Which of the following is the MOST common benign epithelial (surface epithelial-stromal) tumour of the ovary?
- A Mucinous cystadenoma
- B Serous cystadenoma ✓
- C Brenner tumour
- D Endometrioid adenofibroma
Correct answer: B. Serous cystadenoma
Explanation
Serous cystadenoma is the most common benign ovarian epithelial neoplasm and is bilateral in roughly 20 percent of cases. It is lined by ciliated columnar epithelium resembling fallopian tube. Mucinous cystadenoma, though frequently larger and multilocular, ranks second in frequency. Brenner tumours are uncommon and usually incidental findings. This frequency ranking is a standard exam fact.
