fibroma

[fī′brō·mə]
(medicine)
A benign tumor composed primarily of fibrous connective tissue. Also known as fibroid tumor.

Fibroma

 

a mature benign tumor of connective tissue, which can occur in any part of the body. Fibromas may be diffuse or encapsulated, depending on the nature of their growth. Fibroblasts are the source of fibromas, hence their other name, fibroblastomas. The symptoms and the course of a fibroma depend on the site and the rate of growth. Malignant degeneration sometimes occurs. Fibromas are treated surgically.

The histogenesis and classification of fibrohistiocytic lesions involving bone and containing an admixture of fibrous tissue, foam cells, and giant cells are confusing and include several overlapping entities, such as metaphyseal fibrous defect, nonossifying fibroma, fibrous cortical defect, fibroxanthoma, and benign fibrous histiocytoma (BFH) of bone.
The nonossifying fibroma (ie, metaphyseal defect) is more cellular with a storiform pattern and characteristically has multinucleated giant cells, xanthoma cells, and hemosiderin pigment--loaded macrophages.
