Nasolabial cyst in buccal mucosa

Abstract

Nasolabial cysts are a rare non-odontogenic, soft-tissue, developmental cyst reported till date in the sublabial area and anterior maxillary region. The cyst is a slowly enlarging asymptomatic swelling and non-painful. The cyst is believed to be associated with remnants of the nasolabial duct. In this report, we report a nasolabial cyst of a 48-year-old man in whom the cyst occurred in the buccal mucosa. To the best of our knowledge, this is the first case of nasolabial cyst occurring entirely in the buccal mucosa without involving vestibule. The etiopathogenesis of the cyst is reviewed in light of this case.
