Sclerotherapy with monoethanolamine oleate in benign oral vascular lesions.

AIM: The aim of the present study was to carry out a retrospective survey at the Stomatology Clinic of a federal university in Brazil of 411 dental charts for the assessment of vascular tumors. METHODS: After the determination of the sample, the following clinical patient information was recorded: gender, age, ethnic background, marital status, profession, place of birth, clinical diagnosis, anatomic site and tumor size. RESULTS: Among all patients treated, 4.4% had benign vascular tumors in the oral cavity. The majority of these tumors were asymptomatic, with a purplish, bluish or reddish coloration and of variable size. A clinical examination and vitropressure were essential to the diagnosis. The most affected age group was 60 to 75 years. Vascular tumors most often affected white individuals and the female gender. The most common anatomic site was the tongue, followed by the buccal mucosa. Treatment with sclerotherapy proved effective, with complete regression in 94.5% of the tumors. CONCLUSION: The majority of patients demonstrated wholehearted acceptance of the treatment and side effects following the administration of the substance were slight. Sclerotherapy is a simple, low-cost method of safe and easy execution, allowing the elimination of surgical trauma and a lesser risk of hemorrhage.

Nasolabial cyst: 18.5 year experience in a pathology laboratory.

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.
