What type of bruise has purple lines going through it?

A bruise with purple lines through it may indicate a type of bruise known as a "linear bruise" or "patterned bruise," which can occur when a blunt object strikes the skin in a specific manner. The purple lines may represent areas where blood vessels have ruptured along the lines of impact. It is important to monitor such bruises, as they could suggest more serious underlying injuries, especially if accompanied by significant pain or swelling. If there are concerns, consulting a healthcare professional is advisable.
