Myositis ossificans progressiva, a rare autosomal dominant disorder, is characterized by progressive heterotopic ossification of muscle and connective tissue associated with pain and disability.
I have experienced a 15-year-old woman with multiple contracture and deformity in both lower extremities. Clinical features and laboratory findings including electrodiagnostic findings were compatible with myositis ossificans progressiva. I report this case with the review of literature.
