What condition is characterized by a young male experiencing unilateral nasal obstruction, nasal discharge with a foul smell, and difficult-to-control nosebleeds?

The condition characterized by a young male experiencing unilateral nasal obstruction, nasal discharge with a foul smell, and difficult-to-control nosebleeds is juvenile nasopharyngeal angiofibroma. This is a benign vascular tumor that typically occurs in adolescent males, and its presentation aligns well with the symptoms described.

Unilateral nasal obstruction is a common symptom due to the growth of the tumor within the nasal cavity or nasopharynx, leading to blockage. The foul-smelling nasal discharge is likely due to necrotic tissue or secondary infection, which can occur with this type of lesion. Additionally, the difficulty controlling nosebleeds is attributed to the highly vascular nature of the tumor; it can engorge blood vessels in the area, leading to significant epistaxis (nosebleeds).

In contrast, other conditions mentioned do not have the same profile. Allergic rhinitis typically presents with bilateral symptoms and is associated with clear nasal discharge rather than foul-smelling discharge. Sinonasal papilloma, while it can cause nasal obstruction and bleeding, is less common in adolescent males and typically does not have the distinctive foul smell associated with it. Acute sinusitis may lead to nasal drainage but generally presents with bilateral symptoms and does not singularly account for the characteristic sign
