A closed comedone is another name for which skin lesion?

• A. Blackhead
• B. Vesicle
• C. Whitehead
• D. Open comedone

Answer: (C)

A closed comedone is a whitehead. Comedones form when a hair follicle’s pore is clogged with sebum and keratin. If the pore remains closed, the plug stays beneath the surface, creating a small, flesh-colored or white bump—called a closed comedone or whitehead. If the pore opens to the surface, the plug is exposed to air and darkens, forming an open comedone, or blackhead. A vesicle is a fluid-filled blister and is not a comedone, so it doesn’t fit this description.
