[Visceral leishmaniasis, pemphigus and immunosuppressive treatment: case report from Morocco]

Atypical forms of visceral leishmaniasis associated with immunosuppressive treatment are difficult to diagnose and cause high mortality. The purpose of this report is to describe a case involving a 42-year-old patient living in a leishmaniasis-endemic area, who was undergoing immunosuppressive treatment using corticosteroids and methotrexate for pemphigus. Despite clinical and laboratory findings consistent with visceral leishmaniasis, detection of Leishmania bodies was a coincidental finding of cytological examination of bone marrow during workup for pancytopenia and associated clinical signs. This case argues in favor of systematic screening for this opportunistic parasitic disease before undertaking immunosuppressive treatment in patients presenting risk factors and consistent clinical/laboratory findings.
