Nasal polyps are a type of benign neoplasm in the nasal cavity, appearing as half a lychee, translucent, and either oval or ovoid in shape. They occupy the normal passages of the nasal cavity, causing symptoms such as nasal congestion, and even headaches in the head or forehead area. Nasal polyps are benign neoplasms and rarely develop into malignant lesions. Clinically, there have been no cases seen where nasal polyps have turned malignant. Some growths that look like nasal polyps may actually be nasal papillomas, which are more prone to malignancy. Therefore, it is recommended that patients with nasal polyps undergo early surgical intervention followed by a pathological examination to differentiate them from nasal papillomas and to assess the prognosis of the condition.
