Figure 1: (a) T2-weighted axial image on magnetic resonance imaging shows hyperintense mass lesion in the endometrial cavity (white arrow); in addition, there is well-defined hypointense ovoid lesion seen in the right adnexa (black arrow). (b) Nests of urothelial cells with coffee bean nuclei present with abundant fibrous stroma indicating benign Brenner of the ovary (H and E ×40). (c) Omentum showing metastatic adenocarcinoma in a case of endometrioid adenocarcinoma (H and E ×40). (d) Immunohistochemistry for estrogen receptor showing nuclear positivity only in fibrous stroma of ovarian Brenner tumor (immunohistochemistry ×40)
