Most nasopharyngeal masses are benign, and very few are malignant tumors. Symptoms of benign masses include the following categories: 1. nasopharyngeal fibrovascular tumors: adolescent hemorrhagic fibrovascular tumors, mainly manifesting as bleeding and nasal congestion; 2. adenoidal hypertrophy: most often found in adolescents, which is easily misdiagnosed as nasopharyngeal cancer and therefore requires biopsy to confirm the diagnosis; 3. nasopharyngeal tuberculosis: symptoms are atypical, such as nasal congestion or blood in the nose, often combined with systemic tuberculosis symptoms, such as low fever, night sweats, and wasting; 4. nasopharyngitis: inflammation of the mucous membrane of the nasopharynx.
