The local precipitation of calcium salts following intramuscular injection of calcium gluconate during treatment of tetany in newborn infants has been reported several times. So far I have seen no paper which mentions the occurrence of abnormal deposits within the body at a place remote from the original site of injection. Because of the rather frightening possibilities that such an eventuality affords, it is my purpose here to report 2 cases in which this phenomenon was observed.
