Brenner and transitional cell tumours of the ovary. Report of three cases.

Three rare epithelial ovarian tumours, one malignant Brenner tumour, one transitional cell carcinoma and one Brenner tumour of borderline malignancy, are presented with special emphasis on the diagnostic, prognostic and therapeutic modalities. Because the prognosis of transitional cell carcinoma of the ovary is worse, as in our case, than that of the malignant Brenner tumour, this classification is justified.
