Visceral leshmaniasis diagnosed on duodenal biopsy in a child.

Visceral leishmaniasis is usually easy to recognize when clinical presentation is complete: splenomegaly, fever and palor associated to pancytopenia, hypoalbuminaemia and hypergamma globulinemia. Bone marrow smears, culture and serology confirm the diagnosis. We report the case of an infant in whom clinical and biological findings are suggestive of leishmaniasis and the diagnosis confirmed only by duodenal biopsy.
