title: [Partial facial duplication (a rare diprosopus): Case report and review of the literature].
abstract: BACKGROUND
  Diprosopus, or partial facial duplication, is a very rare congenital abnormality. It is a rare form of conjoined twins. Partial facial duplication may be symmetric or not and may involve the nose, the maxilla, the mandible, the palate, the tongue and the mouth.
  
  
  METHODS
  A male newborn springing from inbred parents was admitted at his first day of life for facial deformity. He presented with hypertelorism, 2 eyes, a tendency to nose duplication (flatted large nose, 2 columellae, 2 lateral nostrils separated in the midline by a third deformed hole), two mouths and a duplicated maxilla. Laboratory tests were normal. The cranio-facial CT confirmed the maxillary duplication.
  
  
  CONCLUSIONS
  This type of cranio-facial duplication is a rare entity with about 35 reported cases in the literature. Our patient was similar to a rare case of living diprosopus reported by Stiehm in 1972. Diprosopus is often associated with abnormalities of the gastrointestinal tract, the central nervous system, the cardiovascular and respiratory systems and with a high incidence of cleft lip and palate. Surgical treatment consists in the resection of the duplicated components.
