[Association of renal carcinoma with neuromyotonia and involvement of inferior motor neuron].
Acquired neuromyotonia is defined as continuous muscle activity originated in peripheral nerve due to alterations of the motor axon membrane. It has been considered a paraneoplastic syndrome in patients with neoplasms of the immune system, mainly lymphomas. Similarly, involvement of the motor neuron has been described as an uncommon paraneoplastic complication, also in relationship to lymphomas. We report a rare case, given the presence of two uncommon paraneoplastic manifestations such as neuromyotonia and reversible paraneoplastic lower motor neuronopathy secondary to clear cell renal carcinoma.
