Papillomas are usually benign tumors that are caused by overgrowth of epithelial tissue, resembling papillae, and occur in the nasal cavity, pharynx, esophagus, external auditory canal, and breast. The cause may be due to a variety of factors, such as viral infection, inflammatory stimulation, allergic reactions, and environmental factors. Common papillomas include nasal invagination papilloma, pharyngeal papilloma, external auditory canal papilloma, etc. The specific symptoms of different types of tumors are somewhat different: 1. The tumor usually originates from the sinus mucosa and can gradually spread outside the nasal cavity as well as to the nasopharynx and the mouth. 2. Pharyngeal papilloma: It is commonly found in the palatal arch and tonsils, and can also occur in the aryepiglottic folds and the back of the soft palate. Most patients with small tumor size have no obvious symptoms, usually found during pharyngeal examination, and a few patients may have dryness, itching and foreign body sensation in the pharynx. If the tumor is large, it may be accompanied by symptoms such as swallowing disorder and breathing discomfort. 3. Papilloma of external ear canal: Patients usually have no obvious symptoms in the early stage, but as the tumor grows until it fills the external ear canal, itchiness, hearing loss and obstruction may appear. If infection occurs, it may also manifest as ear pain and pus. Papilloma is a curable disease and treatment is mainly surgical. Patients should avoid spicy and irritating foods and pay attention to nutritional balance.
