Atypical presentation of visceral leishmaniasis (kala-azar) from non-endemic area.

Leishmaniasis is a major public health problem in various part of world; it has also emerged in new geographic areas and host populations. Visceral infection can remain subclinical or become symptomatic, with an acute, subacute or chronic course. Kala-azar, or visceral leishmaniasis (VL), presents as fever, pancytopenia and hypergammaglobulinaemia. The presence of splenomegaly is characteristic of VL. It may be absent in immunocompromised patients, who may present atypically. Absence of splenomegaly is rare in immunocompetent patients, though it may occur in the early stages. Atypical presentations can be challenging to the clinician. This paper presents an atypical presentation of kala-azar, with multi-organ failure in the absence of splenomegaly or fever.
