Hypercalcaemia in Paget's disease of bone

Albright in 1944 described a syndrome of hypercalcaemia in patients immobilized following fractures through bones affected with Paget's disease. This paper reports a further two cases in which this syndrome was considered the cause of hypercalcaemia with fatal outcome. Both patients had parathyroid adenomata. The literature is reviewed, and it is argued that no firm evidence for the existence of this syndrome has ever been put forward. The finding of hypercalcaemia in Paget's disease of bone should prompt an exhaustive search for its cause.
