Abstract Nasopalatine duct cysts (NPDCs) are among the most common nonodontogenic cysts, typically located in the midline of anterior maxillary hard palate. They usually arise from the embryonic epithelial vestiges of the nasopalatine duct. NPDCs predominantly affect adult males, generally during their fourth decade of life. Clinically, they present as asymptomatic or occasionally painful, fluctuant or discharging swellings involving the hard palate. Radiographically, NPDCs are characterized by a well-defined, fairly corticated, inverted pear-shaped or heart-shaped radiolucency situated between the roots of the maxillary incisors. Histopathologically, NPDCs exhibit a wide spectrum of findings. The lining may be comprised of stratified squamous, pseudostratified ciliated columnar, columnar, or cuboidal epithelium, or a combination and transition of these types. The cystic capsule is fibrocollagenous and can exhibit certain unique features, such as neurovascular bundles, mucous glands, and cartilaginous rests. NPDCs are typically managed through surgical enucleation, and recurrences are rare. Herein, we present two cases of NPDCs, along with a brief overview of their origin, relevant diagnostic features, and management.
