Angiofibromas are rare, benign, but locally aggressive vascular tumours which account for 0.05-0.5% of all head and neck neoplasms. The common variant of angiofibromas of head and neck region is Juvenile Nasopharyngeal Angiofibroma (JNAF) which is well published in the literature. Incidence of Extranasopharygeal Angiofibromas (ENAF) is relatively rare and most of the published literature favours maxillary sinus as the most common site. We report a rare clinical entity of ENAF involving the upper lip which is first of its kind in the light of literature review owing to its anatomical location. The present article not only complements a new location of angiofibroma (in the upper lip) but also concretely reinforces the inclusion of angiofibromas in the spectrum of differential diagnosis of soft tissue lesions pertaining to oral cavity.
