What is the distinctive feathering marking seen on lightning strike victims?

• A. Lichtenberg Figure
• B. Froin Sign
• C. Beau's Lines
• D. Muehrcke's Nails

Answer: (A)

Lichtenberg figures are the distinctive fern-like, feathering skin markings seen on lightning strike victims. They arise from the rapid electrical discharge causing superficial capillary rupture in the skin, producing arborescent, fractal patterns that look like fine leaves or feathers. These markings are highly characteristic of lightning injury and typically appear soon after the strike, often fading over hours to days. They are not typical burns and reflect the physical effect of the electrical discharge rather than heat damage. The other terms describe findings in completely different contexts (nail changes or signs in other medical conditions), so they don’t fit as explanations for the skin feathering pattern seen with lightning exposure.
