Abstract:
Ovarian squamous cell carcinoma constitutes less than 2% of all gynecologic malignancy. Most of ovarian primary squamous cell carcinoma arise in mature dermoid cyst. Malignant transformation occurs in less than 2% of benign mature teratoma. Of all three germ layers, the ectoderm is thought to be commonest to undergo malignant change, hence sguamous cell carcinoma is by far the most frequent seen tumor that is over 80% of reported cases in large series followed by the much rare adenocarcinoma, melanoma, and carcinoid. Most patients of ovarian squamous cell carcinoma were postmenopausal. Several authors had reported the poor prognosis of this malignancy but there is no consensus on optimal therapy. Due to its rarity, there is also no consensus regarding the efficacy of postoperative therapy. A Rare presenting symptom associated ovarian squamous cell carcinoma is rectal mass secondary to invasion into the distal rectum. We also present a case of rectal invasion of ovarian squamous cell carcinoma.
