What condition results from the inflammation of hair follicles commonly due to infection or irritation?

• A. Folliculitis
• B. Alopecia
• C. Dermatofibroma
• D. Psoriasis

Answer: (A)

Folliculitis is the condition characterized by the inflammation of hair follicles, which can often be triggered by infections, such as bacterial or fungal pathogens, or by various irritants. This inflammation typically results in red, itchy bumps or pustules around the affected follicles, and it can occur anywhere on the body where hair grows. Recognizing this condition is important because it can lead to further complications if not addressed, including the potential for more pervasive skin infections.

Other conditions mentioned are not classified under the same mechanisms. Alopecia refers to hair loss, which is unrelated to inflammation of the follicles. Dermatofibroma is a benign skin tumor that arises from fibrous tissue, not an inflammatory response. Psoriasis is a chronic autoimmune condition characterized by scaly plaques on the skin, which is fundamentally different from folliculitis in terms of pathophysiology. Understanding these distinctions helps clarify why folliculitis is specifically associated with hair follicle inflammation.
