Nasoalveolar cyst has been reported to develop in 2.5% of nonodontogenic cysts, with bilateral cysts in about 10% of patients. We report a case of bilateral nasoaiveolar cyst in a 43-year-old Filipino woman. She complained of swelling without tenderness of the right nasal ala. Computed tomography and magnetic resonance imaging revealed bilateral cystic lesions in the nasal vestibule, and there was no relation to teeth. Under a clinical diagnosis of bilateral nasoalveolar cyst, the bilateral lesions were extirpated with the patient under general anesthesia. Both cysts adhered to the floor of the nasal mucosa, and partial resorption of the alveolar bone was noted. Histopathologically, the walls of both cysts consisted of stratified columnar epithelium with many goblet cells. In addition to this case, we analyzed 85 cases reported in the Japanese literature from 1960 through 2015 and discuss the clinical and histopathological features.
