| Hassall's 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) |

| cytoplasmic inclusion bodies | See: inclusion bodies. (05 Mar 2000) |
| heinz bodies | Coccoid inclusion bodies resulting from oxidative injury to and precipitation of haemoglobin, seen in the presence of certain abnormal haemoglobins and erythrocytes with enzyme deficiencies. (12 Dec 1998) |
| sand bodies | Mineralised body's occurring in the meninges, choroid plexus, and in certain meningiomas; composed usually of a central capillary surrounded by concentric whorls of meningocytes in various stages of hyaline change and mineralization; can also occur in benign and malignant epithelial tumours (often papillary) or with chronic inflammation. Synonym: sand bodies. Synonym: corpora arenacea. Synonym: calcospherite. (05 Mar 2000) |
| Sandstrom's bodies | See: parathyroid gland. (05 Mar 2000) |

| Herring bodies | <pathology> Granules within axons in the posterior lobe of the pituitary gland. Contain neurosecretory hormones. (18 Nov 1997) |
| Prowazek bodies | Historic term for either of two types of inclusion body's associated with certain diseases: 1) trachoma body's; 2) tiny, ovoid, granular forms, frequently in pairs, observed in the cytoplasm and in Guarnieri body's in the cutaneous squamous cells of man and animals infected with variola (smallpox) or vaccinia virus; probably the same as Paschen body's. (05 Mar 2000) |
| Prowazek-Greeff bodies | Distinctive, complex, intracytoplasmic forms found in the conjunctival epithelial cells of persons in the acute phase of trachoma, less frequently in later stages, varying from 1) discrete acidophilic granules (approximately 250 nm in diameter), to 2) irregular clumps of such material embedded in a basophilic matrix, to 3) relatively large basophilic body's (approximately 700 to 1000 nm in diameter), to 4) large basophilic body's that include discrete, tiny, acidophilic granules. Synonym: Halberstaedter-Prowazek bodies, Prowazek-Greeff bodies. (05 Mar 2000) |
| psammoma bodies | Mineralised body's occurring in the meninges, choroid plexus, and in certain meningiomas; composed usually of a central capillary surrounded by concentric whorls of meningocytes in various stages of hyaline change and mineralization; can also occur in benign and malignant epithelial tumours (often papillary) or with chronic inflammation. Synonym: sand bodies. Synonym: corpora arenacea. Synonym: calcospherite. (05 Mar 2000) |
| sclerotic bodies | Vegetative rounded muriform cells of dematiaceous fungi, characteristic of the causal agents of chromoblastomycosis in tissue. Synonym: copper pennies. (05 Mar 2000) |
| psittacosis inclusion bodies | Intracytoplasmic chlamydial microcolonies observed in bronchial epithelial cells infected with Chlamydia psittaci. (05 Mar 2000) |
| Hirano bodies | Paracrystalline inclusions found in the brain of patients with neurodegenerative disorders. (18 Nov 1997) |
| Howell-Jolly bodies | Spherical or ovoid eccentrically located granules, approximately 1 um in diameter, occasionally observed in the stroma of circulating erythrocytes, especially in stained preparations (as compared with wet unstained films); probably represent nuclear remnants, inasmuch as they can be stained with dyes that are rather specific for chromatin; the significance of the body's is not exactly known; they occur most frequently after splenectomy or in megaloblastic or severe haemolytic anaemia. Synonym: Jolly bodies. (05 Mar 2000) |
