Recurrence of thymoma and myasthenia gravis after 19 years. A case report.
Myasthenia gravis developed in a 51-year-old woman in 1956; she was found to have a thymoma. Complete remission of the myasthenia gravis occurred within 18 months of thymomectomy. In 1975, myasthenia gravis recurred in association with recurrence of the thymoma. Remission of the myasthenic state once more followed the thymomectomy. The asymptomatic period of 18 years is, to our knowledge, the longest reported interval for recurrence of a thymoma-associated myasthenia gravis; 15 years is the longest reported interval for recurrence of a thymoma.
