Bone metastasizing renal tumour of childhood. Histopathological and clinical review of 38 cases.

The histopathological spectrum of a large series of a recently described tumour entity is presented. Seven diagnostic features which may be encountered are described and their frequency discussed. The most striking clinical feature was the marked male preponderance (M:F = 7.6:1). It is suggested that an appreciation of the full histopathological spectrum is necessary to ensure adequate diagnosis.
