Juvenile angiofibromas (JNA) are common benign tumors usually occurring in the nasopharynx of male adolescents. They represent 0.5% of head and neck neoplasms and very rarely they localize in extra-nasopharyngeal sites. Extra-nasopharyngeal angiofibroma (ENPA) is histologically similar to JNA. Due to its clinical and epidemiological characteristics, some authors identify the ENPA as a different disease from the typical JNA. Less than a hundred cases of ENPA are reported in literature. Maxillary and ethmoid sinus are the most commonly involved sites, whereas other localizations such as nasal septum and inferior turbinate are infrequent. We report the case of a ENPA arising from the lateral crus of the alar cartilage, the first described in literature, at the best of our knowledges.

Abstract
Juvenile angiofibromas (JNA) are common benign tumors usually occurring in the nasopharynx of male adolescents. They represent 0.5% of head and neck neoplasms and very rarely they localize in extra-nasopharyngeal sites. Extra-nasopharyngeal angiofibroma (ENPA) is histologically similar to JNA. Due to its clinical and epidemiological characteristics, some authors identify the ENPA as a different disease from the typical JNA. Less than a hundred cases of ENPA are reported in literature. Maxillary and ethmoid sinus are the most commonly involved sites, whereas other localizations such as nasal septum and inferior turbinate are infrequent. We report the case of a ENPA arising from the lateral crus of the alar cartilage, the first described in literature, at the best of our knowledges.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
