A Case of Myasthenia Gravis Associated with Aplastic Anemia

ABSTRACT

Myasthenia gravis is occasionally associated with other autoimmune diseases. Aplastic anemia of autoimmune type has been reported to coincide with myasthenia gravis, particularly with thymoma. A 63-year-old woman with diplopia and ptosis was diagnosed as myasthenia gravis and aplastic anemia was found incidentally through appropriate studies. She was treated with prednisolone and mestinon, and ptosis and anemia were well controlled. We report this patient as the first case of myasthenia gravis associated with aplastic anemia without thymoma in Korea.
