Nasolabial cysts are rare benign lesions that occur in the nasal alar region. They probably arise either from the anlage of the nasolacrimal duct system or as epithelial inclusion cysts trapped between the merging nasal and maxillary processes of the developing facial skeleton. They has been usually presented as a smooth, mobile, soft tissue mass between the upper lip and nasal aperture, producing protrusion of the upper lip, elevation of the nasal ala and inferior turbinate, effacement of the nasolabial fold. Slow painless enlargement of these lesions may be noted over several years, or they may present with more sudden, painful swelling when infected. The lesions are extraosseous, but scalloping of the underlying bone may be seen. The treatment of choice is surgical resection by intraoral sublabial approach. We report, with a review of literature, a case of nasolabial cyst which involves left alveolus, hard palate and extends into right premaxillary area.
