| giant pigmented nevus | These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma. A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation. (27 Sep 1997) |

| giant urticaria | A vascular reaction involving the deep dermis or subcutaneous or submucal tissues, representing localised oedema caused by dilatation and increased permeability of the capillaries and characterised by development of giant wheals. (18 Nov 1997) |
| congenital giant pigmented nevus | These large pigmented (often hairy) congenital nevi are important because of their increased risk (10 to 15%) of conversion into malignant melanoma. A biopsy can confirm if cells have turned malignant. Any change in a pre-existing nevus should prompt a physician evaluation. (27 Sep 1997) |
| squid giant axon | <physiology> Large axons, up to 1mm in diameter, that innervate the mantle of the squid. Because of their large size, many of the pioneering investigations of the mechanisms underlying resting and action potentials in excitable cells were done on these fibres. (10 Mar 1998) |
| Langhans'-type giant cells | Multinucleated giant cell's seen in tuberculosis and other granulomas; the nuclei are arranged in an arciform manner at the periphery of the cell's. Synonym: Langhans'-type giant cells. Synonym: cytotrophoblastic cells. (05 Mar 2000) |
| actinic granuloma | An annular eruption on sun-exposed skin which microscopically shows phagocytosis of dermal elastic fibres by giant cells and histiocytes. Synonym: Miescher's granuloma. (05 Mar 2000) |
| amoebic granuloma | A nodular, tumour-like focus of proliferative inflammation sometimes developing in chronic amoebiasis, especially in the wall of the colon. Synonym: amoebic granuloma. Origin: amoeba + G. -oma, tumour (05 Mar 2000) |
| apical granuloma | Chronic nonsuppurative inflammation of periapical tissue resulting from irritation following pulp disease or endodontic treatment. (12 Dec 1998) |
| beryllium granuloma | A sarcoid-like granulomatous reaction to exposure to inhaled beryllium, or skin cuts by fluorescent lamps. (05 Mar 2000) |
| bilharzial granuloma | A granulomatous lesion formed around schistosome eggs embedded in tissues in cases of schistosomiasis (bilharziasis); typically these granulomata are found in intestinal tissues (Schistosoma japonicum or S. Mansoni infection), bladder tissue (S. Haematobium), and hepatic tissue (all human schistosomes). Synonym: bilharzial granuloma. (05 Mar 2000) |
| canine venereal granuloma | A rapidly growing, soft, easily bleeding, infectious, connective tissue tumour occurring in the vagina of the female dog and on the penis and sheath of the male; ordinarily transmitted by coitus. Synonym: transmissible venereal tumour. (05 Mar 2000) |
| malignant granuloma | Destruction of the nasal septum, hard palate, lateral nasal walls, paranasal sinuses, skin of the face, orbit and nasopharynx by an inflammatory infiltrate with atypical lymphocytic and histiocytic cells; presumably a form of lymphoma in most cases. An obsolete term for polymorphic reticulosis. Synonym: granuloma gangrenescens, malignant granuloma, midline malignant reticulosis granuloma. (05 Mar 2000) |
| paracoccidioidal granuloma | A mycosis affecting the skin, mucous membranes, lymph nodes, and internal organs. It is caused by paracoccidioides brasiliensis. It is also called paracoccidioidal granuloma. (12 Dec 1998) |
| parasitic granuloma | Cutaneous leishmaniasis manifested as warty papules affecting primarily the lower limbs. (05 Mar 2000) |
| reticulohistiocytic granuloma | <tumour> Obsolete term for reticulohistiocytoma. (05 Mar 2000) |
