title: A RETROPERITONEAL TUMOUR OF THE CHEMODECTOMA TYPE.
abstract: A tumour of the chemodectoma type arising in the retroperitoneal space and projecting between the layers of the transverse mesocolon is reported. Attention is drawn to the lack of correlation between the varied histological features and clinical findings in this group of tumours and the inadvisability of forecasting behaviour.
