A 51-year-old woman with a 20-year history of renal transplantation during the end-stage of chronic renal failure caused by tubulointerstitial nephritis. She died of chronic graft rejection. An interstitial calcification limited to 1. and 2. left segments was encountered as an incidental autoptic finding. There were two unusual microscopic findings, i.e., no involvement of arterioles and larger vessel inclusive veins, and a foreign-body response to some of the calcified tissue.
