[Unilateral nasopalatine duct cyst , differential diagnosis and treatment plan: a case report]

The Nasopalatine duct cyst is the most common developmental nonodontogenic cyst of the oral cavity, occurring in about 1% of the population. The most common presenting symptoms include swelling of the anterior palate, drainage and pain. Occasionally, this cyst is seen unilaterally. Nasopalatine duct cysts are treated by surgical enucleation. Recurrence and malignant transformations are rare. We reported a 54 y/o male patient from Tabriz. His chief complaint was unilateral swelling of the anterior right side of the maxillary mucosa. In clinical examination, a slight and painless swelling in the region of the right maxillary central, lateral and canine teeth was seen. Occlusal radiographs demonstrated well defined unilocular radiolucency. Final histopathologic diagnosis was "Nasopalatine duct cyst"
