title: [Chronic recurrent multifocal osteomyelitis and tumoral calcinosis--is there an association?].
abstract: BACKGROUND
  Idiopathic tumorous calcinosis is a rare benign disease of the periarticular tissue near large joints. Deposits of hydroxyapatite in single or multiple pseudocysts lead to consecutive pain or complaints by attaching the surrounding tissues. The etiology of this disease is not definitively clear.
  
  
  METHODS
  We describe the case of an 11-year-old turkish girl with a well known chronic recurrent multifocal osteomyelitis (CRMO) and hyperphosphataemia. Furthermore, she developed a tumorous calcinosis around the left hip, which recurred after surgery, and around the ankle joint.
  
  
  CONCLUSIONS
  CRMO and tumorous calcinosis can be associated diseases. The development of tumorous calcinosis in patients with CRMO and hyperphosphataemia should be excluded.
