title: Juvenile nasopharyngeal angiofibroma. An unusual presentation as an oral mass.
abstract: Although juvenile nasopharyngeal angiofibroma (JNAF) usually presents as a mass in the nasopharynx, the primary manifestation may, in rare instances, occur intraorally. We observed such a case in a 12-year-old boy. The clinical finding of hemorrhage from the nasopharynx or contiguous areas in a male adolescent is an important diagnostic clue which should alert the clinician to the possibility of JNAF as the underlying cause.
