Stellate Laceration

Definition

A star-shaped tearing of the skin at the entry wound, produced by the gas pressure at contact range when the wound overlies a rigid bony surface (typically the skull). Caused by the rebounding gas pressure, not the bullet.

Shape
Star-shaped tearing of the skin at the entry wound
Cause
Rebounding gas pressure at contact range, not the bullet
Requires
A rigid bony surface underlying the wound, typically the skull

Common questions

Why is a stellate laceration mostly seen on the head rather than the abdomen at contact range?+

The tearing depends on gas pressure rebounding off a rigid surface directly beneath the skin, and the skull provides that rigid backing, while soft tissue over the abdomen absorbs and disperses the gas pressure instead of reflecting it back into the skin.

Could a stellate laceration be mistaken for an exit wound?+

Yes, the irregular star-shaped tearing can superficially resemble exit wound characteristics, which is why examiners correlate it with soot, muzzle imprint, and the wound track rather than relying on shape alone to call it an entrance.
