title: [Nasopalatine duct cyst].
abstract: BACKGROUND
  Nasopalatine duct cyst is a developmental, nonodontogenic cyst of jaw.
  
  
  METHODS
  We presented a 46-year-old male with nasopalatine duct cyst. The clinical examination revealed fluctuant swellings of the anterior palate, without pain, 4-5 cm in diametar. Both radiographs showed the presence of an ovoid radiolucency located in the midline of the maxilla between the roots of central maxillary incisor teeth with peripheral sclerosis, 25 x 35 cm in diametar. Surgical treatment was performed under local anaesthesia (Articainchloridum 4% - 3M ESPE) using a palatine approach. Postoperatively, no paresthesia of the anterior palate in inervation area of nasopalatine nerve was registrated. Pathohistologic findings proved both clinical and radiological diagnosis.
  
  
  CONCLUSIONS
  Nasopalatine duct cyst is a rare lesion which slowly develops. The diagnosis is mainly based on radiography, tooth vitality testing and histologic findings. After a correctly applied clinical diagnosis procedure and surgicel treatment, recurrence is rare.
