Rectal ulcer in a hemodialysis patient receiving Sodium Polystyrene
sulfonate ( Sodium Kayexalate®)
Kayexalate® is associated with gastrointestinal injury that can be
fatal. Physicians must be aware of the adverse events when prescribing
this therapy. Clinical data and medication history should follow the
biopsy material given to the pathologist, who will look for Kayexalate®
crystals. Pathologists and physicians should work hand in hand.
