These cysts are usually asymptomatic; however they can result in swelling, pain and drainage. The radio logical analysis can reveal a round, oval or heart shaped well-demarcated image, which can be confounding with inflammatory lesions. The aim of this paper is report a clinical case of NPDC in a patient of 33 years old, occurring near a periapical inflammatory lesion.

During clinical examination, it was not possible to detect swelling of the anterior palate and patient didn't complain painful symptoms. Surgical treatment, enucleation, was performed under local anesthesia and there was no post operative complications.

Histological results showed the presence of a cuboidal and respiratory mucosa associated with vessels, nerves and inflammatory cells. The patient's 3 years follow-up was uneventful with subsequent bone regeneration and no sign of the lesion recurrence.

The nasopalatine duct cyst, first described by Meyer in 1914, is classified as the most common non-odontogenic cyst in the oral cavity, originated from epithelial remnants of the nasopalatine duct in association with trigger events such as trauma, infection and spontaneous proliferation6.

In most of the cases these cysts are asymptomatic, thus detected during oral cavity routine examination8, especially after radiologic analysis that shows a well-demarcated radiolucency located in the midline of the maxilla that can be round, oval or heart shaped.
