A clear cell cystadenofibroma of the ovary / 대한산부인과학회지

Most clear cell tumors of the ovaries are carcinomas; benign and borderline clear cell tumors are uncommon. We describe here a 52-year-old postmenopausal woman with an ovarian clear cell cystadenofibroma that was misdiagnosed before surgery as a borderline malignant cystic mass of the ovary. The ovarian mass had cystic and solid components. Histological examination revealed widely spaced simple glands embedded in a dense fibrous stroma. The glands were lined with one to two layers of hobnail cells, flattened cells, or cells with abundant clear cytoplasm. The patient successfully underwent a left oophoro-salpingectomy.
