Unilateral Ovarian Dermoid Cyst Accompanied by an Ipsilateral Paratubal Cyst in a Girl with Proteus Syndrome Discovered by Laparoscopic Surgery

Abstract

Background: Proteus syndrome is a rare hamartomatous disorder characterized by the overgrowth of multiple tissues in a mosaic pattern. Tumors of genitourinary tract in Proteus syndrome are uncommon. Case: We here report a 5-year-old girl with Proteus syndrome who developed a cystic mass in the pelvic cavity. The cyst was discovered by ultrasonographic examination and finally proved to be a unilateral ovarian dermoid cyst accompanied by an ipsilateral paratubal cyst by laparoscopic surgery. Summary and Conclusion: Proteus syndrome accompanied by an ovarian cyst is rare in girls. The possibilities of underlying ovarian cyst required for surgical intervention should be considered in Proteus syndrome. ？ 2010 North American Society for Pediatric and Adolescent Gynecology.
