Definition
This section has been translated automatically.

The term purpura is used in the narrower sense as a synonym for bleeding into the skin. Skin bleeding is a clinical phenomenon in which erythrocytes leak into the dermal tissue. Skin bleeding can be acute or chronic. They are characterized by localized or disseminated, small or large spots, red, blue, blue-green or yellow-brown (diascopically unpushable) spots or palpable elevations (color tones caused by bleeding of different ages). A purpura can be triggered by a variety of causes.

A purpura can be flat (spot) or eleated (papule = palpable purpura), inflammatory ( vasculitis) or non-inflammatory (e.g. due to vasculopathy).

In a broader sense, independent diseases are also called "purpura", which are accompanied by bleeding into the skin (e.g. Purpura pigmentosa progressiva; Purpura Schönlein-Henoch).
