| 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) |
| oily granuloma | Reaction to inclusion of a bulky, insoluble liquid (often an oily substance) which occurs several months, but sometimes years, after injection of the material. (05 Mar 2000) |
| eosinophilic granuloma | <oncology, tumour> An immunologic disorder of unknown cause where there is proliferation of histiocytes (a type of cell in the immune system) in the bloodstream. The disorder is characterised by inflammation of the bronchioles and small pulmonary vessels that leads to fibrosis and destruction of alveolar cell walls. Cigarette smoking is considered a risk factor. Individuals with this disorder are also at increased risk for spontaneous pneumothorax. Symptoms include cough, chest pains, shortness of breath, fever, weight loss and malaise. Bronchoscopy with biopsy confirms the diagnosis. Childhood forms exist and cause more systemic symptoms and findings such as failure to thrive, weight loss, fevers, irritability, rash and bone pains. Treatment is with corticosteroids.

| ulcerating granuloma of pudenda | <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) |
| zirconium granuloma | Granuloma from zirconium salts, usually occurring in the axillae, from antiperspirants containing this material; may also be caused by intradermal injection of antigens containing the lactate salt. (05 Mar 2000) |
| fish bowl granuloma | 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.
