Which term describes inflammation of the hair follicles?

• A. Dermatitis
• B. Folliculitis
• C. Eczema
• D. Acne Vulgaris

Answer: (B)

Folliculitis is the term for inflammation of hair follicles. It presents as small red bumps or pustules centered on each follicle, often with itching or tenderness. This condition is commonly caused by infection of the follicles, most frequently by bacteria such as Staphylococcus, but can also be due to fungi or irritation from shaving, friction, or occlusion. This is distinct from dermatitis, which refers to inflammation of the skin in general rather than being centered on hair follicles. Eczema is a type of dermatitis characterized by itchy, red, scaly patches. Acne vulgaris, on the other hand, involves clogged pores and inflammatory lesions around the pilosebaceous units rather than a primary follicle-centered inflammation. So, the term that specifically describes inflammation of the hair follicles is folliculitis.
