Tattooing around the entry wound is seen in –
**Core Concept**
Tattooing around the entry wound is a sign of gunpowder deposition, which is a consequence of the high-pressure gases released during a gunshot. The gunpowder particles are deposited onto the skin surface, creating a pattern of tattooing around the entry wound.
**Why the Correct Answer is Right**
The high-pressure gases from the gunshot create a shockwave that propels the gunpowder particles out of the barrel and onto the skin surface. The particles are then embedded into the skin, creating a pattern of tattooing around the entry wound. This phenomenon is often seen in gunshot injuries and can be a useful diagnostic clue for forensic pathologists.
**Why Each Wrong Option is Incorrect**
* **Option A:** Tattooing is not typically seen in stabbings, as the mechanism of injury does not involve the high-pressure gases and gunpowder particles.
* **Option B:** Gunshot residue (GSR) is a different concept from tattooing, and while GSR can be seen on the skin surface, it is not the same as tattooing around the entry wound.
* **Option C:** While the entry wound itself may be affected by the gunshot, tattooing is a distinct sign that occurs due to the deposition of gunpowder particles onto the skin surface.
**Clinical Pearl / High-Yield Fact**
Tattooing around the entry wound is a classic sign of a gunshot injury, and its presence can help differentiate gunshot wounds from other types of trauma.
**Correct Answer: D. Gunshot wound.**
