Spontaneous Involution of Juvenile Nasopharyngeal Angiofibromas: Report of a Case.

Juvenile nasopharyngeal angiofibroma (JNA) is a locally aggressive tumor that predominantly affects adolescent males. Surgical resection is generally considered the standard treatment for both primary and recurrent tumors, regardless of staging. The natural history of these tumors, particularly when untreated or in the setting of residual tumor, is not well characterized. In this article, we report a case of true spontaneous JNA involution. Although the involution of residual tumor after surgical resection has previously been reported, to our knowledge, this is the first documented case of spontaneous JNA involution following a period of tumor growth post-treatment.
