Most frequent histological type was serous carcinoma (SC) followed by mucinous carcinoma (MC), endometrioid carcinoma (EC), clear cell carcinoma (CC), malignant brenner tumor (MBT) and seromucinous carcinoma (SMC) (60.6% n=20, 15.2% n=5, 9.1% n=3, 9.1% n=3, 3% n=1, and 3% n=1 respectively).

Patients with a histologic diagnosis of Brenner tumor of the ovary who underwent laparotomic or laparoscopic surgery for any reason between 2005 and 2015 were identified from the database of Ankara University's Faculty of Medicine Department of Obstetrics and Gynecology.

[sup][1],[3],[4],[5] Despite this, the direct extension of a Brenner tumor to the iliacus and psoas muscles is plausible as the ovaries are anatomically adjacent to the iliopsoas.
The underlying etiology should not be determined by guesswork, however, given that extensive sampling of the surgical specimen is required to rule out the presence of a teratoma, an occult endometrioid carcinoma, or a Brenner tumor. (3) With a diagnosis of squamous cell carcinoma of the ovary, full gynecologic staging should be undertaken, including completion of a total abdominal hysterectomy and a bilateral salpingo-oophorectomy, as well as peritoneal, omental, and lymph node biopsies as the case may dictate.

Ovarian masses with fibrous components include fibroma, fibrothecoma, cystadenofibroma, and Brenner tumor. The fibrous components of these masses tend to have very low signal intensity on T2-weighted MRI.
Thyroid-type carcinoma arising in struma ovarii may mimic other primary ovarian tumors, such as granulosa cell tumor, Brenner tumor, papillary serous cystadenoma, or cystadenocarcinoma.
Brenner tumors are incidental, usually benign epithelial tumors occurring in the 5th - 7th decades, usually demonstrating calcifications.
They show a high predisposition to ovarian cancer with the most frequent observed histotypes are gonadoblastomas and dysgerminomas, followed by Brenner tumors, malignant teratomas, and mixed endodermal sinus tumors.[sup][2],[5] The lifetime risk of gonadal tumors is in range of 15–35%.

Among benign findings that were managed surgically, 47% were serous cystadenomas, 13% were hemorrhagic cysts, 9% were fibromas, thecomas, or Brenner tumors, and the rest were fairly equally divided between hydrosalpinx or paratubal cysts; endometriomas; and mucinous cystadenomas, leiomyomas, and cystic teratomas.
