Continuous muscle fiber activity, peripheral neuropathy, and thymoma.
Two patients, one of them with myasthenia gravis, presented symptoms of continuous muscle fiber activity syndrome before discovery of a thymoma. Peripheral neuropathy was present in both patients, with axonal and demyelinating lesions in sural nerve biopsy. The syndrome remained unchanged or worse after thymectomy. Both patients died of associated complications.
