Bone metastases in children presenting with renal tumours

Abstract

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.
