Step-by-step explanation:
A localized soft tissue injury characterized by swelling and bruising is called a/an contusion.
A contusion, also known as a bruise, occurs when blood vessels beneath the skin rupture due to trauma. The ruptured blood vessels leak blood into the surrounding tissues, resulting in swelling and discoloration. Unlike sprains and strains, which involve ligaments and muscles, a contusion primarily affects the soft tissues.
For example, if someone bumps their leg against a table and develops a swollen, bruised area, that would be considered a contusion.
