Morel-Lavallee lesion leave lesion is seen in
**Core Concept**
A Morel-Lavallee lesion is a type of closed degloving injury characterized by the formation of a cavity between the skin and subcutaneous tissue, often resulting from severe blunt trauma. This lesion is caused by the separation of the skin and subcutaneous tissue from the underlying fascia, leading to a fluid-filled cavity.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of Morel-Lavallee lesion, which involves the disruption of the fascial layer and the subsequent formation of a fluid-filled cavity. The lesion typically occurs in areas where the skin and subcutaneous tissue are tightly adherent to the underlying fascia, such as the thigh or buttock. The fluid accumulation in the cavity is due to the disruption of lymphatic and venous drainage.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect as Morel-Lavallee lesion is not typically associated with open wounds or lacerations.
* **Option B:** This option is incorrect as Morel-Lavallee lesion is not a type of infection or abscess.
* **Option C:** This option is incorrect as Morel-Lavallee lesion is not a type of skin cancer or tumor.
**Clinical Pearl / High-Yield Fact**
Morel-Lavallee lesion is a type of closed degloving injury that can be easily missed on initial presentation, but it is essential to diagnose and treat promptly to prevent complications such as infection and chronic fluid collection.
**Correct Answer: C. A type of closed degloving injury.**
