**Core Concept**
Cauliflower ear, also known as perichondritis or cartilaginous auricular hematoma, is a condition characterized by inflammation and hematoma formation over the external ear, leading to a deformed and irregular appearance resembling cauliflower. This condition occurs due to trauma or injury to the auricle, causing blood to accumulate between the cartilage and the perichondrium, leading to infection and inflammation.

**Why the Correct Answer is Right**
The correct answer involves the pathophysiology of cauliflower ear, which is primarily caused by trauma to the auricle. When the ear is injured, blood accumulates between the cartilage and the perichondrium, leading to infection and inflammation. This process can be exacerbated by bacterial infection, particularly Staphylococcus aureus, which can cause further inflammation and tissue damage.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe the pathophysiology of cauliflower ear.
**Option B:** This option is incorrect because it is a general term that does not specifically relate to the condition of cauliflower ear.
**Option C:** This option is incorrect because it refers to a different condition altogether.

**Clinical Pearl / High-Yield Fact**
Cauliflower ear can be prevented by applying pressure to the affected area immediately after injury to prevent blood from accumulating between the cartilage and the perichondrium.

**Correct Answer: C. Perichondritis.**
