Note: What diseases are easily confused with nasopharyngeal carcinoma?

In recent years, nasopharyngeal carcinoma has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of nasopharyngeal carcinoma, we humans should master the diseases that are easily confused with nasopharyngeal carcinoma:

1. Nasopharyngeal lymphosarcoma

Lymphosarcoma is common in young people. The primary tumor is large and often presents with severe nasal congestion and ear symptoms. The disease causes lymph node metastasis, not only in the neck, but also in many parts of the body. Damage to cranial nerves is not as common as nasopharyngeal carcinoma, and pathological diagnosis is required.

2. Proliferative lesions

Single or multiple nodules are seen on the top, posterior or lateral walls of the nasopharynx. They are like hillocks and are about 0.5 to 1 cm in size. The mucosa on the surface of the nodules is light red and smooth. They mostly occur on the basis of the nasopharyngeal mucosa or adenoids. They can also form epidermoid cysts due to the retention of keratinized epithelium after squamous metaplasia of the mucosal epithelium. Some are caused by the vigorous secretion of mucosal glands, forming retention cysts. When the mucosa on the surface of the nodule appears rough, eroded, ulcerated or bleeding, the possibility of cancer should be considered and a biopsy should be performed to confirm the diagnosis.

3. Nasopharyngeal tuberculosis. Most patients have a history of pulmonary tuberculosis. In addition to nasal obstruction and bloody mucus, they also have low fever, night sweats, and weight loss. Examination shows nasal ulcers, edema, and lighter color. Smears of secretions can reveal acid-fast bacilli, which may be accompanied by cervical lymph node tuberculosis. The lymph nodes are enlarged, bell-shaped, adherent, and non-tender. Cervical lymph node puncture can reveal tuberculosis bacteria. CT tests are strongly positive, and chest X-rays often indicate active tuberculosis foci in the lungs.

4. Pharyngeal mucosal inflammation is manifested by rough mucosa, especially in severe inflammation. The nasopharyngeal mucosal follicles proliferate, the surface is uneven, and may even appear mulberry-like, with purulent secretions on the surface. It often needs to be differentiated from mucosal invasive carcinoma.

5. In allergic rhinitis, the nasopharyngeal mucosa is pale, smooth and edematous.

6. Atrophic rhinitis may cause shallow ulcers in the anterior mucosa of the nasopharyngeal apex, surrounded by purulent secretions, which needs to be differentiated from ulcerative nasopharyngeal carcinoma.

The above are diseases that can be confused with nasopharyngeal cancer.
