DefinitionThis section has been translated automatically.
The term purpura is used in a narrow sense synonymously for bleeding into the skin. Skin hemorrhages are a clinical phenomenon in which there are leaks of erythrocytes into the dermal tissue. Skin hemorrhages can be acute or chronic. They are characterized by localized or disseminated, small-spotted or patchy, red, blue, blue-green, or yellow-brown (diascopically not pushable away) spots or palpable elevations (hues due to hemorrhages of different ages). Purpura can be triggered by a variety of causes.
Purpura may be flat (spot) or elevated (papule = palpable purpura), inflammatory (vasculitis) or noninflammatory (e.g., due to vasculopathy).
