It can affect the entire skeleton. Symptoms may include bone pain, swelling, and fractures. Diagnosis relies mainly on imaging and histology. Treatment may include bisphosphonates (osteoclast inhibitors), sirolimus (mTOR (mechanistic Target Of Rapamycin) inhibitor), radiotherapy, and surgery. The prognosis is uncertain and depending on the location and severity of the lesions, the condition may be life-threatening. This article reviews the current knowledge about this disease and illustrates it with a clinical case.
