Welt (bruise)

A welt is a bloodshot stripe on the skin. They are haematoma, a special form of a bruise.
Welts occur when blunt force is applied to the body with elongated objects without sharp edges. Like other haematomas, welts change their colors as they heal, which usually takes 2 to 4 weeks. The colors include purplish black, reddish blue, brown or yellowish green. That makes it possible to determine their approximate age.[1]
A special form of welts—when the impact tool is not flat—are double welts. They occur after blows with stick-like, long objects, such as a cane for caning, a riding crop or a garden hose. The energy of the striking tool hitting the skin forces the tissue fluid or tissue matrix to the outside of the instrument. This leaves a rather anaemic, brighter area of skin, so the area of impact of the striking tool on the skin is usually free of injury.[2] However, capillary vessels located under the skin at the edges of the impacting object rupture, resulting in two parallel, striated skin lacerations. Such double straps in a child indicate abuse and require clarification.[3][4][5]
