MALIGNANT TRANSFORMATION OF MATURE CYSTIC TERATOMA OF THE OVARY: SQUAMOUS CELL CARCINOMA POSTMENOPAUSAL PATIENT

Abstract

Ovarian tumors account for about %6 of female malignancies. %20 of ovarian tumors are germ cell ovarian malignancies and the commonest type of germ cell tumors of ovary is teratoma.1 Teratomas have subtypes like mature, immature and specialized tissue. Of all the germ cell tumors only mature cystic teratoma (MCT) is benign. However, MCT can under go malign transformation in less than %2 of cases. Malign transformation seen especially in postmenopausal patients. Most common type (%80) of malign transformation is squamous cell carcinoma.2 In this article we report a case of squamous cell carcinoma arising from ovarian MCT in a postmenopausal patient.

OVER MATÜR KİSTİK TERATOMDA MALİGN DÖNÜŞÜM: POSTMENOPOZAL HASTADA SKUAMÖZ HÜCRELİ KARSİNOM OLGU SUNUMU

Abstract

Over tümörleri, kadın malignitelerinin yaklaşık %6'sını oluşturur. Over tümörlerinin %20'si germ hücreli malignitelerdir ve overin en sık görülen germ hücreli tümör tipi teratomdur.1 Teratomların matür, immatür ve özelleşmiş doku gibi alt tipleri vardır. Tüm germ hücreli tümörler arasında sadece matür kistik teratom (MCT) iyi huyludur. Ancak MCT, vakaların %2'sinden daha azında malign transformasyona uğrayabilir. Malign transformasyon özellikle postmenopozal hastalarda görülür. En sık görülen malign transformasyon tipi (%80) skuamöz hücreli karsinomdur.2 Bu makalede, postmenopozal bir hastada over MCT'sinden kaynaklanan skuamöz hücreli karsinom olgusunu bildiriyoruz.
