Neuropathic arthropathy caused by paraneoplastic sensory neuropathy. A case report.

Abstract

Neuropathic arthropathy of both knees after paraneoplastic sensory neuropathy developed in a 64-year-old woman. The patient was found to have small cell lung cancer 2 months after the onset of a sensory neuropathy that was diagnosed as paraneoplastic sensory neuropathy, a nonmetastatic neurologic complication in patients with malignancy. The onset of paraneoplastic sensory neuropathy was followed by the gradual onset of neuropathic arthropathy. This is the first well documented report on neuropathic arthropathy in a patient with paraneoplastic sensory neuropathy.
