A RETROSPECTIVE ANALYSIS OF 597 ORAL VASCULAR ANOMALIES DIAGNOSED IN A BRAZILIAN POPULATION

Objective To perform an oral vascular anomalies (OVAs) retrospective analysis in a Brazilian population, in order to investigate its frequency distribution, demographic peculiarities and clinical-pathology characteristics. Study Design Data about the sex, age, race, clinical characteristics, location, and histopathologic diagnosis were extracted from cases recorded as OVAs in a reference center in the period between 1970 and 2016. Then, a database was created for analysis in the SPSS 20.0 system, in which they were submitted to a descriptive analysis. Results A total of 14,560 records were analyzed, of which 597 cases were histologically confirmed as OVA, indicating a 4.1% incidence. The lesions were grouped as the following: pyogenic granuloma (n = 454), hemangioma of childhood (n = 57), vascular malformation (n = 37), lymphangioma (n = 20), hemangiolymphangioma (n = 10), vascular thrombus (n = 7), hemangioendothelioma (n = 5), Kaposi sarcoma (n = 5), angiofibroma (n = 1), and hemangioendotheliosarcoma (n = 1). The patients’ sociodemographic profile was predominantly women (64.2%) and white people (48.2%), with a greater occurrence between the second and fourth decades of life. The majority was located in the gingiva or alveolar ridge (42.9%), presenting a red color (50.9%), sessile implantation (42%), soft consistency (44.5%), nodular appearance (38.3%), nonhemorrhagic (42.9%), and asymptomatic (32.8%). Conclusions These lesions particularities knowledge is important for a correct diagnosis and adequate treatment decision.
