Sural nerve biopsy showing a semi-thin toluidine blue-stained sections (left;
x100) and ultrastructure (right; x3870). Enlarged axons are seen (arrows)
with attenuated myelin sheaths. The absence of intermediate filaments in
other cell types, osmiophilic condensation, onion bulb formation, and
inflammatory infiltrate suggested n-hexane exposure.
