| histiocytoma, fibrous | A tumour composed, wholly or in part, of cells with the morphologic characteristics of histiocytes and with various fibroblastic components. There are many variants and many names. Superficially located histiocytic lesions behave benignly but deep, benign histiocytomas may invade locally into surrounding tissue. Fibrous histiocytomas can occur anywhere in the body. Superficial lesions are always cured by simple excision; a wider margin of tissue should be obtained for deep, benign types. Local recurrence is uncommon. (12 Dec 1998) |
| solitary fibrous tumour | A benign tumour of fibrous tissue which usually arises in the pleural space on other sites. Synonym: benign mesothelioma. (05 Mar 2000) |
| neoplasms, fibrous tissue | Neoplasms composed of fibrous tissue, the ordinary connective tissue of the body, made up largely of yellow or white fibres. The concept does not refer to neoplasms located in fibrous tissue. (12 Dec 1998) |
| idiopathic fibrous hyperplasia | A condition of cystic bone growth that results from abnormal bone development. May occur with bone lesions, skin pigmentation and endocrine abnormalities. See: McCune-Albright syndrome. Origin: Gr. Plassein = to form (27 Sep 1997) |
| idiopathic fibrous mediastinitis | <radiology> Histoplasmosis most common cause, can cause superior vena cava obstruction (12 Dec 1998) |
