Frequent epistaxis in adolescent males is most characteristic of which condition?

• A. Nasal polyps
• B. Juvenile nasopharyngeal angiofibroma
• C. Allergic rhinitis
• D. Deviated septum

Answer: (B)

Frequent nosebleeds in adolescent males point to a vascular tumor that emerges during puberty and tends to be unilateral. This pattern fits juvenile nasopharyngeal angiofibroma: a benign but highly vascular lesion that classically presents in adolescent boys with recurrent unilateral epistaxis and nasal obstruction. The bleeding is often profuse because the tumor’s vessels are engorged and friable, and it can bleed with minimal trauma or nasal instrumentation. The mass typically arises in the posterolateral nasopharynx near the sphenopalatine foramen and may extend into the nasal cavity or sinuses; imaging usually shows a vascular, enhancing mass with possible bone remodeling. Treatment often involves preoperative embolization to reduce blood loss, followed by surgical resection. Other conditions don’t fit this specific pattern as well. Nasal polyps are usually bilateral and associated with chronic rhinitis or cystic fibrosis, causing obstruction and drainage rather than profuse unilateral epistaxis. Allergic rhinitis presents with sneezing, itching, and watery nasal discharge rather than frequent unilateral bleeding. Deviated septum can cause obstruction and sometimes minor bleeding, but it does not characteristically occur in adolescent males with recurrent unilateral epistaxis.
