Fig. 2.50 Borderline Brenner tumour. A large, papillary, polypoid component protrudes into a cystic space. Macroscopy Transitional cell carcinomas are bilateral in approximately 15% of cases {139} and a re macroscopically indistinguishable f rom other surface epithelial-stro m a l tumours {139,2676}. Tumour spread and staging At the time of diagnosis transitional cell c a rcinomas have spread beyond the ovary in over two-thirds of cases {2676} Histopathology Transitional cell carcinomas re s e m b l e those occurring in the urinary tract and lack a benign or borderline Bre n n e r tumour component {139,2676}. Typically, they are papillary with multilayered transitional epithelium and a smooth luminal border ("papillary type"). A nested pattern characterized by malignant transitional cell nests irregularly distributed in fibrotic stroma ("malignant Brenner-like type") has been described {2464,2465}. As in urothelial carcinoma, foci of glandular and/or squamous diff e re n t i a t i o n may occur. Very commonly, transitional cell carcinoma is admixed with other epithelial cell types, primarily sero u s adenocarcinoma. Transitional cell carcinomas lack the prominent stromal calcification characteristic of some benign and malignant Brenner tumours. Grading Transitional cell carcinomas should be graded utilizing criteria for transitional cell carcinoma of the urinary tract. A Histogenesis The term transitional cell carcinoma is not uniformly accepted, and overlapping f e a t u res with other epithelial-stro m a l tumours, particularly serous carcinoma, are present. It is important that strict histological criteria be applied to establish the diagnosis {2465}. Not only an architectural but also a histological resemblance to transitional epithelium is required. The frequent association with epithelial-stromal tumours of other types strongly suggests a surface epithelial origin {2465}. In addition, several immunohistochemical studies have demonstrated that the tumour lacks a urothelial phenotype {2115,2371}. Thus, the ovarian neoplasm shows histological but not immunohistochemical similarities to transitional cell carcinoma of the urinary bladder. Prognosis and predictive factors The overall 5-year survival rate for transitional cell carcinoma is 35%. Some, but not all, investigators have re p o rt e d greater chemosensitivity and higher 5- year survival in patients whose metastases are composed purely or predominantly of transitional cell carcinoma {564, 1232,2676}. Immunoprofile Ovarian transitional cell carcinomas have an immunoprofile that differs from transitional cell carcinomas of the urinary tract and closely resembles that of ovarian s u rface epithelial-stromal tumours. Ovarian transitional cell carcinomas are consistently uroplakin, thrombomodulin and cyokeratin 13 and 20 negative and CA125 and cytokeratin 7 positive {2115, 2371}.

Malignant Brenner tumour Definition An ovarian tumour containing invasive transitional cell aggregates as well as benign nests of transitional epithelium set in a fibromatous stroma. Epidemiology The great majority of malignant Brenner tumours occur in women 50-70 years old {1110,1868,2676}. Only 5% of Brenner tumours are malignant {1110,1868}. Clinical features Most patients seek medical attention because of an abdominal mass or pain {139,2460,2461}. A few patients present with abnormal vaginal bleeding. Macroscopy Malignant Brenner tumours are typically large with a median diameter of 16-20 cm and typically have a solid component resembling benign Brenner tumour as well as cysts containing papillary or polypoid masses {2461}. Tumour spread and staging Malignant Brenner tumours are bilateral in 12% of cases {139,452}. About 80% of malignant Brenner tumours are stage 1 at the time of diagnosis. Histopathology In malignant Brenner tumours there is s t romal invasion associated with a benign or borderline Brenner tumour component {139}. The invasive element is usually high grade transitional cell carcinoma or squamous cell carc i n o m a , although occasional tumours are composed of crowded, irregular islands of malignant transitional cells with low grade features {2460}. Glandular elements may be admixed, but pure mucinous or serous carcinomas associated with a benign Brenner tumour component should not be diagnosed as a malignant Brenner tumour. Foci of calcification are occasionally prominent. Immunoprofile The very small number of malignant Brenner tumours studied have exhibited a benign Brenner tumour immunoprofile in that component with a variable pattern of antigen expression in the invasive component; uroplakin immunopositivity has occurred in some {2371}. Fig. 2.52 Benign Brenner tumour. Sectioned surface is firm, lobulated and fibroma-like with a small cystic component. Prognosis and predictive factors When confined to the ovary, malignant B renner tumours have an excellent pro g- nosis. Patients with stage IA tumours have an 88% 5-year survival, and those with high stage malignant Bre n n e r tumours have a better prognosis than stage matched transitional cell carc i n o- mas {139}. Borderline Brenner tumour Synonyms Brenner tumour of low malignant potential, proliferating Brenner tumour (for cases with low grade features). Definition An ovarian transitional cell tumour of low malignant potential with atypical or malignant features of the epithelium but lacking obvious stromal invasion. Epidemiology Only 3-5% of Brenner tumours are borderline {1110,1868}. Tumour spread and staging Borderline Brenner tumours are confined to the ovary and, with rare exceptions, have been unilateral {1110,1868,2461, 3144}. Clinical features Most patients seek medical attention because of an abdominal mass or pain {139,2460,2461}. A few patients present with abnormal vaginal bleeding. Macroscopy Borderline Brenner tumours are typically large with a median diameter of 16-20 cm. They usually have a solid component resembling benign Brenner tumour as well as a cystic component containing a papillary or polypoid mass {2461}. Histopathology B o rderline Brenner tumours show a greater degree of architectural complexity than benign Brenner tumours typified by branching fibrovascular papillae surfaced by transitional epithelium often protruding into cystic spaces. The transitional epithelium manifests the same spectrum of architectural and cytological features encountered in urothelial lesions of the urinary tract. By definition, there is no stromal invasion. A benign Brenner tumour component is typically present but may be small and easily overlooked. The mitotic rate is highly variable but may be brisk, and focal necrosis is common. Mucinous metaplasia may be a prominent feature. The diagnostic criteria and terminology applied to the intermediate g roup of transitional cell tumours is somewhat controversial {2461,2605}. Some have advocated categorizing tumours with low grade features as "proliferating" rather than borderline {2461}, and others designate those resembling grade 2 or 3 transitional cell carcinoma of the urinary tract as "borderline with intraepithelial carcinoma" {2605}. Prognosis and predictive factors No Brenner tumour in the intermediate category without stromal invasion has metastasized or caused the death of a patient {1110,2461}. Benign Brenner tumour Definition An ovarian transitional cell tumour composed of mature urothelial-like cells arranged in solid or cystic circumscribed aggregates within a predominantly fibromatous stroma. Epidemiology Benign Brenner tumours account for 4- 5% of benign ovarian epithelial tumours {1409,1502,1970,2865}. Most benign Brenner tumours (95%) are diagnosed in women 30-60 years old {753,905,1868, 2460,2461,2676,2685,3073,3186}. Clinical features The majority of patients with benign Brenner tumours are asymptomatic; over 50% of tumours are less than 2 cm and are typically discovered incidentally in ovaries removed for some other reason {753,905,2685,3073}. In only 10% of cases is the tumour larger than 10 cm; 142 Tumours of the ovary and peritoneum
