[First manifestation of a leucocytoclastic vasculitis in the colon: case report and differential diagnostic aspects]

Abstract

This report presents a female patient suffering from chronic diarrhea, who developed palpable purpura on the lower extremities 8 weeks after onset of the gastrointestinal symptoms. Biopsies obtained from the colon and skin showed leukocytoclastic vasculitis. Possible triggers or underlying diseases could not be found, and the patient recovered without specific treatment for vasculitis. Possible differential diagnoses and the difficulties in classifying vasculitides are discussed in the present report.
