Visceral leishmaniasis in a psoriatic arthritis patient treated with methotrexate.

Visceral leishmaniasis, in Greece, represents a relatively rare, potentially fatal clinical entity. Here we describe a case of visceral leishmaniasis infection in a 65-year old Greek male with psoriatic arthritis treated with methotrexate, who presented with high grade fever, chills, splenomegaly, pancytopenia and polyclonal hypergammaglobulinaemia. A diagnosis of visceral leishmaniasis was finally established. Visceral leishmaniasis should be included in the differential diagnosis for infections in patients receiving methotrexate for rheumatic diseases, especially in endemic areas.
