| granuloma, pyogenic | A usually solitary polypoid capillary haemangioma of the skin and gingival or oral mucosa, often associated with trauma or local irritation, representing a vasoproliferative inflammatory response. It presents as a small erythematous papule that enlarges and may become pedunculated and may become infected and ulcerate with accompanying purulent exudate. The haemangioma without suppuration is called angiogranuloma. Pyogenic granuloma is not a granuloma: the name refers to the mass of inflamed, highly vascular granulation tissue. (12 Dec 1998) |

| granuloma, respiratory tract | Granulomatous diseases affecting one or more sites in the respiratory tract. (12 Dec 1998) |
| granuloma, swimming pool | Localised nodular skin inflammation (small reddish raised areas of skin) caused by a bacterium called mycobacterium marinum. Swimming pool 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 fish bowl granuloma. (12 Dec 1998) |
| 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. 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) |
| root end granuloma | Chronic nonsuppurative inflammation of periapical tissue resulting from irritation following pulp disease or endodontic treatment. (12 Dec 1998) |
| rose growers granuloma | <dermatology> A fungal skin infection caused by the fungus Sporothrix schenckii and commonly seen in gardeners. (27 Sep 1997) |
| midline malignant reticulosis 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) |
| Miescher's 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) |
| coccidioidal granuloma | Progressive or disseminated extrapulmonary granulomatous lesions following primary coccidioidomycosis. Synonym: coccidioidal granuloma. (05 Mar 2000) |
| coli granuloma | <veterinary> A granulomatous disease of the intestines and liver of chickens, due to coliform organisms. Synonym: coli granuloma. (05 Mar 2000) |
| sarcoidal granuloma | A non-necrotizing epithelioid cell granuloma similar to those seen in sarcoidosis. (05 Mar 2000) |
| schistosome 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) |
| sea urchin granuloma | Granulomatous nodules, either foreign-body type or composed of epitheliod cells, from the retention of the spine of the sea urchin, occurring several months after the wounding of the skin. (05 Mar 2000) |
