A swelling seen in the posterior nasal cavity is not necessarily a papilloma. The masses that can be observed in the posterior part of the nasal cavity include papilloma, posterior nostril polyp, nasopharyngeal fibroangioma, etc.
1. Papilloma: mostly refers to inverted papilloma, related to human papilloma virus infection. Nasal and sinus inverted papilloma occurs in the lateral wall of nasal cavity, the tumor body is large, soft, red, often multiple, diffuse growth, the appearance of lobulated or papillary, with a tip or wide base. Examination shows that the appearance is polypoid or lobulated, pink or gray-red, the surface is uneven and bleeds easily when touched.
2. Posterior nostril polyp: caused by allergy, infection and “immobile cilia syndrome”, causing hypertrophy and extreme edema of nasal cavity and sinus mucosa. During nasopharyngoscopy, smooth surface, grayish-white, translucent new organisms, mostly single, are often found in one side of the posterior nostril. The slender, smooth, grayish-white tip can be seen in the middle nasal passage after careful contraction of the nasal cavity.
3. Nasopharyngeal fibrous hemangioma: the tumor mostly originates from the base of the pterygoid bone or occipital bone of nasopharynx, the periosteum of the plough bone, which is the result of irregular development of the skull base in puberty. Nasopharyngoscopy shows that there are smooth round or nodular tumors in the nasopharynx with reddish color and obvious vascular lines on the surface. It bleeds easily when touched.
When a tumor is found in the nasal cavity and larynx during examination, it is necessary to complete the relevant examinations and seek the opinion of a specialist to fully understand the nature and characteristics of the disease and to clarify the type and extent of the disease.
