Sensory ataxic neuropathy and esophageal achalasia in a patient with Sjogren's syndrome.

We describe a patient who developed an ataxic sensory syndrome associated with xerophthalmia and progressive dysphagia with regurgitation. Electrophysiological findings were consistent with an axonal sensory neuropathy, and superficial peroneal nerve biopsy showed a reduction in number of myelinated fibers with epineurial inflammation. Rheumatoid factor, anti-SSA/SSB and antinuclear antibodies were positive and a diagnosis of Sjogren's syndrome was made. An endoscopic investigation revealed esophageal achalasia. We suggest that there may be a common autoimmune mechanism directed to different targets on the basis of this rare association.
