Forms: 1800s– rabdoid, 1800s– rhabdoid.

Origin: A borrowing from Latin. Etymon: Latin rabdoides.

Etymology: < post-classical Latin rabdoides (1679) < Hellenistic Greek ῥαβδοειδής striped < ancient Greek ῥάβδος rod (see rhabdo- comb. form) + -οειδής -oid suffix. Compare French rabdoïde (1756 or earlier), and also slightly earlier rhabdoidal adj. In sense B. 2 after German Rhabdoid (L. von Graff in Bronn's Thier-Reichs (1908) IV. i.c. 2032).

A. adj.

1. Resembling a rod; rod-shaped, rodlike; (Zoology) of or relating to rod-like structures secreted by turbellarian flatworms (see sense B. 2).

1992 Trans. Amer. Microsc. Soc. 111 112 Bothromesostoma personatum has numerous rhabdoid gland cells distributed throughout the parenchyma. Their secretory granules are rod-shaped.

2. Pathology. Characteristic of or resembling a rhabdomyosarcoma.

1979 Year Bk. Cancer 163 The other major sarcomatous pattern, termed ‘rhabdomyosarcomatoid’ (or ‘rhabdoid’) because of a strikingly myogenous appearance of the cytoplasm..is associated with a high incidence of hematogenous metastases.

1990 Diagnostic Cytopathol. 6 124 Rhabdoid cells—intermediate-sized cells with vesicular nuclei and prominent nucleoli, exhibiting a paranuclear, eosinophilic, dense inclusion—seem to be specific enough for this tumor to allow diagnosis by FNAC [= fine-needle aspiration cytology].

2008 R. O. Petersen et al. Urologic Pathol. (ed. 2) 52 Reports of intracytoplasmic pigment, hyaline globules, and rhabdoid features are documented in the literature.

B. n.

1. Botany. A rodlike cytoplasmic body seen in the sensitive cells of various insectivorous plants of the family Droseraceae. Now disused.

1885 W. Gardiner in Proc. Royal. Soc. 39 234 I have decided to name this body which I have provisionally spoken of as the plastoid ‘the rabdoid’.

1908 F. Darwin in C. Darwin Insectivorous Plants (rev. ed.) 32/1 Mr. W. Gardiner..has described a remarkable body named by him the ‘rhabdoid’, which exists in the epidermic cells of the tentacles [of Drosera].

1917 Bull. Torrey Bot. Club 44 393 When plants are deprived of insectivorous food for any considerable period, the rabdoids dwindle until they are barely noticeable.

2. Zoology. Any of the small rodlike structures which are secreted by the epidermis of turbellarian flatworms and dissolve to form a protective coating of mucus. Cf. rhabdite n. 3.
