fibroma /fi·bro·ma/ (fi-bro´mah) pl. fibromas, fibro´mata   a tumor composed mainly of fibrous or fully developed connective tissue.

---

ameloblastic fibroma  an odontogenic tumor marked by simultaneous proliferation of both epithelial and mesenchymal tissue, without formation of enamel or dentin.

cementifying fibroma  a tumor of fibroblastic tissue containing masses of cementum-like tissue, usually in the mandible of older persons.

chondromyxoid fibroma  a rare, benign, slowly growing tumor of bone of chondroblastic origin, usually affecting the large long bones of the lower limb.

cystic fibroma  one that has undergone cystic degeneration.

fibroma mollus´cum  small subcutaneous nodules scattered over the body surface; seen in some forms of neurofibromatosis.

nonossifying fibroma , nonosteogenic fibroma a degenerative and proliferative lesion of the medullary and cortical tissues of bone.

ossifying fibroma , ossifying fibroma of bone a benign, slow-growing, central bone tumor, usually of the jaws, especially the mandible, composed of fibrous connective tissue within which bone is formed.

perifollicular fibroma  one or more small, flesh-colored, papular, follicular lesions on the head and neck.

peripheral ossifying fibroma  epulis; a fibroma, usually of the gingiva, showing areas of calcification or ossification.

n.

A gingival fibroma derived from cells of the periodontal ligament and usually developing in response to local irritants such as plaque and calculus on associated teeth.

fibroma (fībrō´m),

n a benign mesenchymal tumor composed primarily of fibrous connective tissue.

fibroma, ameloblastic,

n a mixed tumor of odontogenic origin characterized by the simultaneous proliferation of both the epithelial and mesenchymal components of the tooth germ without the production of hard structure.

fibroma, calcifying,

n See fibroma, ossifying.

fibroma, cementifying,

n an intrabony lesion not associated with teeth, composed of a fibrous connective tissue stroma containing foci of calcified material resembling cementum; a rare odontogenic tumor composed of varying amounts of fibrous connective tissue with calcified material resembling cementum. Central lesion of the jaws.

n a fibrous bone tumor, usually benign, found most commonly in children and young adults.

fibroma, irritation,

n a localized peripheral, tumorlike enlargement of connective tissue caused by prolonged local irritation and usually seen on the gingiva or buccal mucosa.

Irritational fibroma.

fibroma, neurogenic,

n See neurilemoma; neurofibroma.

fibroma, odontogenic,

n a central odontogenic tumor of the jaws, consisting of connective tissue in which small islands and strands of odontogenic epithelium are dispersed. A mesodermal odontogenic tumor composed of active dense or loose fibrous connective tissue; contains inactive islands of epithelium.

fibroma, ossifying,

n a benign neoplasm of bone characterized by unilateral swelling and fibroblastic and osteoblastic activity in marrow spaces. An aggressive variant of this lesion has been described and is termed juvenile ossifying fibroma or juvenile active ossifying fibroma.

(benign periapical fibroma, fibrous dysplasia, first-state cementoma, focal osseous dysplasia, traumatic osteoclasia),
n a benign connective tissue mass formed at the apex of a tooth with a normal pulp.

fibroma, peripheral odontogenic,

n a fibrous connective tissue tumor associated with the gingival margin and believed to originate from the periodontium. Often contains areas of calcification. Localized form of fibromatosis gingivae.

fibroma, peripheral ossifying,

n a type of reactive gingival growth that appears most commonly in teenagers and young adults. They can be surgically removed, but rate of recurrence is high.

fibroma, with myxomatous degeneration,

n See fibromyxoma.
