What is the differential diagnosis for nasopharyngeal carcinoma? What are the symptoms?

Nasopharyngeal carcinoma often occurs on the top of the posterior wall of the nasopharynx, followed by the side wall, which is very rare on the anterior wall and bottom wall. The general morphology of nasopharyngeal carcinoma is divided into five types: nodular, cauliflower, mucosal, infiltrative and ulcerative.

The identification and diagnosis methods are as follows:

1. Adenoid hyperplasia: Common in children and adolescents with adenoid constitution. The top of the nasopharynx. The pharyngeal tonsils are enlarged, and the mucosa is normal. When highly proliferative or surface ulcers or granulomas form, pay attention to cancer. A biopsy should be performed.

2 Nasopharyngitis: Common symptoms include rough mucosa, abundant secretions, uneven surface, and most follicular proliferation. Nodules of 0.2 to 0.3 cm in size are purple-red, sometimes orange-yellow, and are often accompanied by nasal mucositis, laryngitis, sinusitis and posterior pharyngeal wall lymphoid tissue.

3 Benign nasopharyngeal tumor: rare. Long course of disease, round or lobed in the front of the project, with a smooth surface. Such as fibroma, fibroangioma, mixed tumor, chordoma, etc.

4. Cervical lymphadenitis: If acute lymphadenitis is caused by common pathogenic bacteria, the local temperature will rise, often accompanied by an increase in the number of white blood cells in the oral and pharyngeal infection.

5. Nasopharyngeal tuberculosis is rare, with discomfort and foreign body sensation in the nasopharynx. Increased secretions are often accompanied by tuberculosis of other organs such as pulmonary tuberculosis.

What are the symptoms of nasopharyngeal cancer?

1. Nasal secretions contain blood or blood clots, which is one of the early symptoms.

2. When ear symptoms occur, catarrhal otitis media often occurs when cancer of the lateral wall of the nasopharynx or other parts of the nasopharynx expands, blocks or compresses the Eustachian tube, leading to tinnitus, ear occlusion and hearing loss, or accompanied by tympanic effusion. Conscious ear symptoms account for 16.1%.

3. Cranial nerve symptoms Cancer can invade the skull through the petrosphenoid bone area of ​​the skull base rupture foramen above the pharyngeal recess. Over time, the skull base bones are destroyed and the lesions expand.

4. Cervical lymph node metastasis is usually the first sign discovered by the patient.
