Inflammatory peripheral neuropathy following high dose chemotherapy and autologous bone marrow transplantation

A 40-year-old man with non-Hodgkin's lymphoma developed severe ascending sensorimotor neuropathy 10 days after treatment with high dose chemotherapy and autologous bone marrow rescue. The neuropathy had axonal plus demyelinating features on electrophysiological studies. Sural nerve biopsy showed heavy infiltration of the epineurium and endoneurium with mononuclear cells. The patient had no other evidence of graft-versus-host disease. He failed to respond to plasmapheresis but responded to high dose steroids.
