What type of dermatitis is characterized by redness and scaling, typically around the mouth area?

1. Seborrheic dermatitis

2. Contact dermatitis

3. Perioral dermatitis

4. Acne vulgaris

The correct answer is: Perioral dermatitis

Perioral dermatitis is characterized by a distinctive presentation of redness and scaling specifically around the mouth area. It often manifests as small, red bumps or pus-filled lesions, primarily affecting the skin surrounding the mouth, although it can sometimes extend to the nose and eyes. The exact cause of perioral dermatitis isn't entirely understood, but it may be associated with the use of topical steroids, heavy facial products, or even hormonal changes. In contrast, seborrheic dermatitis typically presents as oily scaling and redness on the scalp, face, and upper body, rather than specifically around the mouth. Contact dermatitis involves localized inflammation due to an irritant or allergen but does not specifically correlate with the unique pattern seen in perioral dermatitis. Acne vulgaris, while it may cause hormonal or inflammatory lesions, occurs primarily on the face, back, and shoulders and is not limited to the area around the mouth. Thus, the defining characteristics of perioral dermatitis align perfectly with the symptoms described in the question, making it the correct choice.
