**Core Concept**
Hyperrophic scars are a type of raised, thickened scar tissue that develops after skin injury, often as a result of excessive collagen deposition and altered wound healing. The pathophysiology involves an imbalance between the synthesis and degradation of extracellular matrix components, leading to a buildup of collagen and other proteins.

**Why the Correct Answer is Right**
The correct answer is related to the fact that hypertrophic scars are characterized by an increased number of fibroblasts and a disorganized pattern of collagen deposition. This leads to a thickened scar that is often red, raised, and itchy. The altered wound healing process involves an imbalance between the synthesis of collagen and the degradation of the extracellular matrix, resulting in a scar that is more prominent than the original wound.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because hypertrophic scars are not typically associated with keloid formation, which is a different type of raised scar tissue that can occur in any individual, regardless of skin type.

**Option B:** Incorrect because hypertrophic scars are not typically associated with a decrease in collagen deposition, but rather an increase due to excessive fibroblast activity.

**Option C:** Incorrect because hypertrophic scars are not typically associated with an increase in skin elasticity, but rather a decrease due to the altered collagen deposition and skin texture.

**Clinical Pearl / High-Yield Fact**
A key feature of hypertrophic scars is that they often regress over time, but the rate of regression can vary greatly between individuals. It is essential to monitor the scar's progression and adjust treatment plans accordingly.

**Correct Answer: B. Increased collagen deposition is a hallmark of hypertrophic scars.**
