Abstract
A 62-year-old male patient showed a purplish swelling in the anterior hard palate midline, measuring 1.5 cm, with pain and 40 days of evolution. CT showed a hypodense unilocular area in the incisive foramen region. A 25-year-old male patient presented a swelling in the central hard palate, with pain and 3 weeks of evolution. Radiography showed a unilocular radiolucent area with 2 cm in the anterior maxilla. In both cases, the related teeth responded to the vitality tests, the diagnosis hypothesis of nasopalatine duct cyst was proposed and needle aspiration reveals a translucent liquid. The treatment of both was surgical excision with full palatal flap and curettage. Histopathologic examination showed, in both cases, cystic capsule of fibrous connective tissue, with neurovascular bundle, lined by stratified squamous and cuboidal epithelium, establishing the diagnosis of nasopalatine duct cyst. Both patients were followed-up for 18 months with no signs of recurrence.
