| foreign body giant cell | <pathology> Syncytium formed by the fusion of macrophages in response to an indigestible particle too large to be phagocytosed for example talc, silica or asbestos fibres). There may be as many as 100 nuclei randomly distributed: similar cells but with the nuclei more peripherally located (Langhans cells) are found at the centre of tuberculous lesions. (06 Mar 1998) |

| foreign body granuloma | A granuloma caused by the presence of foreign particulate material in tissue, characterised by a histiocytic reaction with foreign body giant cells. (05 Mar 2000) |
| foreign-body migration | Migration of a foreign body from its original location to some other location in the body. (12 Dec 1998) |
| foreign-body reaction | Chronic inflammation and granuloma formation around irritating foreign bodies. (12 Dec 1998) |
| foreign body salpingitis | Salpingitis in which giant cells form in the tissue, as a result of introduction of foreign material into the fallopian tube. (05 Mar 2000) |
| foreign body tumourigenesis | Induction of malignant tumours in tissues by nonviable, nonabsorable solid material not known to contain a chemical carcinogen. (05 Mar 2000) |
| L-D body | The intracytoplasmic, nonflagellated leishmanial form of certain intracellular parasites, such as species of Leishmania or the intracellular form of Trypanosoma cruzi; originally used for Leishmania donovani parasites in infected spleen or liver cells in kala azar. Synonym: amastigote, L-D body. (05 Mar 2000) |
| LE body | <pathology> A globular mass of nuclear material that stains with haematoxylin, associated with lesions of systemic lupus erythematosus. (18 Nov 1997) |
| Leishman-Donovan body | The intracytoplasmic, nonflagellated leishmanial form of certain intracellular parasites, such as species of Leishmania or the intracellular form of Trypanosoma cruzi; originally used for Leishmania donovani parasites in infected spleen or liver cells in kala azar. Synonym: amastigote, L-D body. (05 Mar 2000) |
| fruiting body | <microbiology, plant biology> A macroscopic reproductive structure produced by some fungi (for example, mushrooms) and some bacteria (for example, myxobacteria). Fruiting bodies are distinct in size, shape, and colouration for each species. (13 Nov 1997) |
| Lieutaud's body | A triangular smooth area at the base of the bladder between the openings of the two ureters and that of the urethra. Synonym: trigonum vesicae, Lieutaud's body, Lieutaud's triangle, Lieutaud's trigone, vesical triangle. (05 Mar 2000) |

| loose body | A solid tissue fragment lying free in a body cavity, especially in a joint or the peritoneal cavity; e.g., joint mice, melon-seed body, rice body. (05 Mar 2000) |
| lower body negative pressure | External decompression applied to the lower body. It is used to study orthostatic intolerance and the effects of gravitation and acceleration, to produce simulated haemorrhage in physiologic research, to assess cardiovascular function, and to reduce abdominal stress during childbirth. (12 Dec 1998) |
| lung foreign body | Any object or material that does not belong in the respiratory tree. Lung foreign bodies most often result from the accidental aspiration of an object or food particle. (27 Sep 1997) |
