Squamous cell carcinoma arising in an ovarian mature cystic teratoma: A case report

Abstract

Pure primary squamous cell carcinoma (SCC) of the ovary is extremely rare. SCC can also arise in a mature cystic teratoma or dermoid cyst, in an ovarian endometrioma or in a brenner's tumor, but such malignant transformations are also quite rare. Development of SCC in a mature cystic teratoma (MCT) has been reported sporadically in less than 2% cases only. Here in our present study, we are reporting such a rare case of 65 years old postmenopausal woman who was diagnosed as having squamous cell carcinoma developed in a mature cystic teratoma of the ovary at our institute. This diagnosis was given on the basis of clinical (patient's history and examination), radiological (CT scan) and pathological (histopathology report) findings. We are also going to discuss other similar cases with review of literature. The only aim of this present study is to share our experience of such rare diagnosis with others.
