Med. 1876). ˌrhabdomyosarˈcoma Path., a malignant neoplasm of skeletal muscle (malignant rhabdomyoma), or (but see quots. 1958, 1976) of embryonic tissue. ‖ rhabdoˈnema [Gr. νῆµα thread], a minute slender worm living in the duodenum. ˈrhabdophane, rhabˈdophanite [Gr. -ϕανής appearing], see quots.: identified with scovillite. ˈrhabdopod, one of the clasping organs of the Ephemeridæ. ‖ rhabdosarˈcoma (see quot.). ˈrhabdosome, † -soma Palæont. [Gr. σῶµα body], a colony of conjoined graptolites. ˈrhabdosphere, a name given to certain spherical bodies found in abundance on the surface of the waters in warm seas. ˈrhabdovirus Biol., any of the group of RNA viruses that includes the rabies virus.

| 1956 D. H. Bowden et al. in Medicine XXXV. 351 Biochemical and histological data have been obtained in three children with paroxysmal myohaemoglobinuria. These findings indicate that the recurrent symptom complex is the result of a pathological process in which striated muscle suddenly undergoes lysis. As a more satisfactory description of the disease, we propose that the condition be renamed acute recurrent *rhabdomyolysis. 1963 Amer. Jrnl. Med. XXXIV. 554/1 Idiopathic recurrent rhabdomyolysis with myoglobinuria is a syndrome characterized by acute skeletal muscle weakness and pain associated with the passage of urine that is darkly pigmented owing to myoglobin. 1976 Lancet 18 Dec. 1343/1 Rhabdomyolysis is usually caused by serious muscle trauma (crush injuries), electric shock, arterial occlusion, or toxins (drugs, sea-snake bite). |

Ophthalm. Soc. LXXVIII. 96 The exact cytological classification may eventually prove to be important from the prognostic and therapeutic point of view, so that the term rhabdomyosarcoma should not be applied unless striations have been demonstrated unequivocally. 1974 J. R. Wilbur et al. in Neoplasia of Head & Neck 281 Rhabdomyosarcoma is the most common soft tissue sarcoma in children. 1976 Proc. R. Soc. Med. LXIX. 897/1 It has been suggested (Ashton 1958) that all such tumours should be regarded as embryonal sarcomas because of their origin from undifferentiated foci of mesenchymal cells, and that the term ‘rhabdomyosarcoma’ should be applied only when there is evidence of longitudinal and cross-striations in the tumour cells, an indication perhaps of some degree of differentiation. |
