## **Core Concept**
Filigree burns, also known as "filigree" or " lace-like" burns, are a characteristic type of injury associated with electrical burns. These burns result from the passage of electrical current through the body, causing damage to tissues.

## **Why the Correct Answer is Right**
The correct answer, **C. Electrical burn**, is right because filigree burns are specifically associated with electrical injuries. When an electrical current passes through the body, it can cause both external and internal damage. The external damage may appear as a small entry and exit wound, but internally, the current can cause extensive damage to muscles, nerves, and other tissues. The characteristic filigree or lace-like appearance is due to the coagulative necrosis of tissues and the formation of eschar, which can create a pattern resembling filigree.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Thermal burns are caused by direct heat application and do not typically present with a filigree pattern. They can result from flames, scalds, or contact with hot surfaces.
- **Option B:** Chemical burns result from exposure to corrosive substances and can cause a wide range of tissue damage, depending on the chemical involved. However, they do not characteristically present with filigree burns.
- **Option D:** Radiation burns occur due to exposure to ionizing or non-ionizing radiation. While they can cause severe tissue damage, they are not associated with the characteristic filigree pattern seen in electrical burns.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that electrical burns can have a deceptively small external wound but can cause extensive internal damage. The internal damage is often more severe than what is apparent on the skin surface. This makes it crucial to assess patients with electrical burns thoroughly for potential internal injuries.

## **Correct Answer:** . Electrical burn
