NC usually presents as an asymptomatic swelling located in the anterior region of the maxilla lateral to midline\u2014resulting in obliteration of nasolabial sulcus, nasal vestibule and maxillary labial sulcus and facial asymmetry\u2014often observed on early stages by most patients due to cosmetics issues.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case report<\/jats:title><jats:p>A 76\u2010year\u2010old woman was referred for evaluation of an asymptomatic facial swelling in the left upper lip region lasting 20\u00a0years. Extraoral clinical examination showed a left\u2010sided swelling lateral to midline near to the alar base resulting in facial asymmetry. Intraoral clinical examination revealed the presence of a single painless well\u2010defined nodular, sessile, non\u2010tender swelling covered by normal oral mucosa, and located in the upper labial mucosa in the left incisor's region. An excisional biopsy was performed, and microscopic examination revealed a cystic cavity lined by cuboidal to columnar epithelium with mucous cells. The underlying connective tissue showed chronic inflammatory infiltrate close to muscular tissue.
