all parts of the body, and the tumour may affect almost any tissue, including bone, but is commonest in the leg or buttock. Radical surgery is necessary.
