title: A case of congenital myofibroma of the orbit presenting at birth.
abstract: OBJECTIVE
  The purpose of this report is to highlight a rare cause of congenital proptosis.
  
  
  METHODS
  This is a case report.
  
  
  RESULTS
  We present a case of a baby girl born with a large myofibroma in the right retrobulbar space. This case is unusual because it presented from birth and was in a critical location. A prenatal ultrasound performed two days prior to birth did not reveal this mass to the technician or obstetrician. At birth, the tumor induced severe proptosis, with the eyelids unable to close around the globe. Deterioration of the ocular surface secondary to exposure was evident immediately after birth. One week after birth, the mass was excised by the Oculoplastics service in conjunction with a Neurosurgical team using a transcranial approach. The tumor was diagnosed by histopathology and immunologic staining as a myofibroma, a rare condition.
  
  
  CONCLUSIONS
  Orbital myofibroma is a rare cause of congenital proptosis presenting at birth.
