ICD-10 online (WHO version 2019) |
Under purpura refers to capillary bleeding in the skin , under the skin ( subcutaneous ), or the mucous membranes ( hemorrhage ). The individual bleeding can be punctiform ( petechiae ), more rarely also in stripes ( vibex ), small areas ( sugillation ) or extensive ( ecchymosis ).
The cause of a purpura is a tendency to bleed ( hemorrhagic diathesis , "blood leakage") through, for example:
- Blood vessel disorders ( vasculitis )
- Damage to the blood platelets ( thrombocytopathy )
- toxic-allergic coagulation disorders (for example due to drugs or infection )
- Blood congestion ( stasis )
- Radiation sickness
Purpura mostly occurs on the lower extremities. The blood stains are initially red, later they change color from brown and green to yellow due to the breakdown of hemoglobin .
In contrast to an erythema , the spots do not disappear when pressure is applied to the relevant area.
Special forms
- Henoch-Schönlein purpura ( purpura anaphylactoides , anaphylactoid purpura )
- Thrombotic thrombocytopenic purpura (Moschcowitz syndrome)
- Anular purpura teleangiectodes (Majocchi syndrome)
- Idiopathic thrombocytopenic purpura (idiopathic thrombocytopenia, Werlhof)
- Autoerythrocytic Purpura ( Gardner Diamond Syndrome )
- Purpura fulminans (protein C deficiency)
