This scenario tests recognizing a juvenile nasopharyngeal angiofibroma as the classic cause of recurrent nosebleeds in adolescence. This is a benign but highly vascular tumor that almost always presents in pubertal boys. Its location in the nasopharynx near the sphenopalatine foramen makes bleeding happen readily with minor trauma or even spontaneously, leading to recurrent epistaxis. Patients often have unilateral nasal obstruction as the mass grows, and imaging reveals a vascular nasopharyngeal mass. Because the tumor is so vascular, treatment planning usually includes preoperative embolization followed by surgical removal to minimize bleeding.

Nasal polyps tend to produce chronic nasal obstruction and are more often bilateral, not specifically linked to adolescent males or heavy, recurrent epistaxis. A deviated septum can cause obstruction and sometimes nosebleeds, but it is not characteristically associated with the heavy, recurrent epistaxis seen in this age group. Allergic rhinitis causes itching, sneezing, and congestion, with epistaxis being uncommon and not a defining feature.
