| 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) |
| foreign body granuloma | A granuloma caused by the presence of foreign particulate material in tissue, characterised by a histiocytic reaction with foreign body giant cells. (05 Mar 2000) |
| laryngeal granuloma | A polypoid granulomatous projection of granulomatous tissue into the lumen of the larynx, commonly following a traumatic tracheal intubation. (05 Mar 2000) |
| lethal midline 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) |
| lipoid granuloma | Granuloma characterised by aggregates or accumulations of fairly large mononuclear phagocytes that contain lipid. (05 Mar 2000) |
| lipophagic granuloma | A lesion formed as a result of the inflammatory reaction provoked by foci of necrosis in subcutaneous fat, as in certain types of traumatic injury; the central focus of necrotic material is surrounded by an irregular zone of numerous macrophages, many of which become laden with tiny globules of lipid.
