Chordoma is a slow-growing neoplasm arising from remnants of the embryonic notochord. Surgery is recognized as the gold standard approach, however gross total resection is rarely possible for this reason most patients undergo subtotal resection or biopsy followed by radiotherapy. Myasthenia gravis (MG) is neuromuscular autoimmune disorder .The feasibility and safety of radiotherapy and especially of proton therapy (PT) in patients affected by MG has never been adequately documented. We report the case of a patient with lumbar chordoma who was diagnosed of MG just at the beginning of PT.
