Small fiber neuropathy in the chronic phase of Chagas disease: a case report.

We describe the occurrence of small fiber neuropathy in a patient affected by Chagas disease in the indeterminate phase. After the exclusion of all the possible etiologies of small fiber neuropathy, the disorder was considered related to Trypanosoma cruzi infection. Although a peripheral involvement has been described in Chagas disease, this is the first report of a selective involvement of small fibers.
