What type of skin condition involves superficial wounds with no underlying tissue damage?

The correct answer is abrasion, which refers to a type of skin injury characterized by the removal of the outer layer of skin without causing damage to the underlying tissues. This condition typically results from friction against a rough surface, such as when a person falls and scrapes their skin on the ground. Since an abrasion only affects the superficial layers of the skin, it usually heals on its own and can present with mild pain, redness, and sometimes minor bleeding, but there is no significant trauma to deeper tissues.

In contrast, a contusion refers to a bruise caused by blunt force trauma that damages the small blood vessels under the skin, leading to bleeding and discoloration but leaving the skin intact. Lacerations involve deeper cuts that break through the skin and potentially damage underlying tissues, which can require stitches for proper healing. Pustules are small, raised lesions on the skin that contain pus, often associated with infections or certain skin conditions, and do not directly relate to the type of wound implied in the question.
