title: [Symptoms of severe calciphylaxis in a girl with X-linked hypophosphataemia].
abstract: X-linked hypophosphataemia (XLH) is the most common form of hereditary rickets. We present a case report of a girl who was diagnosed with XLH. She was treated with activated vitamin D and phosphate and received several correctives surgical procedures. After a knee surgery, complicated with osteomyelitis, she presented with symptoms of severe calciphylaxis with calcification of several organ systems. Medical therapy was paused and systemic inflammation was treated with steroids and loop diuretics. This case report underlines the necessity of careful dosage of vitamin D and pausing of medical therapy after surgical procedures in patients with XLH.
