Patterned bruise (Patterned contusion)
- A bruise that reflects the shape/design of the object causing injury
- Examples:
- Tyre marks
- Rope marks
- Belt marks
- Mechanism:
- Blunt force causes bleeding under skin
- Pattern is transferred due to pressure differences
Explanation of Other Options
A. Percolated bruise
- Blood tracks along tissue planes
- Seen away from site of injury
- No pattern reproduction
B. Imprint abrasion
- Superficial injury (abrasion) reproducing pattern
- Involves epidermal damage only, not deep bruise
- Tyre injuries usually produce deeper contusions, not just abrasions
C. Contusion
- General term for bruise
- Does not specify patterned nature
