Visceral leishmaniasis (Indian kala-azar) caused by infection due to the protozoan Leishmania donovani is endemic in the Indian subcontinent and adjoining regions. Prolonged fever, hepatosplenomegaly, anaemia and pancytopenia, in the appropriate setting, are important clinical markers towards the diagnosis. Diagnosis is established by blood film or bone marrow examination for Leishman Donovan (LD) bodies and/or culture. Treatment with sodium stibogluconate, pentamidine isethionate or even amphotericin B is usually successful. We report the first case of culture-proven visceral leishmaniasis in Singapore, in a 30-year-old Bangladeshi worker who presented with pyrexia of unknown origin (PUO). He had the classical constellation of symptoms and signs as mentioned above. Diagnosis was confirmed by culture on the Novy, NcNeal and Nicolle (NNN) medium. He was successfully treated with 20 days of pentamidine isethionate daily infusions at a dose of 2 mg/kg/day.
