fibroma

 [fi-bro´mah] (pl. fibromas, fibro´�mata)
a tumor composed mainly of fibrous or fully developed connective tissue. Called also fibroid and fibroid tumor.
ameloblastic fibroma an odontogenic fibroma, marked by simultaneous proliferation of both epithelial and mesenchymal tissue, without formation of enamel or dentin.
cementifying fibroma cementoblastoma; a tumor usually occurring in the mandible of older persons and consisting of fibroblastic tissue containing masses of cementum-like tissue.
chondromyxoid fibroma of bone a benign slowly growing tumor of chondroblastic origin, usually affecting the long bones of the lower limb.
cystic fibroma one that has undergone cystic degeneration.
fibroma myxomato´des myxofibroma.
nonosteogenic fibroma a degenerative and proliferative lesion of the medullary and cortical tissues of bone.
odontogenic fibroma a rare benign tumor of the jaw arising from the embryonic portion of the tooth germ, the dental papilla, or dental follicle.
ossifying fibroma (ossifying fibroma of bone) a benign, relatively slow-growing, central bone tumor, usually of the jaws, especially the mandible, which is composed of fibrous connective tissue within which bone is formed.

osteofibrous dysplasia

A rare, self-limiting non-neoplastic lesion which usually arises in the cortex of the tibia and fibula, or both, most often in the middle third of the diaphysis, affecting children < age 15.
 
Clinical findings
Pain, pathological fracture, swelling, deformity; may be asymptomatic for up to 5 years.

Imaging
Well-defined intramedullary lytic lesion with a sclerotic rim; the cortex often is expanded and thinned, with multiple radiolucencies admixed with intervening areas of sclerosis.
