title: Congenital paraurethral cysts in two newborn girls: differential diagnosis, management strategies, and spontaneous resolution.
abstract: BACKGROUND
  At least five types of interlabial masses of different etiologies may present in a female neonate. The more serious type of interlabial mass must be differentiated from the benign and self-resolving paraurethral or hymenal cyst. Clues include appearance and color of the mass and the location of the mass in relation to the urethral meatus and the vaginal opening. Clinicians should be able to distinguish lesions that require aggressive intervention, i.e. surgery, from those that self-resolve and merely require observation.
  
  
  METHODS
  Two unrelated newborn girls each had a protruding faint-yellow-colored spherical interlabial cyst. The cyst was located anterior to the vaginal orifice and partially obscured the urethral meatus. Neither girl had any voiding problems. No other congenital anomalies were detected. Both cysts resolved rapidly and completely without surgical intervention.
  
  
  CONCLUSIONS
  Paraurethral cysts of the newborn and hymenal cysts rarely cause urinary obstruction or spotting, and are self-resolving. When positively identified, no evaluation of upper urinary tract is required and neither aspiration of cyst contents or marsupialization procedure is necessary.
