Ovarian Brenner tumors, accounting for ∼5% of overall ovarian epithelial neoplasm, are often reported in association with mucinous neoplasm. Histogenetically, the two tumors are thought to arise from similar precursors. To date, fewer than 60 borderline Brenner tumors alone have been reported, and the concomitant presence of atypical proliferative components in Brenner and mucinous tumors is even rarer. Therefore, the clinicopathological characteristics and prognosis of patients with the borderline Brenner tumors alone or coexisting with mucinous neoplasm are extremely limited. Herein, we report a unique case of a 53-year-old woman with a unilateral ovarian borderline Brenner tumor associated with focal atypical mucinous epithelial proliferation and her clinical presentations. The clinicopathological features of the tumor are documented and the literature review along with the clinical molecular advances are summarized in this study.
