A survey of bone metastases in 132 children presenting with renal tumours has been carried out using material from the Manchester (England) Children's Tumour Registry during the period 1954 to 1976. Seven such cases were found. Only one of the 117 Wilms' tumours developed bone metastases. The remainder included carcinoma (1/4), 'bone metastasising renal tumour of childhood' (2/3), atypical tumours (2/2), and lymphosarcoma (1/1). Bone metastases from true nephroblastoma seem to be an exceptional finding.

Plasma calcium was measured routinely as a part of profile screening of patients admitted to a geriatric department. Pathological hypercalcaemia was found in 1.33% of those screened, the cause being bone metastases (29%), hyperparathyroidism (21%), bronchial carcinoma without bone metastasis (18.5%), lymphosarcoma without bone metastasis (8%) and multiple myeloma (2.5%). There remained a further group of patients with hypercalcaemia and renal failure (21%) in whom diagnosis was often obscure. Where renal function was normal, discriminant analysis showed that the four main diagnostic groups were biochemically distinguishable. Discriminant analysis thus seems likely to be of practical value in the differential diagnosis of hypercalcaemia in elderly patients with normal renal function, but requires prospective validation.
