Purpose
Mucinous ovarian tumors, i.e., mucinous cystadenomas, have been found to coexist with Brenner tumors and therefore studied more commonly. We report here this case report with emphasis on its clinical features, diagnostic, morphological and histological features.
Method
A 70-year-old patient who attended outpatient department at GCRI, Ahmedabad, underwent exploratory laparotomy after proper surgical evaluation for bilateral adnexal masses on clinical examination and imaging.
Result
In this case report, Brenner tumor was found to coexist with borderline mucinous cystadenocarcinoma in left and right ovary, respectively, on frozen section. The final histopathology showed borderline mucinous cystadenocarcinoma in right ovary and benign Brenner tumor in left ovary.
Conclusion
The rate of Brenner tumor coexisting with mucinous cystadenoma has been reported as 1.3%, and the rate of mucinous adenocarcinoma accompanying Brenner tumor has been reported as 9%.
