title: Retrospective analysis of 15 cases of nasolabial cyst.
abstract: The nasolabial cyst is classified as a nonodontogenic cyst and is the only nonodontogenic cyst to occur in soft tissue. The aim of this retrospective analysis was to gather demographic, clinical, radiographic, and histopathologic data on the nasolabial cysts described in the files of the Oral Pathology Laboratory of Minas Gerais University School of Dentistry. Fifteen cases were included in the analysis. The mean age of the patients at the time of diagnosis was 42 years, and there was a female predilection. All the cysts were asymptomatic. Pseudostratified columnar (respiratory) epithelium, alone or in combination with other types of epithelium, was present in all cysts. Recurrence was not observed after surgical excision.
