A brief insight regarding Nasopalatine duct cyst – Report of a case with a review of literature

Abstract

Nasopalatine duct cysts (NPDCs) are among the most common non-odontogenic cysts, typically located in the midline of the anterior hard palate. They arise from the embryonic epithelial remnants of the nasopalatine duct. NPDCs are more frequently seen in adult males, usually during the fourth decade of life. Clinically, they present as an asymptomatic or occasionally painful, fluctuant, or discharging swelling in the hard palate. Radiographically, NPDCs appear as well-defined, corticated, inverted pear-shaped or heart-shaped radiolucencies situated between the roots of the maxillary incisors. Histologically, the epithelial lining shows considerable variation, ranging from stratified squamous to pseudostratified ciliated columnar, columnar, or cuboidal epithelium, with transitions often observed between these types. The cyst wall is fibrocollagenous and may include distinctive features such as neurovascular bundles, mucous glands, or cartilaginous remnants. Management typically involves surgical enucleation, with a low risk of recurrence. Here, we present a case of NPDC along with a brief overview of its origin, diagnostic characteristics, and treatment approach.
