Nasopharyngeal angiofibroma is a rare benign soft tissue tumor that only affects young guys, with a peak onset age of 15 years. • Histology reveals a highly vascular neoplasm with variable diameter arteries surrounded by a cellular fibrous stroma. The lesion is covered by an intact sinonasal epithelium. Local recurrence occurs in 720% of cases after surgery.
Nasopharyngeal carcinoma is a malignant epithelial tumor that develops in the nasopharynx. Adults may have nasal congestion, hearing loss, or tinnitus. • Incidence varies geographically, with southern China, Thailand, and the Philippines having higher rates. • Strong link between EBV and nutrition. • Histology classifies tumors into three types: non-keratinizing, keratinizing, and basaloid. Radiation therapy is typically used to treat the majority of instances. 5-year survival rate: 60%
