I. Adenoid proliferation The differential diagnosis of nasopharyngeal carcinoma begins with the addition of adenoids, as this condition is commonly seen in young children and adolescents with adenoid bodies. Top of nasopharynx. When the pharyngeal tonsils are enlarged and the mucosa is normal, when there is a high degree of proliferation or surface ulceration or granuloma-like formation, cancer is noted and should be biopsied. Secondly, the symptoms of nasopharyngeal cancer include inflammation of nasopharyngeal cancer in time. According to experts, the mucous membrane is often rough, there are many secretions, the surface is uneven, and most of the follicles proliferate into nodules of 0.2 to 0.3 cm in size, which are purple-red and sometimes orange-yellow, often accompanied by nasal mucositis, laryngitis, paranasal sinusitis and lymphatic tissue proliferation in the posterior pharyngeal wall in the form of small nodules. The nasopharyngeal tumor can be treated by clearing heat, promoting pharynx, activating blood circulation and removing blood stasis. Secondly, benign nasopharyngeal tumors can also be found in the symptoms of nasopharyngeal cancer. Experts say that because these tumors are rare, have a long course and are usually found in the anterior part of the neck, they are round and elevated or lobulated with smooth surface. Such as fibroids, fibrovascular tumors, mixed tumors, chordoma, etc. Differential diagnosis of nasopharyngeal carcinoma? If acute lymphadenitis is caused by general pathogenic bacteria, there are mostly redness, swelling, heat, pain, increased local temperature, often accompanied by oral and pharyngeal infections, increased white blood cell count, high neutrophils, mild or moderate enlargement of lymph nodes, smooth, soft and active, obvious tenderness, clear borders, and effective anti-inflammatory treatment. Chronic non-specific lymphadenitis, enlarged lymph nodes in the neck regardless of bacterial or viral causes, normal local skin color, and low body temperature. Tenderness is not obvious. They are often the size of soybeans or fava beans. They are smooth, tough, active, and have clear sides, often changing with the severity of inflammation in the pharynx, oral cavity, and ears, and anti-inflammatory treatment is not satisfactory. V. Nasopharyngeal tuberculosis is rare, mostly with nasopharyngeal discomfort and foreign body sensation. Increased secretion, often accompanied by tuberculosis of other organs, such as pulmonary tuberculosis. Malignant lymphoma has an acute onset and a short course, mostly in adolescents, the lesion can involve the entire nasopharyngeal cavity, commonly bilateral or other lymph nodes are generally enlarged, the texture is softer than metastatic lymph nodes, there is a sense of elasticity, the clinical often need to make a pathological examination for differential diagnosis.
