General Discussion. Lambert-Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder characterized by the gradual onset of muscle weakness, especially of the pelvic and thigh muscles. Approximately 60 percent of LEMS cases are associated with a small cell lung cancer (SCLC), and the onset of LEMS symptoms often precedes the detection of the cancer.
Patients with LEMS typically present with fatigue, muscle pain and stiffness. The weakness is generally more marked in the lower extremity muscles, particularly of the legs and hip-girdle. See Figure 1. Other problems include reduced reflexes, drooping of the eyelids, facial weakness and problems with swallowing.
