Pruritic rash and eosinophilia in a patient receiving peritoneal dialysis.

A 28-year-old woman with end-stage renal disease maintained on peritoneal dialysis developed a hyperpigmented macular pruritic rash on multiple parts of her body associated with an eosinophilia of 22%. The consulting allergist suspected a silicone allergy from the peritoneal dialysis catheter. A patch test confirmed this diagnosis. Treatment with both topical and systemic steroids was ineffective. Following a living nonrelated renal transplant and removal of the catheter the rash and eosinophilia resolved.
