purpura
Subcutaneous bleeding spots
Purpura is a medical condition marked by purple or reddish-brown spots on the skin, caused by bleeding beneath the surface.
The discoloration results from broken blood vessels, often indicating a clotting disorder or blood vessel inflammation.
Unlike a bruise from injury, purpura typically appears without trauma: The doctor noticed purpura on the patient's legs and ordered blood tests.
