Two cases of nasoalveolar cysts presenting with characteristic clinical features are reported.
A 42-year-old woman was referred to our hospital because of upper lip swelling by her dentist. A computed tomographic (CT) scan revealed bilateral nasoalveolar cysts.
A 50-year-old woman was referred to our hospital because of a swelling at the right nasal ala with epiphora by her dentist. A CT scan revealed a right-side nasoalveolar cyst, possibly developing from the nasolacrimal duct. Both cysts were removed surgically under general anesthesia, and they adhered to the nasal mucous membrane.
Histopathological examination revealed that the cyst walls consisted of columnar epithelium with goblet cells and fibrous connective tissue with minor glands.
