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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
