| myxoma enchondromatosum | <tumour> A benign neoplasm of cartilaginous tissue, i.e., a chondroma, in which the stroma resembles relatively primitive mesenchymal tissue. Synonym: myxoma enchondromatosum. Origin: myxo-+ G. Chondros, cartilage, + -oma, tumour (05 Mar 2000) |

| myxoma sarcomatosum | A sarcoma, usually a liposarcoma or malignant fibrous histiocytoma, with an abundant component of myxoid tissue resembling primitive mesenchyme containing connective tissue mucin. (12 Dec 1998) |
| myxoma virus | <virology> A poxvirus (see Poxviridae) that causes myxomatosis. Originally isolated from a species of wild rabbit, Sylvilagus in Brazil, in which it causes a mild nonfatal disease, it was found to be 99% fatal in the European rabbit Oryctolagus. It causes the characteristic, sub cutaneous gelatinous swellings, myxomata and usually kills in 2-5 days. It has been used to control rabbit populations in Australia and Britain, but there are signs that they have developed immunity. (18 Nov 1997) |
| myxomatosis | 1. A fatal disease of European rabbits (Oryctolagus cuniculus) marked by purulent conjunctivitis and the development of myxomatous growths in the skin; caused by rabbit myxoma virus, a member of the family Poxviridae, and transmitted mechanically by mosquitoes; natural hosts are rabbits of the genus Sylvilagus in California and Brazil, in which the infection is not fatal and causes only local swelling. Synonym: mucoid degeneration. 3. Multiple myxomas. (05 Mar 2000) |
| myxomatosis virus | The poxvirus of the genus Leporipoxvirus causing myxomatosis of rabbits. Synonym: myxomatosis virus. (05 Mar 2000) |
| myxomatous | 1. Pertaining to or characterised by the features of a myxoma. 2. Said of tissue that resembles primitive mesenchymal tissue. (05 Mar 2000) |
| myxomembranous colitis | An affection of the mucous membrane of the colon characterised by colicky pain, constipation or diarrhoea (sometimes alternating), and passage of mucous or slimy pseudomembranous shreds and patches. Synonym: mucocolitis, myxomembranous colitis. (05 Mar 2000) |
| myxomycete | A member of the class Myxomycetes. (05 Mar 2000) |
| Myxomycetes | A class of fungi containing the slime molds, which occur on rotting vegetation but are not pathogenic for humans. Origin: myxo-+ G. Mykes, fungus (05 Mar 2000) |
| myxomycota | A division of organisms that exist vegetatively as complex mobile plasmodia, reproduce by means of spores, and have complex life cycles. They are usually classed as fungi, but some authorities, following de bary, 1859, regard them as protozoans. (12 Dec 1998) |
| myxoneuroma | 1. Obsolete term for a tumefaction resulting from abnormal proliferation of Schwann cells, in which focal or diffuse degenerative changes result in portions that resemble primitive mesenchymal tissue. 2. Obsolete term for a neurilemoma, meningioma, or glioma in which the stroma is myxomatous in nature. Origin: myxo-+ G. Neuron, nerve, + -oma, tumour (05 Mar 2000) |
