Testosterone and estradiol in juvenile nasopharyngeal angiofibroma tissue.
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.
