A 33 year-old male homosexual infected with human immunodefiency virus
type I developed an asymmetrical and painful neuropathy in the lower
limbs. Neuro-muscular biopsy showed a necrotizing vasculitis. There we
re no clinical features indicative of systemic vasculitis. Prednisone
therapy dramatically improved the neuropathy, without adverse effects.
Although rare, necrotizing arteritis must be considered in HIV1 patie
nts with neuropathy, especially in case of mononeuropathy multiplex an
d when immunodepression is mild or absent, since a successful corticos
teroid therapy can be prescribed.
