| 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) |

| nonossifying fibroma | <tumour> A loculated osteolytic focus of cellular fibrous tissue, slightly expanding a bone, usually near the end of a long bone in older children; similar to fibrous cortical defect, although larger. (05 Mar 2000) |
| nonosteogenic fibroma | A common 1 to 3 cm defect in the cortex of a bone, most commonly the lower femoral shaft of a child, filled with fibrous tissue. Nonosteogenic or nonossifying fibroma by convention refers to lesions greater than 3 cm in diameter. See: nonossifying fibroma. Synonym: nonosteogenic fibroma. (05 Mar 2000) |
| desmoplastic fibroma | <tumour> A benign fibrous tumour of bone affecting children and young adults; cortical destruction may result. (05 Mar 2000) |
| irritation fibroma | A slow-growing nodule on the oral mucosa, composed of fibrous tissue covered by epithelium, resulting from mechanical irritation by dentures, fillings, cheek biting, etc. (05 Mar 2000) |
| odontogenic fibroma | <tumour> A rare odontogenic tumour found in soft tissue or as a central bony lesion. The tumour is composed of fibrous connective tissue, odontogenic epithelium, and sometimes calcification. (05 Mar 2000) |
| ovarian fibroma | <radiology> Bilateral in 10%, malignant counterpart (fibrosarcoma) very rare, associated with Meigs syndrome (12 Dec 1998) |

| fibroma, desmoplastic | A extremely rare bone tumour characterised by abundant collagen formation and a fibrous stroma, without evidence of mitosis or pleomorphism. It appears on X-rays as an osteolytic lesion with well-defined margins and must be differentiated from primary fibrosarcoma of bone. (devita jr et al., cancer: principles & practice of oncology, 3d ed, p1441) (12 Dec 1998) |
| fibroma myxomatodes | <tumour> A benign neoplasm of fibrous connective tissue that resembles primitive mesenchymal tissue. Synonym: fibroma myxomatodes, myxoma fibrosum. Origin: myxo-+ L. Fibra, fibre, + G. -oma, tumour (05 Mar 2000) |
| fibroma, ossifying | A benign, relatively slow-growing, central bone tumour, usually of the jaws (especially the mandible) which is composed of fibrous connective tissue within which bone is formed. (12 Dec 1998) |
