Lambert‐eation myasthenic syndrome

This review of the Lambert-Eaton myasthenic syndrome (LEMS) emphasizes electrodiagnosis and includes a case report. A 50-year-old woman had become progressively weaker over 1.5 years. The suspected diagnosis was confirmed by the clinical electrophysiological findings and was made 6 months before the patient's oat-cell carcinoma was found. After treating with local radiation and chemotherapy, the myasthenic syndrome went into remission as the pulmonary lesion resolved.
