(MedPage Today) -- Case Findings: A 23-year-old male presents with a presumed diagnosis of vanishing bone disease (Gorham's disease), a rare condition in which bone is lost in conjunction with an overgrowth of lymphatic vessels. However, the patient presents with ongoing severe pain, which is uncommon in Gorham's disease. He was treated with interferon and zoledronic acid, but discontinued these treatments because of severe side effects. What is your diagnosis?
