title: Hypercalcaemia in "non-secretory" myeloma.
abstract: A patient is described with hypercalcaemia due to myelomatosis without paraproteinaemia or Bence-Jones proteinuria. Immunological investigations yielded some evidence of intra-cellular immunoglobulin production. Histological features suggested the secretion of osteoclast activating factor. Relevant experimental work in support of this interpretation is reviewed.
