Abstract
Epidermoid and dermoid cysts are benign tumors lined by stratified squamous epithelium. Any region of the body that is covered by squamous epithelium has the potential ability to develop them. Herein, we reported two rare cases with benign cystic teratoma at unusual sites in the genital system. The first case was a 29-year-old G1P1L1 female admitted in our center with pelvic pain 2 months ago. Magnetic resonance imaging (MRI) showed a mass in the posterior cul-de-sac with severe fat content. The patient underwent laparoscopy. Histopathological study of the removed mass showed a dermoid cyst. The second patient was a 35-year-old G3L1Ab2 female who was admitted to our clinic with the chief complaint of abnormal uterine bleeding since one year ago. The ultrasonography represents a hyperecho 65 × 27 mm mass lesion in the endometrial canal progressing toward cervical canal. After laparotomy, a degenerated myoma was resected. Surprisingly, histopathological study of the removed mass showed a mature cystic teratoma. To the best of our knowledge, it is the first study which reports cystic teratomas in the cervix region.
