Background. - Visceral leishmaniasis occurring in malnourished subjects can
have an uncommon course, which explains difficulties in its diagnosis.
Case report. - A 22-month-old infant was admitted because of malnutrition a
nd prolonged fever. The bacteriological investigation was negative. When hi
s nutritional status improved, he developed a splenomegaly. The medullogram
confirmed the diagnosis of visceral leishmaniasis. The course was then fav
orable with treatment by pentavalent antimonial.
Conclusion. - Malnutrition constitutes a risk factor of opportunist parasit
ic disease such as leishmaniasis. Its diagnosis can be very difficult. (C)
