title: Mature Teratoma in a Supernumerary Ovary in a Child: Report of the First Case.
abstract: BACKGROUND
  Supernumerary ovary (ie, ovarian ectopia having no anatomic connection with the normally placed ovaries) is a rare gynecologic condition. To the best of our knowledge, only 1 pediatric case of supernumerary ovary has been reported to date in the English literature.
  
  
  METHODS
  A 4-year-old girl was assessed for foul-smelling vestibular discharge and was found to have a fistulous tract with opening near the vaginal orifice. Fistuloscopy revealed hair in the lumen of the tract. Computed tomography scan showed a retroperitoneal mass in continuation of the tract. Excision of the mass revealed a mature teratoma in a retroperitoneal supernumerary ovary.
  
  
  CONCLUSIONS
  Supernumerary ovary, a gynecologic rarity, is even more uncommon in children. Hence, a thorough clinical-radiological-pathological correlation is mandatory to diagnose extragonadal ovarian tumors arising in supernumerary ovaries.
