| granuloma faciale | <dermatology> Persistent well-demarcated nodules that usually appear on the face and consist of a dense dermal infiltrate of eosinophils and neutrophils, separated from the epidermis and hair follicles, with fibrinoid vasculitis. (05 Mar 2000) |
| granuloma gangrenescens | 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) |
| granuloma gravidarum | A pyogenic granuloma developing on the gingiva during pregnancy; thought to be related to hormonally altered response of the oral mucous membranes to local irritants such as bacterial plaque on adjacent teeth. Synonym: pregnancy tumour. (05 Mar 2000) |
| granuloma inguinale | <disease, microbiology> A rare sexually transmitted disease that is caused by Calymmatobacterium granulomatis. This infection is more common in the tropical and subtropical areas such as India, Guyana and new Guinea. There are approximately 100 cases reported annually in the United States. Men are affected more often than women. It is thought to be most commonly acquired through anal intercourse. Symptoms include a small red nodule on the genitalia that may form elevated masses of reddened tissue (granulation tissue). The lesions gradual spread and destroy genital tissue. Diagnosis is via tissue biopsy or culture. Treatment includes antibiotics. (27 Sep 1997) |
| granuloma inguinale tropicum | An elongated ulcer, with elevated papillary edges, sometimes occurring in the groin in persons in the tropics. Synonym: groin ulcer. (05 Mar 2000) |

| granuloma pudendi | <disease, microbiology> A rare sexually transmitted disease that is caused by Calymmatobacterium granulomatis. This infection is more common in the tropical and subtropical areas such as India, Guyana and new Guinea. There are approximately 100 cases reported annually in the United States. Men are affected more often than women. It is thought to be most commonly acquired through anal intercourse.

Diagnosis is via tissue biopsy or culture. Treatment includes antibiotics. (27 Sep 1997) |
| granuloma telangiectaticum | Granuloma pyogenicum, an acquired small rounded mass of highly vascular granulation tissue, frequently with an ulcerated surface, projecting from the skin or mucosa; histologically, the mass resembles a capillary haemangioma. Synonym: granuloma telangiectaticum. (05 Mar 2000) |
| granuloma tropicum | <medicine> A disease, occurring in the Antilles and in Africa, characterised by yellowish or reddish tumours, of a contagious character, which, in shape and appearance, often resemble currants, strawberries, or raspberries. There are several varieties of this disease, variously known as framboesia, pian, verrugas, and crab-yaws. Origin: African yaw a raspberry. Source: Websters Dictionary (01 Mar 1998) |
| granuloma venereum | <disease, microbiology> A rare sexually transmitted disease that is caused by Calymmatobacterium granulomatis. This infection is more common in the tropical and subtropical areas such as India, Guyana and new Guinea. There are approximately 100 cases reported annually in the United States. Men are affected more often than women. It is thought to be most commonly acquired through anal intercourse.

| granuloma, fish bowl | Localised nodular skin inflammation (small reddish raised areas of skin) caused by a bacterium called mycobacterium marinum. Fish bowl granuloma is typically acquired by occupational or recreational exposure to salt or fresh water, often resulting from minor trauma during caring for aquariums. The diagnosis is suggested by the history of exposure and confirmed by culturing tissue specimens which yield the microscopic organism, mycobacterium marinum. The infection can be treated with a variety of antibiotics, including doxycycline, minocycline, clarithromycin, rifampin, and trimethoprim-sulfamethoxazole. Also called swimming pool granuloma. (12 Dec 1998) |
| granuloma, foreign-body | Histiocytic, inflammatory response to a foreign body. It consists of modified macrophages with multinucleated giant cells, in this case foreign-body giant cells (giant cells, foreign-b0dy), usually surrounded by lymphocytes. (12 Dec 1998) |
| granuloma, laryngeal | A polypoid granulomatous projection into the lumen of the larynx. (12 Dec 1998) |
| granuloma, lethal midline | A non-neoplastic disease of unknown aetiology beginning with inflammation, ulceration, and perforation of nose and palate and progressing to gradual destruction of midline facial structures. (12 Dec 1998) |
| Graham Steell's murmur |
a high-pitched diastolic murmur caused by pulmonary regurgitation secondary to severe pulmonary hypertension; it is heard at the left sternal edge, level with the second or third costal cartilage.
