Abstract
This article presents a clinical case of a 24-year-old man with progressive fibrodysplasia ossificans. The progressive course of the disease leads to severe functional disorders of the musculoskeletal system, severe disability of patients and premature death, mainly at a young age. There is no way to prevent the progression of the disease. Surgical removal of ossificates only enhances the processes of ossification. A common cause of death is a pulmonary infection due to hypoventilation. In the future, there is hope for the creation of a drug that blocks the genetic mechanism that triggers the growth of extra bones.Key words: рrogressive fibrodysplasia ossificans, clinical case, fibromyozitis, fibrosarcoma, treatment fibrodysplasia, clinical case.
