[Leukocytoclastic vasculitis associated with tumors]

We report 6 patients with the diagnosis of leukocyclastic vasculitis, with a neoplasia as the only clinical manifestation associated. Evolution of vasculitis was chronic or recidivant; rapid erythrocyte sedimentation rate, positivity for rheumatoid factor, and hypocomplementemia were frequent in our cases. The clinical course of vasculitis and tumour was discordant. The authors believe that there are not sufficient data to demonstrate an association between leukocytoclastic vasculitis and tumours.
