DefinitionThis section has been translated automatically.
The term purpura in the narrower sense refers to the seeding of small spots of blood in the skin. Skin hemorrhages (hemorrhages) are a clinical phenomenon. Purpura is characterized by localized or disseminated, small-spotted or extensive, red, blue, blue-green or yellow-brown (diascopically non-blanchable) spots or palpable elevations (shades due to bleeding of different ages). Purpura can be triggered by a variety of causes.
Purpura can be flat(spot) or elevated(papule = palpable purpura), inflammatory (vasculitis) or non-inflammatory (e.g. due to a vasculopathy).
In a broader sense, independent diseases are also referred to as "purpura", which are associated with hemorrhages in the skin (e.g. purpura pigmentosa progressiva; purpura Schönlein-Henoch).
