| vaccine bodies | Old term pertaining to intracellular body's that were erroneously thought to be forms in the life cycle of a protozoan organism, Cytorrhyctes vaccinae, postulated to be the causal agent of vaccinia. (05 Mar 2000) |

| pacchionian bodies | Tufted prolongations of pia-arachnoid, composed of numerous arachnoid villi that penetrate dural venous sinuses and effect transfer of cerebrospinal fluid to the venous system. at advanced age these are more numerous and tend to calcify. Synonym: granulationes arachnoideales, arachnoidal granulations, pacchionian bodies, pacchionian corpuscles, pacchionian glands, pacchionian granulations. (05 Mar 2000) |
| Gamna-Favre bodies | Characteristic, relatively large, intracytoplasmic basophilic inclusion body's observed in endothelial cells in lymphogranuloma venereum; probably composed of degenerated nuclear material. See: Miyagawa bodies. (05 Mar 2000) |
| Gamna-Gandy bodies | Small firm spheroidal or irregular foci that are yellow-brown, brown, or rustlike in colour, occurring chiefly in the spleen in such conditions as congestive splenomegaly and sickle cell disease, and consisting of relatively dense fibrous tissue or collagenous fibres impregnated with iron pigment and calcium salts; probably result from organization and scarring of sites where small perivascular haemorrhages occurred. Synonym: Gamna-Gandy nodules, Gandy-Gamna bodies, siderotic nodules. (05 Mar 2000) |

| Mallory bodies | Large, poorly defined accumulations of eosinophilic material in the cytoplasm of damaged hepatic cells in certain forms of cirrhosis and marked fatty change especially due to alcoholism. Synonym: alcoholic hyalin, alcoholic hyaline bodies. (05 Mar 2000) |
| malpighian bodies | Small nodular masses of lymphoid tissue attached to the sides of the smaller arterial branches. Synonym: folliculi lymphatici lienales, malpighian bodies, malpighian corpuscles, malpighian glands, malpighian nodules, splenic corpuscles, splenic lymph nodules. (05 Mar 2000) |
| mamillary bodies | A pair of nuclei and associated gray matter in the interpeduncular space rostral to the posterior perforated substance in the posterior hypothalamus. (12 Dec 1998) |
| Pappenheimer bodies | Phagosomes, containing ferruginous granules, found in red blood cells in diseases such as sideroblastic anaemia, haemolytic anaemia, and sickle cell disease; may contribute to spurious platelet counts by electro-optical counters. (05 Mar 2000) |
| para-aortic bodies | Small masses of chromaffin cells found near the sympathetic ganglia along the abdominal aorta. They serve as chemoreceptors responsive to oxygen, carbon dioxide, and hydrogen ion concentration, and help to control respiration. (12 Dec 1998) |
| geniculate bodies | Part of the diencephalon inferior to the caudal end of the dorsal thalamus. Includes the lateral geniculate body which relays visual impulses from the optic tract to the calcarine cortex, and the medial geniculate body which relays auditory impulses from the lateral lemniscus to the auditory cortex. (12 Dec 1998) |
| Verocay bodies | Hyalinised acellular areas composed of reduplicated basement membrane outlined by opposing rows of prarallel nuclei; seen microscopically in neurilemomas. (05 Mar 2000) |
| Paschen bodies | Particles of virus observed in relatively large numbers in squamous cells of the skin (or the cornea of experimental animals) in variola (smallpox) or vaccinia. (05 Mar 2000) |
| Virchow-Hassall bodies | Small spherical bodies of keratinised and usually squamous epithelial cells arranged in a concentric pattern around clusters of degenerating lymphocytes, eosinophils, and macrophages; found in the medulla of the lobules of the thymus. Synonym: Hassall's bodies, Hassall's concentric corpuscle, Virchow-Hassall bodies. (05 Mar 2000) |
| pericanicular dense bodies | <cell biology> Electron dense membrane bounded cytoplasmic organelles found near the canaliculi in liver cells: lysosomes. (18 Nov 1997) |
