| desmoplastic fibroma n. A benign fibrous tumor of bone affecting children and young adults. |
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.
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.
