| 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) |
| telangiectatic fibroma | <tumour> A benign neoplasm of fibrous tissue in which there are numerous, small and large, frequently dilated, vascular channels. Synonym: angiofibroma. (05 Mar 2000) |
| fibroma | <oncology, tumour> A benign (non-cancerous) tumour which consists of fibrous tissues or connective tissue. (09 Oct 1997) |
| 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 molle | A polypoid outgrowth of both epidermis and dermal fibrovascular tissue, common terminology for any small benign cutaneous lesion. Synonym: acrochordon, fibroepithelial polyp, fibroma molle, senile fibroma, soft wart. (05 Mar 2000) |
| fibroma molle gravidarum | Skin tags or polyps that develop on women during pregnancy and often disappear at term. (05 Mar 2000) |
| 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) |
| fibroma virus, rabbit | A species of leporipoxvirus causing subcutaneous localised swellings in rabbits, usually on the feet. (12 Dec 1998) |
| adenoid cystic carcinoma | <tumour> A histologic type of carcinoma characterised by large epithelial masses containing round, glandlike spaces or cysts which frequently contain mucus or collagen and are bordered by a few or many layers of epithelial cells without intervening stroma, forming a cribriform pattern like a slice of Swiss cheese; perineural invasion and haematogenous metastasis are common; occurs most commonly in salivary glands. Synonym: cylindromatous carcinoma. (05 Mar 2000) |
| carcinoma, adenoid cystic | Carcinoma characterised by bands or cylinders of hyalinised or mucinous stroma separating or surrounded by nests or cords of small epithelial cells. When the cylinders occur within masses of epithelial cells, they give the tissue a perforated, sievelike, or cribriform appearance. Such tumours occur in the mammary glands, the mucous glands of the upper and lower respiratory tract, and the salivary glands. They are malignant but slow-growing, and tend to spread locally via the nerves. (12 Dec 1998) |
