© 2019 Multimed Inc. Charcot–Marie–Tooth (cmt) disease is the most common form of inherited neuropathy. Core features include peripheral neuropathy and secondary axonal degeneration, with a noted distal predominance of limb-muscle wasting, weakness, and sensory loss. Given the significant prevalence of cmt, superimposed neoplastic disease can be encountered within this patient population. Malignancies that are treated with vincristine (a microtubule-targeting agent), even at low doses as part of standard treatment, pose a significant challenge for patients with cmt. Here, we present the case of a child with cmt who was successfully treated for medulloblastoma without vincristine, a standard drug used for treatment of that disease, to avoid the risk of severe debilitating neuropathy. This report is the first of a patient successfully treated for medulloblastoma without vincristine.
