The authors report a case of non fatal visceral leishmaniasis in a renal transplant recipient and underline the fact that immunosuppressive treatments facilitate the occurrence of this disease. In patients with fever, pancytopenia and spleen enlargement, it is capital to inquire whether they have sojourned in a country where leishmaniasis is endemic. The diagnosis is then confirmed by bone marrow examination. Treatment rests on antimony derivatives, but these must be handled with caution in immunocompromised patients.
