title: Diagnosis of lymphoma in a continuous ambulatory peritoneal dialysis patient by peritoneal fluid cytology.
abstract: A 72-year-old woman with diabetic nephropathy receiving continuous ambulatory peritoneal dialysis for 1 year presented with recurrent episodes of sterile cloudy dialysate. Abdominal ultrasound and computed tomography demonstrated retroperitoneal masses. Cytology of the dialysis fluid revealed large atypical lymphocytes with light chain restriction, strongly suggestive of lymphoma. Fine-needle aspiration of the retroperitoneal masses showed cells with identical cytologic and immunocytochemical staining characteristics. This is the first report of de novo lymphoma diagnosed in a continuous ambulatory peritoneal dialysis patient by cytologic analysis of the dialysis effluent.
