Cloudy fluid, cloudy diagnosis.

Abstract

Here, we report a case of a patient with cloudy effluent that was initially diagnosed as bacterial peritonitis. The persistence of a cloudy effluent despite antibiotic therapy led to an extensive peritoneal dialysis (PD) effluent analysis, with the final diagnosis being high-grade B-cell lymphoma. This case will increase the awareness of this rare presentation of a lymphoproliferative disorder reminding clinicians to consider this diagnosis as a part of the differential diagnosis PD effluent.
