Abstract
Case studies of five patients with neuro-myopathic syndromes secondary to bronchogenic carcinoma illustrate the variations of neurologic diseases found in this malignancy. Recognition of this syndrome may be important in the early diagnosis and treatment of bronchogenic carcinoma. The cause of neuromyopathies secondary to bronchogenic carcinoma remains obscure; however, a metabolic abnormality common to all the extrapulmonary manifestations of bronchogenic carcinoma may yet be documented.
