Old syndrome-new approach: Mauriac syndrome treated with continuous insulin delivery.

Mauriac syndrome has rarely been reported in children and adolescents with a poorly controlled diabetes mellitus type 1. However, it still occurs despite the worldwide improvements of metabolic control. The risks have not been elucidated. We present a 13.5-year-old boy with a typical clinical presentation of Mauriac syndrome consisting of growth delay, cushingoid appearance, hepatomegaly, and delayed puberty. A stepwise correction of glycemic control was introduced using continuous insulin delivery. All symptoms improved during the 2.5-year follow-up. No retinopathy occurred. This patient with Mauriac syndrome followed with continuous glucose monitoring and treated with continuous insulin delivery, resulting in no retinopathy after 2.5 years of follow-up. We suggest that this approach should be recommended in patients with Mauriac syndrome.
