Abstract
Introduction: Transitional cell carcinoma of the ovary is a rare, recently recognized, subtype of ovarian surface epithelial carcinoma. Transitional cell carcinoma is sufficiently different from malignant Brenner tumour (MBT) in that it is reasonable to suppose that ovarian TCC arises directly from pluripotential surface epithelium of the ovary and from cells with urothelial potential, rather than from a benign or proliferative Brenner tumor precursor.
Case presentation: We present a case of TCC of the ovary, managed by total abdominal hysterectomy and bilateral salpingo-oophorectomy with omentectomy.
Conclusion: Primary TCC of the ovary is a rare subtype of epithelial ovarian tumours and their response to chemotherapy is better than that for other types of ovarian cancers.

Key words: Transitional cell carcinoma, malignant Brenner tumour, pluripotential surface epithelium, total abdominal hysterectomy, bilateral salpingo-oophorectomy with omentectomy.
