Baboon syndrome in childhood: easy to avoid, easy to diagnose, but the problem continues.

Baboon syndrome was first described as a particular type of systemic contact dermatitis, characterized by an exanthem with involvement of the buttocks and flexures. In children, it is an important entity to take into account for the differential diagnosis of viral exanthem. A large number of allergens have been implicated, although inhalation of mercury vapor is a common trigger. We present the findings in 14 patients younger than 14 years with baboon syndrome. We also look at the frequency in children and the most common causes and triggers in our area.
