Jerry has a condition that most commonly occurs on which body surface (folliculitis)?

• A. Neck & scalp
• B. Upper arms
• C. Chest & abdomen
• D. Legs

Answer: (A)

Folliculitis is inflammation or infection of hair follicles, often due to bacteria such as Staphylococcus and exacerbated by friction, moisture, or occlusion. It tends to appear where hair is plentiful and the skin is repeatedly irritated or sweaty. The neck and scalp fit this pattern best because they have a dense concentration of hair follicles and are areas where shaving, collars, hats, and sweating can repeatedly irritate follicles, making infection more likely. Clinically, you’d see small red papules or pustules centered on hair follicles, sometimes with crusting. Other areas like the arms, chest/abdomen, or legs can be involved but are less commonly affected compared with the neck and scalp.
