Abstract:
Five cases of juvenile nasopharyngeal angiofibroma (JNA) were studied in terms of the presence of testosterone and estradiol in the JNA tissues using the peroxidase-antiperoxidase method. Testosterone was found to be negative and estradiol positive in all cases. JNA is considered to be a tumor associated with estradiol.
