Nasolabial cyst in an elderly patient: A case report

Abstract

Nasolabial cyst (NC) or Klestadt's cyst is a relatively rare soft tissue developmental cyst occurring in the nasolabial fold, accounting for approximately 0.7% of all non-odontogenic cysts. [1][2][3] The pathogenesis of NC remains unknown, but has been attributed to epithelial remnants retained in the nasolacrimal duct extending between the lateral nasal process and maxillary prominence. [3][4][5][6] Clinically, NC presents as an asymptomatic soft swelling in the upper labial mucosa in the area of the nasolabial fold, which may cause facial asymmetry. [1][2][3][4][5][6] Pain may be experienced by patients with secondary infection due to nasal obstruction induced by the cyst. 4,5 The condition has a predilection for females, and most patients are in the fourth to fifth decades of life. NC usually appears as a solitary lesion but 10% of cases may occur bilaterally. 7 Panoramic and intraoral radiographs usually do not reveal

Nasopalatine Duct Cyst with Impacted Inverted Mesiodens: A Rare Case Report and Literature Review

“…Inflammatory lesions, such as periapical cysts and granulomas [ 37 , 40 , 41 , 44 , 46 ], wide IF [ 9 , 36 , 37 , 41 , 44 – 46 ], odontogenic keratocyst [ 40 ], nasolabial cyst [ 40 , 47 ], and adenomatoid odontogenic tumor [ 48 ], may be given a place in the differential diagnosis of NPDCs. The radiographic appearance of a periapical cyst/granuloma with a maxillary central incisor tooth often simulates that of an asymmetric NPDC.…”

“…Nasolabial cysts are soft tissue cysts and do not exhibit bone involvement, hence not apparent on the radiographic examination. In addition, the nasolabial cysts most commonly occur in the nasolabial sulcus, lateral to the midline [ 40 , 47 ].…”

Dermoid cyst of the upper lip in a pediatric patient: Case Report

“…Clinical differential diagnosis is extensive and includes a spectrum of oral lesions such as odontogenic and non odontogenic cysts and minor salivary gland tumors [10][11][12][13] . These lesions are often detected by the patient or during a routine dental exam, specially once located on the lips.…”

Clinicopathologic features of nasopalatine duct cysts: A retrospective study in two Brazilian oral and maxillofacial pathology referral centers

“…Interestingly, a differential diagnosis frequently considered by clinicians was the nasolabial cyst (NC). Although these lesions may appear in areas adjacent to the bone at the apex of the root of the incisors, just beneath the lip, they are rare in this location ( 15 ). Usually, NCs are often located laterally to the midline in the nasolabial sulcus.…”

“…Usually, NCs are often located laterally to the midline in the nasolabial sulcus. Besides, NCs are soft tissue lesions with no bone involvement, and their visualization is not possible in radiographic exams, unlike the NDC ( 15 ).…”
