Cloudy dialysate in a patient on continuous ambulatory peritoneal dialysis (CAPD) most commonly reflects an increased number of leukocytes secondary to bacterial peritonitis. In the absence of infection, increased quantities of eosinophils, red blood cells, fibrin, or chyle may produce cloudy dialysate in these patients. We report the case of a CAPD patient presenting with cloudy dialysate and symptoms suggestive of bacterial peritonitis. Analysis of the dialysate revealed no microorganisms. The turbidity of the dialysate was related to an increased number of atypical lymphocytes consistent with a B cell lymphoma. Peritoneal dialysis continued uneventfully despite neoplastic disease within the peritoneum. It is recommended that malignant involvement of the peritoneum be added to the differential diagnosis of cloudy dialysate occurring in CAPD patients.
