Intracutaneous hematoma.
blood blister
A blood blister is a type of blister that forms when subdermal tissues and blood vessels are damaged without piercing the
skin. It consists of a pool of lymph, blood and other
bodily fluids trapped beneath the skin. If punctured, it suppurates a dark red fluid. Sometimes the fluids are cut off from the
rest of the body and dry up, leaving behind dead cell material inside the blister. It tends to have a texture like
putty. Some blood blisters can be extremely painful due to the leaked blood touching
nerves within the part of the body where the blister occurred.
Prevention
Common areas that suffer from blood blisters include the hands and feet.
