Study Notes
Distinguishing Features of Hypertrophic Scars and Keloids
- A distinguishing feature of hypertrophic scars is that they remain within the boundaries of the original wound area.
Keloid Occurrence
- Keloids occur more frequently in individuals with darker skin tones, particularly in African, Asian, and Hispanic populations.
- Keloids are also more common in areas of high skin tension, such as the chest, shoulders, and earlobes.
Distinguishing Features of Keloids
- A distinguishing feature of keloids is that they extend beyond the original wound area, forming raised, nodular, or ridged lesions.
Shared Characteristics
- One characteristic associated with both hypertrophic scars and keloids is the excessive production of collagen during the wound healing process.
