The Johns Hopkins Medicine Cutaneous Nerve Laboratory

The Department of Neurology at Johns Hopkins offers comprehensive resources for the clinical evaluation, biopsy, and pathological interpretation for peripheral nerve conditions.

The Johns Hopkins Medicine Cutaneous Nerve Laboratory is a diagnostic and research laboratory that analyzes skin samples to diagnose and monitor small fiber neuropathies. 3mm skin punches are analyzed for epidermal nerve fiber density and morphological changes. A diagnosis of small fiber neuropathy can be made based upon these results. Cutaneous nerve/skin biopsies can also be useful to diagnose patchy numbness as might occur in a mononeuropathy such as meralgia paresthetica, or in a mononeuritis multiplex.

Our services are offered to both practicing physicians and patients. We also serve as a core laboratory for clinical trials. For more information, please contact us at: 410-614-6399 or skin_biopsy@jhmi.edu.
