We describe the case of a young girl suffering from thermoregulation disturbances, painless fractures and arthropathy since early childhood. The patient was diagnosed as having a hereditary sensory autonomic neuropathy. Although needle EMG, conventional nerve conduction studies and somatosensory evoked potentials gave normal results, sympathetic skin responses (SSRs) were absent. Sural nerve biopsy showed a substantial reduction in the number of small myelinated and unmyelinated fibers. We emphasize the importance of SSR testing in revealing a condition which is otherwise difficult to identify by electrophysiological techniques. The combined evidence of functional and morphological findings is strongly suggestive of selective peripheral nerve involvement.
