As many as 50% of patients with thymoma have MG, and approximately 15% of patients with MG have thymoma. Pts who have a Thymoma superimposed on MG have the poor prognosis.
MG is caused by autoantibodies to postsynaptic nicotinic acetylcholine receptors (anti-AChRs) at the neuromuscular junction, causing weakness of skeletal muscles. Some patients with thymoma-associated MG have an inflammatory myopathy of striated and cardiac muscles. Cardiac myositis may cause heart failure, cardiac arrhythmia, and sudden death.
