However, the coexistence of multiple epithelial components within a single ovarian lesion is exceedingly rare. We report the case of a multiparous woman presenting with progressive abdominal distension caused by a large ovarian cyst. Imaging revealed a giant, well-circumscribed cystic mass, which was surgically excised. Histopathological evaluation demonstrated a predominantly mucinous cystadenoma with foci of serous and transitional (Brenner-like) epithelial differentiation, without borderline or malignant features. This case represents a rare example of a benign mixed epithelial ovarian tumor and highlights the importance of thorough histopathological examination to avoid misdiagnosis and to better understand mixed M\u00fcllerian epithelial differentiation.<\/jats:p>","DOI":"10.1093\/omcr\/omag040","type":"journal-article","created":{"date-parts":[[2026,2,28]],"date-time":"2026-02-28T12:52:27Z","timestamp":1772283147000},"source":"Crossref","is-referenced-by-count":0,"title":["Benign
