| 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) |
| pulse granuloma | <pathology> An inflammatory infiltrate containing foreign body giant cells and eosinophilic material. Fragments of foreign material resembling vegetable matter may be included. Synonym: pulse granuloma. (05 Mar 2000) |
| pyogenic granuloma | 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) |
| silica granuloma | Eruption of granulomatous lesions due to traumatic inoculation of the skin with sand, or materials that contain silica; this condition may follow dermabrasion using sandpaper technique. (05 Mar 2000) |
| silicotic granuloma | Granulomatous nodule resulting from deposition of silica particles, usually occurring in lung. (05 Mar 2000) |
| sporothrix granuloma | <dermatology> A fungal skin infection caused by the fungus Sporothrix schenckii and commonly seen in gardeners. (06 Mar 1998) |
| swimming pool granuloma | 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) |
| dental granuloma | Chronic nonsuppurative inflammation of periapical tissue resulting from irritation following pulp disease or endodontic treatment. (12 Dec 1998) |
| infectious granuloma | Any granulomatous lesion known to be caused by a living agent; e.g., bacteria, fungi, helminths. (05 Mar 2000) |
