otherwise of the tumour. Examination of the tumour for stainable fat is also recommended. Furthermore, vaginal cytology for cestrogenic activity and estimation of circulating oestrogenic hormone should also be performed in laboratories where facilities for such investigations exist. The view expressed by Novak and Woodruff (1962) in relation to the functioning properties or otherwise of Brenner tumours of the ovary appears to reflect the current trend of thought. These authors state: "We may have to revise our ideas about the inert behaviour of Brenner and other tumours in view of repeated reports of cases associated with evidence of cestrogen activity. In addition, there is increasing belief that the stroma of certain tumours may be converted into cells capable of steroidal function . . . We are currently willing to admit that the Brenner tumour may on occasion act in an cestrogenic role."
