Thymoma with Lambert-Eaton myasthenic syndrome.

We describe a rare case of thymoma with Lambert-Eaton myasthenic syndrome. A 62-year-old woman reporting weakness in her legs and arms was found to have an anterior mediastinal mass on computed tomography. Electromyography showed incremental response to repeated stimulations, and thymoma with Lambert-Eaton myasthenic syndrome was diagnosed. The patient was successfully treated with video-assisted thoracoscopic extended thymectomy.
