| erythema multiforme | <dermatology> A rash that results from an allergic response, most often secondary to a drug. The rash is described as pink-red macules (flat), that may have clear centres (iris lesions) or appear as a dusky violet colour. Erythema multiforme most often results from reactions to sulpha drugs, penicillin's, phenytoin, barbiturates, phenolphthalein and carbamazepine. In some cases, erythema multiforme can result secondary to a Herpes simplex infection or Mycoplasma infection. (27 Sep 1997) |
| erythema multiforme bullosum | <syndrome> This is a severe form of allergic reaction that most often results from a medication (for example penicillins). The rash can be generalised and even appear on the palms of the hands and soles of the feet. Stevens-Johnson syndrome is considered to be a variant of erythema multiforme that results in the formation of bullous (blebs) lesions on the soles of the feet, palms and inside the mouth. Stevens-Johnson syndrome may also occur in association with some viral infections and Mycoplasma infections. (27 Sep 1997) |
| erythema multiforme exudativum | <syndrome> This is a severe form of allergic reaction that most often results from a medication (for example penicillins). The rash can be generalised and even appear on the palms of the hands and soles of the feet. Stevens-Johnson syndrome is considered to be a variant of erythema multiforme that results in the formation of bullous (blebs) lesions on the soles of the feet, palms and inside the mouth. Stevens-Johnson syndrome may also occur in association with some viral infections and Mycoplasma infections. (27 Sep 1997) |
| erythema multiforme major | <syndrome> This is a severe form of allergic reaction that most often results from a medication (for example penicillins). The rash can be generalised and even appear on the palms of the hands and soles of the feet. Stevens-Johnson syndrome is considered to be a variant of erythema multiforme that results in the formation of bullous (blebs) lesions on the soles of the feet, palms and inside the mouth. Stevens-Johnson syndrome may also occur in association with some viral infections and Mycoplasma infections. (27 Sep 1997) |

| amoebic granuloma | A nodular, tumour-like focus of proliferative inflammation sometimes developing in chronic amoebiasis, especially in the wall of the colon. Synonym: amoebic granuloma. Origin: amoeba + G. -oma, tumour (05 Mar 2000) |

| bilharzial 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) |
| canine venereal granuloma | A rapidly growing, soft, easily bleeding, infectious, connective tissue tumour occurring in the vagina of the female dog and on the penis and sheath of the male; ordinarily transmitted by coitus. Synonym: transmissible venereal tumour. (05 Mar 2000) |
| malignant 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) |
| paracoccidioidal granuloma | A mycosis affecting the skin, mucous membranes, lymph nodes, and internal organs. It is caused by paracoccidioides brasiliensis. It is also called paracoccidioidal granuloma. (12 Dec 1998) |
