Most cases of primary squamous cell carcinoma of the ovary are associated with mature teratoma or Brenner tumor, and a few cases are related to endometriosis of the ovary. But a few cases of ovarian primary squamous cell carcinoma have occurred without clear associated etiology. Although some of them are concurred with cervical carcinoma in situ, they have not shown clear associations with the ovarian primary squamous cell carcinoma. We report a case of primary squamous cell carcinoma of the ovary appearing in pure form. A left ovarian mass was detected in a 43-year-old woman. A total hysterectomy and bilateral adnexectomy with regional lymph node dissection were performed. Histologically, the tumor was predominantly composed of polygonal tumor cells with keratinization and intercellular bridge, dyskeratotic cells, necrotic cell debris, and inflammatory cells. Also, metastasis to paraaortic lymph node was detected.
