Cutaneous innervation in sensory neuropathies

Abstract

Skin biopsies stained with the sensitive panaxonal marker anti-PGP9.5 demonstrated significant reduction in intraepidermal fibers in sensory neuropathies. This simple and repeatable technique is a reliable method for quantitation of small cutaneous sensory fibers. In addition, skin biopsies may be useful in assessing the course and spatial distribution of involvement in peripheral nerve disease.
