Study Notes
Hypertrophic Scarring Characteristics
- The defining characteristic of a hypertrophic scar is excessive collagen production and deposition, leading to a raised, thick, and red scar.
Causes of Hypertrophic Scarring
- The primary cause of hypertrophic scarring is prolonged inflammation during the wound healing process.
Collagen Fiber Alignment
- In a hypertrophic scar, collagen fiber alignment is characterized by a whorl-like or irregular pattern, differing from the usual linear pattern found in normal scars.
Onset of Hypertrophic Scarring
- Hypertrophic scars typically begin to appear 3-6 weeks post-wound healing and may take several months to a year or more to mature.
Scar Maturation Time
- The average time for scar maturation in hypertrophic scarring is around 12-18 months, although this process can take up to 2 years or more in some cases.

Description
Test your knowledge about hypertrophic scars, which are an overgrowth of dermal constituents within the boundaries of a wound. Learn about the imbalance of matrix degradation and collagen biosynthesis that leads to excess collagen accumulation in the wound.
