Bilateral Frontal Sinus Ectopic Angiofibroma: Focus on Management of a Rare Lesion with Unusual Presentation

Extranasopharyngeal Angiofibromas (ENA) are rare benign tumors originating in the majority of cases from the nasal septum, while involvement of the frontal sinus is extremely rare, with few cases reported in literature. ENA present the same histological characteristics and immunophenotype of Nasopharyngeal Angiofibromas (NA), which are more commonly found; however, they do not present the typical clinical presentation of their nasopharyngeal counterpart, therefore biopsy is mandatory to obtain the diagnosis.
