DefinitionThis section has been translated automatically.
In a narrower sense, the term purpura refers to an exanthema with petechial skin bleeding (hemorrhages).
Skin hemorrhages (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 caused by a variety of causes.
A purpura may be flat(spot) or elevated(papule = palpable purpura), inflammatory (vasculitis) or noninflammatory (e.g., due to a vasculopathy).
In a broader sense, independent diseases are also called "purpura", which are associated with hemorrhages in the skin (e.g., purpura pigmentosa progressiva; purpura Schönlein-Henoch).
