1. Originally: any tumour having a mucoid stroma. Later: spec. a usually benign tumour consisting of scattered stellate or spindle cells in abundant mucoid stroma, probably originating from primitive mesenchymal cells, which may occur at a variety of sites and is the most common primary tumour of the heart.

1860 F. Chance tr. R. Virchow Cellular Pathol. xx. 480 Now since I had named the tissue of the umbilical cord and analogous parts, mucous tissue, it was a very simple step for me to call these tumours Mucous tumours (Schleimgeschwülste), Myxomata.
1870 Brit. Med. Jrnl. 3 Dec. 617/2 Mr. Arnott exhibited a specimen of Concurrent Myxoma from the gluteal region.
1901 Science 29 Mar. 495/2 The least differentiated or specialized cells of all, namely, the mesenchymal cells, are the ones that produce the greatest variety of tumors—..myxoma, myoma [etc.].
1949 H. W. C. Vines Green's Man. Pathol. (ed. 17) xv. 375 True myxomata consist of a fragile connective tissue of which the intercellular substance is translucent, homogeneous, and jelly-like, containing much fluid and yielding mucin, resembling the tissue of the umbilical cord, in which the cells are fusiform or stellate.
1975 Cancer 36 985 The staining reaction of intramuscular myxoma and myxoid liposarcoma corresponded to that of synovial fluid and cock's comb (containing hyaluronic acid).
1997 Ann. Thoracic Surg. 64 872 The clinical presentation of mitral valve myxoma differs slightly from that of other cardiac myxomas.
2. More fully infectious myxoma: the rabbit disease myxomatosis (now rare). Also: each of the lumpy inflammatory skin lesions, histologically resembling myxomas, which are characteristic of this disease.

1927 Memorias Inst. Oswaldo Cruz 20 243/2 Our research on the subject led us to ascertain in myxoma of rabbits the existence of a micro-organism similar to that of variola.
1930 Jrnl. Exper. Med. 51 966 The infectious myxoma of rabbits..is one of the first maladies placed in the virus group.
1931 Science 23 Jan. 94/2 The rabbits inoculated with the immune serum mixtures never showed any signs of myxoma at the sites of inoculation or elsewhere.
1965 F. Fenner & F. N. Ratcliffe Myxomatosis viii. 106 The term myxoma is somewhat misleading, for even the large lumps found in the skin are hardly true tumours.
1983 Jrnl. National Cancer Inst. 71 91 The epidermis overlying the myxomas showed cytoplasmic virus inclusions.
2001 Jrnl. Gen. Virol. 82 1407 In rabbits infected with a Serp3 deletion mutant..the main histopathological feature is the absence of secondary myxomas.
Compounds
myxoma virus n. the poxvirus (genus Leporipoxvirus) that is the cause of myxomatosis in the European rabbit ( Oryctolagus cuniculus).The natural hosts are certain American rabbits of the genus Sylvilagus, in which the virus causes a mild disease with localized tumours.
ΚΠ
1930 Jrnl. Exper. Med. 51 966 The myxoma virus is capable of passing through filters impervious to ordinary bacteria.
1966 Jrnl. Animal Ecol. 35 395 One of the first tasks of the Wildlife Survey Section, of the (Australian) Commonwealth Scientific and Industrial Research Organization,..was to reconsider the use of myxoma virus for the biological control of the wild rabbit.
1993 Science 6 Aug. 683/3 The next step is to insert a rabbit sperm antigen into the myxoma virus.
