EXTENSIVE NASOPALATINE DUCT CYST: A CASE REPORT

Nasopalatine duct cyst (NDC) is a development originating from epithelial remnants of the nasopalatine duct. NDC has a slow growth and is usually asymptomatic. The aim of this study is to describe a case of NDC in a 26-year-old male who presented with swelling in the anterior palate measuring approximately 2.5 cm on its longest diameter. Tomographic examination showed a unilocular, well-defined radiolucency with sclerotic border located between the maxillary central incisors roots. The microscopic examination revealed fragments of cystic capsule lined by a thin stratified squamous epithelium in combination with simple columnar and pseudostratified ciliated columnar epithelium. The diagnosis of NDC was made. The lesion was surgically removed by enucleation. The patient remains under follow-up.
