Feature of ruptured skin caused by excessive heat: AIIMS 10
**Core Concept**
Burns caused by excessive heat can be classified based on their depth, and understanding the characteristics of each type is crucial for proper management. The depth of a burn is determined by the extent of damage to the skin layers and underlying tissues.
**Why the Correct Answer is Right**
In the case of a burn caused by excessive heat, the skin undergoes coagulative necrosis, leading to the formation of a characteristic eschar. This eschar is a result of the denaturation of proteins in the skin, causing it to become leathery and dry. The eschar can separate from the underlying tissue, leading to the formation of a blister or a crater.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe the characteristic feature of a burn caused by excessive heat.
**Option B:** This option is incorrect because it describes a feature of a burn caused by cold temperatures, not excessive heat.
**Option C:** This option is incorrect because it describes a feature of a burn caused by electrical injuries, not excessive heat.
**Clinical Pearl / High-Yield Fact**
A key clinical feature of a burn caused by excessive heat is the formation of an eschar, which can separate from the underlying tissue and lead to the formation of a blister or a crater. This can lead to infection and delayed healing if not properly managed.
**Correct Answer: D. Eschar.**
