NIC Barber Written (Theory) ExamScientific ConceptsEasy
A barber notices a client has an abnormally large pore, often filled with a black or dark brown plug of sebum and dead skin cells. What is this skin lesion commonly known as?
- AMacule
- BComedone
- CPustule
- DPapule
Show answer & explanationAnswer & explanation
Correct answer: B. Comedone
A comedone is a common skin lesion, typically an enlarged pore filled with sebum and dead skin cells, which can be either open (blackhead) or closed (whitehead). Recognizing these lesions is fundamental for barbers to ensure client skin health and safety.
Why the other options are wrong
- A. A macule is a flat, discolored spot on the skin without elevation or depression, not a pore plug.
- C. A pustule is a small, inflamed, pus-filled lesion, different from a sebum plug.
- D. A papule is a small, solid, elevated lesion without pus, distinct from a comedone.
Comedone
A hair follicle that has become clogged with sebum and dead skin cells, forming a lesion.
- Can be open (blackhead) or closed (whitehead).
- Commonly associated with acne.
- Not inflammatory unless infected.
Memory trick: Many lesions, but the 'plugged pore' is the 'Comedone' core.
