What describes a keloid?

An inflammation of the sebaceous glands
A hair follicle that is plugged
An acute inflammatory disorder of the sweat glands
Thick scar resulting from excessive growth of fibrous tissue

The correct answer is: Thick scar resulting from excessive growth of fibrous tissue

A keloid is not an inflammation of the sebaceous glands (option A). The sebaceous glands are responsible for producing oil on our skin, but keloids are excess growths of scar tissue. A keloid is not a hair follicle that is plugged (option B). A plugged hair follicle is a symptom of acne, while a keloid is a type of scar that forms when the body tries to heal an injury. A keloid is not an acute inflammatory disorder of the sweat glands (option C). This description is more closely related to a condition called hidradenitis suppurativa, which affects the sweat glands. A keloid is correctly described as a thick scar resulting from excessive growth of fibrous tissue (option D). Keloids can form after an injury or trauma to the skin, and are more common in certain skin types. They can also continue to grow and extend beyond the boundaries of the original injury.
