Painful neuropathy vasculitis in 2 patients with long-standing human immunodeficiency virus-1 infection.

We describe 2 most unusual cases of distal symmetrical painful polyneuropathy in patients with long-standing HIV-1 infection well controlled by HAART. Sural nerve biopsies revealed vasculitis in both cases and steroid therapy led to resolution of symptoms not influenced by analgesics and anti-inflammatory drugs. These unusual cases outline the importance of nerve biopsies in order to reach a diagnosis.
