The Art of Coexistence: A Rare Case of Mucinous Tumour with Brenner Tumour of Ovary

Ovarian tumours are the most common gynaecological neoplasm. Surface epithelial stromal tumours are the most common neoplasms of the ovary; mixed epithelial tumours are rare. We present a case of a postmenopausal female who presented with a right-sided abdominal lump for 6 months. USG and MRI showed a multiseptate cystic lesion with a central nodule. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was done. On histopathological examination, the diagnosis of mucinous cystadenoma with benign Brenner tumor was made. Mixed epithelial tumors are rare and pose a diagnostic dilemma; multiple histopathological sections should be evaluated to rule out the presence of dual neoplasm.
