Recurrent leishmaniasis infection isolated in the pleural fluid

Abstract

We present a rare case of recurrent leishmaniasis infection in a female in her 80s who re-presented with a pleural effusion. The patient was initially investigated as an outpatient for cytopenia and underwent a bone marrow biopsy which subsequently diagnosed visceral leishmaniasis. Following full treatment, and apparent recovery, she re-presented with pleural effusion, hypoalbuminaemia and cytopenia. Leishmania was eventually isolated in a pleural fluid sample obtained on therapeutic drainage, and she was treated for a recurrence at a tertiary infectious disease unit. This interesting and challenging case demonstrates the importance of suspecting leishmaniasis recurrence in previously treated cases and the diagnostic benefit of pleural fluid analysis in the context of suspected leishmaniasis.
