| hyperglobulinemic purpura | A condition characterised by proliferation of cells resembling lymphocytes or plasma cells in the bone marrow, anaemia, increased sedimentation rate and hyperglobulinaemia. Physical findings include mucosal bleeding, skin purpura and enlargement of the lymph nodes, liver and spleen. (27 Sep 1997) |

| nonthrombocytopenic purpura | The eruption of petechiae or larger ecchymoses, usually unaccompanied by constitutional symptoms and not associated with systemic illness. Synonym: nonthrombocytopenic purpura. (05 Mar 2000) |
| idiopathic thrombocytopenia purpura | <haematology> A rare autoimmune disorder characterised by an acute shortage of platelets with resultant bruising and spontaneous bleeding. The platelet count becomes exceedingly low and spontaneous bleeding from the gums, gastrointestinal tract and nose can be seen. Physical examination may demonstrate enlargement of the spleen. A typical rash occurs to do microscopic haemorrhage of small blood vessels in the skin. Platelet counts under 10,000 can lead to spontaneous haemorrhage into the brain causing death. Treatment with corticosteroids is generally effective. Surgical removal of the spleen (splenectomy) is reserved for some patients. Anti-platelet antibodies are detectable in some cases. It may present in either an acute or a chronic form. Acronym: ITP (20 Sep 2002) |

| immune thrombocytopenic purpura | <haematology> A low number of platelets in the blood, which is common in people with HIV, but often resolves as immune deficiency worsens. HIV-related ITP usually does not have serious consequences. Its cause has not been definitely determined. Treatment with AZT frequently alleviates the condition. (09 Oct 1997) |
| thrombocytopenia purpura | <haematology> In severe thrombocytopenia, bleeding into skin leads to small petechial haemorrhages. Primary thrombocytopenia purpura is of unknown cause but results from an autoimmune mechanism that causes platelet destruction. Secondary thrombocytopenic purpura may result from drug-induced type II hypersensitivity in which platelets coated with antibody to the drug (which is acting as a hapten) are destroyed in a complement mediated reaction. It can also follow a viral upper respiratory infection and may be seen in association with lupus. (15 Oct 1997) |

| thrombopenic purpura | idiopathic thrombocytopenia purpura |
| thrombotic thrombocytopenic purpura | A rapidly fatal or occasionally protracted disease with varied symptoms in addition to purpura, including signs of central nervous system involvement, due to formation of fibrin or platelet thrombi in arterioles and capillaries in many organs. Synonym: Moschcowitz' disease. (05 Mar 2000) |
| equine nonthrombocytopenic purpura | <veterinary> An immune-mediated vasculitis of horses due to immune complex deposition, characteristically as a sequela of strangles. (05 Mar 2000) |
| factitious purpura | Self-induced, often painful, ecchymoses. (05 Mar 2000) |
| fibrinolytic purpura | Purpura in which the bleeding is associated with rapid fibrinolysis of the clot. (05 Mar 2000) |
| articular vascular circle | An anastomosis of vessels encircling a joint. See: articular vascular network. Synonym: circulus articularis vasculosus. (05 Mar 2000) |
| articular vascular network | A vascular rete in the neighborhood of a joint, where such arrangements are common, enabling a collateral circulation by which blood will be supplied distal to the joint regardless of compromises resulting from joint position. Synonym: circulus articularis vasculosus, rete vasculosum articulare, articular network. (05 Mar 2000) |
| articular vascular network of elbow | Vascular networks in the region of the elbow, composed of anastomoses between branches of the radial and middle collateral, superior and inferior ulnar collateral, radial recurrent, interosseous recurrent, and recurrent ulnar arteries. Synonym: rete articulare cubiti. (05 Mar 2000) |
