It is extremely rare in pre-school ages and Graves' disease is its most common cause. Because hyperthyroidism may seriously affect growth and development in this age group, it is very important to diagnose and start treatment as soon as possible. The clinical studies and data are relatively limited due to the low prevalence of the disease in all over the world as well as in Turkey. Here we report two preschool-age cases with Graves' hyperthyroidism to bring the subject to general pediatricians' attention and discuss the management of those children.
