INTRODUCTION

Acne may be defined broadly as any condition that begins with the microcomedone. This therefore encompasses acne vulgaris, neonatal and infantile acne, and acne fulminans. However, rosacea and its variants do not fit this definition: even though rosacea superficially appears acneiform, having erythematous papules and pustules, and occurring mainly on the face, no comedones are seen. The follicular occlusion triad represents a group of diseases—hidradenitis suppurativa, acne conglobata, and dissecting cellulitis—that often occur together and that result from occlusion of the follicle.
