Abstract

A nasolabial cyst is a rare, non-odontogenic cyst that develops within the area adjacent to the ala of the nose around the uppermost portion of the nasolabial crease. The origin of such a cyst is unclear but may be due to developmental problems. Clinical characteristic of asymptomatic nasolabial swelling and radiological findings are important for diagnosis. Treatment is usually surgical resection via a sublabial approach but can also involve incision and drainage or marsupialization. Unlike the typical clinical features reported in other cases, we experienced a case of a giant nasolabial cyst of 4.4 cm in a 56-year-old male with elevation of the nasal cavity base, gingival swelling, and perilesional bony destruction. In this case, we discussed the growth potential of a nasolabial cyst and proper timing of treatment.

• 

  Fig. 1 Preoperative photographs of the patient. A: The right nasolabial fold has partially disappeared due to the swelling of the alar base of nose. B: The upper gingiva around gingivobuccal sulcus is bulged in oral examination.

• 

  Fig. 2 Preoperative CT and MRI findings. A: PNS CT: well defined homogenous cystic lesion (4.4×3.5 cm) and perilesional bony destruction are observed. B: T1 weighted MRI: a cystic lesion with homogenous hypointensity. C: T2 weighted MRI: a cystic lesion with homogenous hyperintensity.

• 

  Fig. 3 Intraoperative finding: a large cystic lesion and perilesional bony destruction are observed.

• 

  Fig. 4 Histologic finding of the lesion. A: Perilesional inflammation and hemorrhage (H&E, ×100). B: The cystic lining is consist of pseudostratified columnar epithelium (H&E, ×400).
