Abstract
Introduction: The nasolabial cyst is a rare soft tissue lesion, located close to the alar cartilage of the nose. Most are unilateral, prevailing in the female sex, blacks, in the fourth and fifth decades of life. The most common sign is increased area and facial asymmetry. Objective: Report the clinical picture, the findings in imaging exams, diagnosis and surgical treatment of a female patient with nasolabial cyst. Case report: A 35-year-old female patient complained of chronic nasal obstruction on the right. Examination of anterior rhinoscopy and video flexible nasofibroscopy showed bulging of the nasal floor on the right. Computed tomography evidenced the presence of a lesion measuring 1.7 x 1.0 x 1.6 cm, with attenuation of soft parts, with regular contours and defined limits, with slight enhancement to the intravenous contrast medium, located in the right nasolabial recess, associated with discrete bone erosion extending to the corresponding nasal cavity. Surgical excision was performed and the anatomopathological result corresponded to the nasolabial cyst. Final comments: Although it is a rare condition, in cases of unilateral increase in the nasolabial region, with chronic nasal obstruction and facial asymmetry, attention should be paid to the possibility of nasolabial cysts. If the hypothesis is hinted at, imaging tests become essential to establish a diagnosis and subsequently perform surgical treatment.
