Purpura

Purpura describes any red or purple discoloration on the skin that does not become paler when pressure is applied to it.  This indicates active bleeding beneath the skin.  The most common cause is vasculitis but can also be caused by scurvy, typhus, lack of platelets, and meningitis.  It often appears together with DIC.
In the House M.D. - Critical Cases episode "Station Agent", the patient suffers purpura from exposure to levamisole used with cocaine.
