The diagnostic value of café-au-lait macules.

Abstract

Single café-au-lait macules (CALMs) are common in the pediatric population and in most children represent a normal finding. It is important to recognize whether the presence of multiple CALMs in a particular patient is normal or indicates an association with a multisystem disorder. This article addresses issues concerning the prevalence, genetics, and natural history of CALMs in the general population and reviews disorders in which CALMs are present as a characteristic trait.
