<jats:title>Abstract</jats:title><jats:p>A 67‐year‐old man presented with acute painful sensory loss, areflexia, ataxia, urinary retention, and severe constipation and became unable to walk within 2 weeks. He died suddenly 5 weeks after the onset of symptoms. Autopsy revealed widespread inflammation of sensory and autonomic ganglia with immunocytochemical evidence of a CD8+ T cell‐mediated cytotoxic attack against ganglion neurons. This observation suggests a novel pathogenetic mechanism of immune‐mediated human ganglion cell damage comparable to mechanisms operating in polymy‐ositis.</jats:p>
