title: Carcinomatous neuropathy associated with hepatic cell carcinoma: an autopsy case report.
abstract: A 76-yr-old male patient with carcinomatous neuropathy associated with hepatic cell carcinoma, whose initial symptom was deep sensory disturbance followed by muscle weakness is described. The onset was subacute, followed by slow progression. Sural nerve biopsy, as well as electrophysiological examinations, revealed severe axonal degeneration without any evidence of demyelination. The autopsy findings were similar to findings described in the literature on carcinomatous neuropathy. Although carcinomatous neuropathy is usually associated with lung cancer, this report describes an association with hepatic cell carcinoma. The patient also had motor nerve involvement with positive serum anti-GM1 ganglioside antibody which decreased after immunosuppressant therapy in parallel with recovery of muscle weakness. The anti-GM1 ganglioside antibody may be involved in the pathogenesis of motor disturbance in the present case.
