A case of anterior maxillary radiolucency.

A 46-year-old woman sought treatment for pain in her maxillary anterior teeth. Physical examination revealed facial tenderness and an expanded anterior maxilla, with palatal swelling in the approximate midline. The lesion had eroded through the midline anterior palate and anterior nasal spine and had shifted the nasal floor in a superior direction. Teeth No. 8-10 tested nonvital to electrical stimulation. The lesion was dissected carefully and lifted off the nasal floor while the patient was under general anesthesia. Histologically, the lesion was cystic with an epithelial lining composed of respiratory and squamous epithelium. As a result, a nasopalatine duct cyst was diagnosed.
