This case report describes a patient presenting with bilateral primary squamous cell carcinoma of the ovary associated with ovarian endometriosis. The authors note that while most primary ovarian squamous cell carcinomas arise in mature cystic teratomas, this rare variant can occur in association with endometriosis or Brenner tumors. The patient underwent postoperative systemic chemotherapy, reflecting the lack of consensus on optimal treatment protocols for this malignancy due to its poor prognosis compared to other epithelial ovarian cancers. This paper is centrally about endometriosis — specifically, it documents the malignant transformation of ovarian endometriosis into squamous cell carcinoma.

Abstract

Primary ovarian squamous cell carcinoma is the one of the rarest of all ovarian malignancies. Most of them arise in mature cystic teratoma and a minority of them associated with endometriosis, arising in a Brenner tumor, or appearing in pure form. Due to its rarity, there is no agreement concerning the efficacy of postoperative treatment of primary squamous cell carcinoma of the ovary, although the prognosis of this type of tumor is much worse than that of other epithelial ovarian cancers. We describe a patient with squamous cell carcinoma of the ovary in association with ovarian endometriosis, who has undergone postoperative systemic chemotherapy.
