title: [Lambert-Eaton myasthenic syndrome--a rare manifestation of paraneoplastic syndrome in ovarian cancer--case report].
abstract: BACKGROUND
  Paraneoplastic neurological syndromes are rare non-metastatic complications of cancer that have an immune-mediated etiology. The Lambert-Eaton myasthenic syndrome (LEMS) is a neuromuscular disorder, often associated with small cell lung carcinoma (SCLC), which is characterized by reduced quantal release of acetylcholine from the motor nerve terminals. LAMBERT-EATON MYASTHENIC SYNDROME: The Lambert-Eaton Myasthenic Syndrome (LEMS) is characterized by proximal muscle weakness initially affecting gait, autonomic symptoms (dry mouth, constipation, erectile failure) and augmentation of strength during initial voluntary activation. Symptomatic treatment of the junctional disorder is based on cholinergic drugs, immunosuppression, immunomodulation and physical therapy useful in case of unsuccessful antineoplastic therapy.
  
  
  METHODS
  A rare case of ovarian cancer with Eaton-Lambert syndrome is reported. A 50-year-old woman was admitted to the gynecologic department, complaining of weakness and pain in her arms and shoulders. Physical therapy resulted in partial improvement. Treatment of paraneoplastic syndrome markedly improves the quality of life of cancer patients. Patients presenting with this syndrome should undergo a careful evaluation for the presence of an occult malignancy.
