What characterizes a keloid?

• A. a portion of the small intestine
• B. formation of an infarct
• C. an elevated, irregularly-shaped scar
• D. excision of the posterior arch of a vertebra

Answer: (C)

A keloid is characterized by the formation of an elevated, irregularly-shaped scar that occurs as a result of an overproduction of collagen during the healing process of the skin. Keloids can extend beyond the boundaries of the original wound and may vary in size and color. They often result from injuries, surgeries, acne scars, or even from minor skin trauma, and they sometimes lead to itching or discomfort for the individual. This excessive scar tissue formation is a fundamental aspect of keloids, distinguishing them from normal scars, which typically lie flat and do not extend beyond the original injury site. This distinctive characteristic makes option C the most accurate and relevant description of what a keloid is.
