|---|
| Shope fibroma | A connective tissue tumour of cottontail rabbits caused by a poxvirus of the genus Leporipoxvirus and found by Shope to be transmissible with cellular suspensions or Berkefeld filtrates; it is related to myxomatosis and is used in Europe as a source of vaccine to protect against the myxoma virus. Synonym: rabbit fibroma. (05 Mar 2000) |

| Shope papilloma virus | <virology> Papovavirus that produces papillomas (warts) in rabbits. (18 Nov 1997) |
| Shope papilloma | A papillomatous growth found in wild cottontail rabbits that is caused by a virus in the family Papovaviridae and can be transferred to domestic rabbits where it will cause similar growths. A high percentage of these growths may become malignant. (05 Mar 2000) |
| Shope, Richard | <person> U.S. Pathologist, 1902-1966. See: Shope fibroma, Shope fibroma virus, Shope papilloma, Shope papilloma virus. (05 Mar 2000) |
| rabbit fibroma virus | A poxvirus of the genus Leporipoxvirus, closely related to vaccinia and myxoma viruses, that causes Shope fibroma. Synonym: fibromatosis virus of rabbits, Shope fibroma virus. (05 Mar 2000) |
| fibroma virus, rabbit | A species of leporipoxvirus causing subcutaneous localised swellings in rabbits, usually on the feet. (12 Dec 1998) |
| ameloblastic fibroma | <tumour> A benign mixed odontogenic tumour characterised by neoplastic proliferation of both epithelial and mesenchymal components of the tooth bud without the production of dental hard tissue; presents clinically as a slow-growing painless radiolucency occurring most commonly in the mandible of children and adolescents. (05 Mar 2000) |
| aponeurotic fibroma | <tumour> A calcifying recurrent non-metastasizing but infiltrating fibroma seen most frequently on the palms of young people as a small firm nodule not attached to the overlying skin. (05 Mar 2000) |
| rabbit fibroma | A connective tissue tumour of cottontail rabbits caused by a poxvirus of the genus Leporipoxvirus and found by Shope to be transmissible with cellular suspensions or Berkefeld filtrates; it is related to myxomatosis and is used in Europe as a source of vaccine to protect against the myxoma virus. Synonym: rabbit fibroma. (05 Mar 2000) |
| giant cell fibroma | <tumour> A tumour of the oral mucosa composed of fibrous connective tissue with large stellate and multinucleate fibroblasts; shares a similar histology with the retrocuspid papilla, fibrous papule of the nose, pearly penile papule, and the ungual fibroma. (05 Mar 2000) |
| central cementifying fibroma | <tumour> A microscopic variant of a central ossifying fibroma. (05 Mar 2000) |
| central ossifying fibroma | <tumour> A painless, slow-growing, expansile, sharply circumscribed benign fibro-osseus tumour of the jaws that is derived from cells of the periodontal ligament; presents initially as a radiolucency that becomes progressively more opaque as it matures. See: central cementifying fibroma. (05 Mar 2000) |
| peripheral ossifying fibroma | A reactive focal gingival overgrowth derived histogenetically from cells of the periodontal ligament and usually developing in response to local irritants (plaque and calculus) on associated teeth; consists microscopically of a hyperplastic cellular fibrous stroma supporting deposits of bone, cementum, or dystrophic calcification. (05 Mar 2000) |
| periungual fibroma | Multiple smooth firm nodules formed at the nail folds, often over 10 mm in length, which appear at or after puberty in some patients with tuberous sclerosis. Synonym: Koenen's tumour. (05 Mar 2000) |
