Paraneoplastic neuropathy.

Paraneoplastic neuropathies occur in various settings. This article focuses on recent neuroimmunologic findings regarding paraneoplastic neuropathy. Entities such as sensorimotor and sensory neuropathy, sensory neuronopathy; motor, autonomic, demyelinating and vasculitic mononeuropathies; and cranial nerve lesions and neuropathies in association with leukaemia and paraproteinaemas are discussed. Finally, the article considers the issue of 'overlap' syndromes--the occurrence of several paraneoplastic phenomena in the same patient.
