Abstract Background:Severe up to life-threatening neuropathy has beenobserved in patients with hereditary neuropathies receiving vincristine. Case report:A 52-year-old female painter suffering fromhigh-grade non-Hodgkin's lymphoma (stage IVB) was treated with a total of 4mg of vincristine during two courses of CHOP chemotherapy (cyclophosphamide,vincristine, adriamycin, prednisone). At onset of treatment no neurologicalproblems were reported. There was good lymphoma response to chemotherapy. Atthe same time, however, the patient gradually developed dysphagia, dysarthria,muscular weakness of both lower and upper extremities, areflexia, paraesthesiaof the fingertips and bilateral sensory impairment of feet and lower legs.These symptoms continually worsened over a period of seven weeks until she wasunable to walk or to perform her work. Electrophysiological studies showedperipheral axonal and demyelinative sensorimotor neuropathy in correlation tohistological findings. Molecular analysis revealed 17p11.2 duplication typicalfor Charcot–Marie–Tooth disease IA. While continuing chemotherapywithout the use of vincristine the patient's neurologic symptoms slowlyrecovered within six months. Conclusion:Prior to administration of vincristine family andpatient history as well as physical examination should be performed carefullyto look for underlying hereditary neuropathy. For those patients with aclinical history or symptoms suggestive for CMT nerve conduction velocitystudies and on an individual base even molecular genetic analysis areneccessary to prevent serious neurologic complications.
