ABSTRACT
AIM: This paper offers a survey of nasolabial cysts diagnosed at the Pathology Laboratory of the Universidade Federal dos Vales do Jequitinhonha e Mucuri (Brazil) over a period of 18.5 years, and a case report. METHODS: A retrospective study was carried out on biopsies performed at the Pathology Laboratory of the UFVJM School of Dentistry between January 1992 and July 2010. RESULTS: Among a total of 2730 histopathological exams of biopsies performed at the UFVJM Pathology Laboratory, 288 (10.54%) were different types of cysts, The prevalence of NLC was 0.29% (8 cases) in relation to the overall sample and 2.43% among all cysts. NLC only occurred in the female gender in the age group spanning from 25 to 62 years (mean: 40.00 years; standard deviation (SD): 13.48 years). The duration of evolution ranged from six to 18 months (mean: 12 months; SD: 3.79 months). The cysts were asymptomatic in 62.5% of cases. Cyst size ranged from 10 to 30 mm (mean: 16.86; SD: 8.00 mm). In six cases (75%), the radiographic exams were consistent with the final diagnosis, whereas there were no records of radiographic images in two cases (25%). Surgical excision was the treatment of choice for all cases. CONCLUSION: The characteristics of NLC, such as location, elevation of the nasal wing, disappearance of the nasolabial sulcus, nasal obstruction, floatation of the cyst and the presence of cystic liquid in the interior, are enough to suggest the diagnosis of this cyst. However, the confirmation of the diagnosis is performed through biopsy and histopathological analysis.

Fibrolipomas are benign mesenchymal neoplasms of the fatty tissue rarely encountered in the oral cavity. They account for around 1% to 5% of all neoplasms affecting the mouth and occur as raised, slow-growing, painless lesions of normal or yellow coloration and uncertain etiology. In contrast, mucus retention cysts are epithelium-lined cavities originated from a salivary gland. They are also raised, asymptomatic, slow-growing lesions, located on the floor of the mouth, buccal mucosa and lips. This article reports a diagnostic and a surgical treatment of a rare fibrolipoma case associated with a mucus retention cyst located in the palate.
