ABSTRACT
Acne is one of the most common diseases affecting the pediatric population and
a frequent chief complaint for office visits for both pediatricians and derma-
tologists. While it is primarily a skin disorder of adolescents, acne is also a less
studied, but equally important, condition faced by children who have not yet
reached puberty. This special group of acne patients may be categorized into the
following four clinical entities on the basis of the time of onset and clinical
features: neonatal, infantile, mid-childhood, and preadolescent acne (Table 8.1.1).
The clinical presentation, pathophysiology, differential diagnosis, workup, and
treatment of each of these types of acne differ to varying degrees and will
therefore be addressed on an individual basis.
