Abstract

Key clinical message: Protozoans are endemic in the Middle East and diarrhea workup post stem cell transplant should always include stool examination for ova and parasites.

Abstract: We present a case of Blastocystis sp. infection in a multiple myeloma patient who developed diarrhea on day five of post-autologous stem cell transplantation. Diarrhea is a major complication and a potential cause of mortality in this population. Testing for endemic protozoan is recommended.

Keywords: Blastocystis sp.; diarrhea; hominis; multiple myeloma; protozoa; stem cell transplant.
