Acne, Perioral Dermatitis, Rosacea, and Hidradenitis Suppurativa.

Acne and related dermatoses encompass a spectrum of conditions that present at different stages in life and are commonly seen in the primary care setting. The primary care clinician should be familiar with the presentation, diagnosis, differentiation and management of acne, perioral dermatitis, rosacea, and hidradenitis suppurativa. Factors such as patient age, genetics, hormones, infections, occupation, habits, cosmetics, and medications may impact the presentation of acne-like eruptions. Clinical presentation offers clues to the physician that help differentiate acneiform conditions like perioral dermatitis, rosacea, and hidradenitis suppurativa. These conditions do not respond to standard acne therapy and require different treatment strategies.
