RESUMO
Patients with acquired immunodeficiency syndrome are often susceptible to atypical dissemination of visceral leishmaniasis. Digestive localizations seem to be relatively frequent. Colonic localizations reported in the literature are endoscopically normal or show superficial mucosal lesions. We describe an original case of leishmaniasis associated with a colonic pseudotumoral stenosis with perforated ulcer penetrating in the mesocolon. Striking inflammation of mesenteric blood vessels, even far from the ulcer, suggested an ischemic mechanism for the colonic stenosis. These findings raise the hypothesis that vasculitis is secondary to mucosal parasitic infection.
