[Granulomatous idiopathic myositis at pediatric onset. Description of a case and a review of literature]. / Miosite granulomatosa idiopatica in età pediatrica. Descrizione di un caso e revisione della letteratura.

The authors report a case of granulomatous myositis in a child (the cases in literature begin between 13 and 72 years). Our case is peculiar because the histological report of granulomatous myositis was accompanied by an important rise in serum CPK level without any symptoms of muscular disease. The serum CPK level, for 18 months, fluctuated between 4.190 and 22.960 UI/L while no symptom occurred. The authors complete the article with a review of the literature about the granulomatous myositis.
