[Lambert-Eaton myasthenia syndrome--review with case report]

The pathogenetic and therapeutic concepts in Lambert-Eaton Myasthenic Syndrome (=LEMS) are changing. The disease has been proved to be an autoimmune reaction to voltage-dependent calcium channels of the presynaptic membrane at the neuromuscular junction. As pointed out in a case report, autonomic dysfunction can be an early sign and symptom of LEMS. The update review of the literature deals with the diagnosis, aetiology and therapy of the often but not exclusively paraneoplastic induced disease.
