| cutaneous test | A method for determining induced sensitivity (allergy) by applying an antigen (allergen) to, or inoculating it into, the skin; induced sensitivity (allergy) to the specific antigen is indicated by an inflammatory reaction of one of two general kinds: 1) immediate, appears in minutes to an hour or so and in general is dependent upon circulating immunoglobulins (antibodies); 2) delayed, appears in 12 to 48 hours and is not dependent upon these soluble substances but upon cellular response and infiltration. Synonym: cutaneous test, cutireaction test, skin reaction. (05 Mar 2000) |

| cutaneous tuberculosis | Pathologic lesions of the skin caused by Mycobacterium tuberculosis. Synonym: dermal tuberculosis, tuberculosis cutis. (05 Mar 2000) |
| cutaneous ureterostomy | A stoma constructed of ureter at skin level for drainage of urine. This may be an end stoma or a loop stoma. Usually performed because of distal obstruction. Synonym: cutaneous loop ureterostomy. (05 Mar 2000) |
| cutaneous vasculitis | An acute form of vasculitis which may affect the skin only, but also may involve other organs, with a polymorphonuclear infiltrate in the walls of and surrounding small (dermal) vessels. Nuclear fragments are formed by karyorrhexis of the neutrophils. See: leukocytoclastic vasculitis. Synonym: allergic angiitis, hypersensitivity vasculitis. (05 Mar 2000) |
| cutaneous vein | <anatomy, vein> One of a number of veins that course in the subcutaneous tissue and empty into deep veins; they form prominent systems of vessels in the limbs and are usually not accompanied by arteries. Synonym: vena cutanea, cutaneous vein. (05 Mar 2000) |
| syphilis, cutaneous | Cutaneous lesions arising from infection with treponema pallidum. In the primary stage, 18-21 days following infection, one or more chancres appear. If untreated, the subsequent stages of the disease appear as syphilids. These eruptions are superficial, nondestructive, exanthematic, transient, macular roseolas that may later be maculopapular or papular polymorphous or scaly, pustular, pigmented eruptions.(arnold, odom, and james, andrew's diseases of the skin, 8th ed, p409) (12 Dec 1998) |
| diffuse cutaneous leishmaniasis | Leishmaniasis caused by several New and Old World species and strains of Leishmania (L. Mexicana amazonensis, L. M. Pifanoi, possibly L. M. Garnhami and L. M. Venezuelensis; in Ethiopia, L. Aethiopica, and unidentified leishmanial agents in Namibia and Tanzania). The condition is associated with a suppressed cell-mediated immune response, so that the non-ulcerating, non-necrotizing cutaneous lesions can spread widely over the body; great numbers of parasite-filled macrophages are found in the dermal lesions. Healing does not appear to occur unless an acquired cellular hypersensitivity can develop. Synonym: anergic leishmaniasis, diffuse leishmaniasis, disseminated cutaneous leishmaniasis, leishmaniasis tegumentaria diffusa, pseudolepromatous leishmaniasis. (05 Mar 2000) |
| diffuse cutaneous mastocytosis | A benign process consisting of focal cutaneous infiltrates composed of mast cells; lesions are flat or slightly elevated, form wheals and itch when stroked; bone lesions may occur. Synonym: urticaria pigmentosa. (05 Mar 2000) |
| disseminated cutaneous gangrene | A bullous or pustular eruption, of uncertain origin, followed by necrotic ulcers or extensive gangrene in children under 2 years of age; if untreated, death may result from haematogenous infection, such as liver abscess. Synonym: disseminated cutaneous gangrene, ecthyma gangrenosum, pemphigus gangrenosus, rupia escharotica. (05 Mar 2000) |
| disseminated cutaneous leishmaniasis | Leishmaniasis caused by several New and Old World species and strains of Leishmania (L. Mexicana amazonensis, L. M. Pifanoi, possibly L. M. Garnhami and L. M. Venezuelensis; in Ethiopia, L. Aethiopica, and unidentified leishmanial agents in Namibia and Tanzania). The condition is associated with a suppressed cell-mediated immune response, so that the non-ulcerating, non-necrotizing cutaneous lesions can spread widely over the body; great numbers of parasite-filled macrophages are found in the dermal lesions. Healing does not appear to occur unless an acquired cellular hypersensitivity can develop. Synonym: anergic leishmaniasis, diffuse leishmaniasis, disseminated cutaneous leishmaniasis, leishmaniasis tegumentaria diffusa, pseudolepromatous leishmaniasis. (05 Mar 2000) |
| dry cutaneous leishmaniasis | A form of Old World cutaneous leishmaniasis, usually with a prolonged incubation period and confined to urban areas. Synonym: chronic cutaneous leishmaniasis, dry cutaneous leishmaniasis, urban cutaneous leishmaniasis. (05 Mar 2000) |
| tuberculosis, cutaneous | Tuberculosis of the skin. It includes scrofuloderma and tuberculid, but not lupus vulgaris, which is lupus. (12 Dec 1998) |
| zoonotic cutaneous leishmaniasis | A form of cutaneous leishmaniasis characterised by rural distribution of human cases near infected rodents, particularly communal ground squirrels; characterised by acute rapidly developing dermal lesions that become severely inflamed, with moist necrotizing sores or ulcers that heal in two to eight months after a two to four month incubation period; among nonimmune immigrants, multiple lesions may develop, which heal more slowly and leave disabling or disfiguring scars. A strong delayed hypersensitivity and involvement of immune complexes play a role in necrosis, which is part of the healing process and of the strong specific immunity that follows. Synonym: acute cutaneous leishmaniasis, rural cutaneous leishmaniasis, wet cutaneous leishmaniasis. (05 Mar 2000) |
| urban cutaneous leishmaniasis | A form of Old World cutaneous leishmaniasis, usually with a prolonged incubation period and confined to urban areas. Synonym: chronic cutaneous leishmaniasis, dry cutaneous leishmaniasis, urban cutaneous leishmaniasis. (05 Mar 2000) |
| leishmaniasis, cutaneous | An endemic disease that is characterised by the development of single or multiple localised lesions on exposed areas of skin that typically ulcerate. The disease has been divided into old and new world forms. Old world leishmaniasis is separated into three distinct types according to epidemiology and clinical manifestations and is caused by species of the l. Tropica and l. Aethiopica complexes as well as by species of the l. Major genus. New world leishmaniasis, also called american leishmaniasis, occurs in south and central america and is caused by species of the l. Mexicana or l. Braziliensis complexes. (12 Dec 1998) |
