Differential diagnosis of nasopharyngeal carcinoma 1) nasopharyngeal hyperplasia
Under normal circumstances the top of the nasopharyngeal adenoids are mostly in the 30-year-old has shrunk before. But some people in the process of shrinking the more serious infections have occurred, resulting in the formation of the uneven local asymmetry nodules, once produced ulcer bleeding biopsy need to be identified.
2) nasopharyngeal tuberculosis
More common in young people, bad health can be formed, superficial anger or granulation-like uplift of War, more than the dirty surface discharge, or even involving the nasopharynx. With particular attention to whether the coexistence of cancer and tuberculosis, and whether the NPC-like reaction caused by tuberculosis.
3) necrotizing granulomatous nasopharyngeal
Primary lesions in the nasal cavity, the middle area on the Proton, showing partial necrosis and granulation tissue and lead to nasal septum and the uplift of the perforation on the Proton. The disease has a special odor, but also have high fever, pathological examination often see chronic inflammatory changes only.
4) nasopharyngeal angiofibroma
More common in young people, men significantly more than women. Nasopharyngeal microscope, tumor surface is smooth, the color is similar to the normal mucosal tissue, and sometimes visible surface blood vessels to expand, touch of quality real tough. Once the disease is suspected and the clinical, biopsy forceps should not lightly to avoid serious bleeding.
Nasopharyngeal carcinoma in the differential diagnosis 5) cervical lymphadenitis
Common, usually located under the collar (caused by the throat or dental disorders). But middle-aged patients or in the deep cervical nerve chain lymph nodes at a hard, it should be immediately removed the possibility of tumor metastasis.
6) cervical lymph node tuberculosis
Adolescents were more common. Hard enlarged lymph nodes, adhesion with the surrounding tissue into pieces, sometimes with a sense of tenderness, or fluctuation, the puncture can be sucked out of dry enzyme-like substance.
7) malignant lymphoma
See more young people, throughout the multiple cervical lymph nodes may also armpits, groin, mediastinum lymph nodes and other areas are also visible. Soft mass, activity.
Differential diagnosis of nasopharyngeal carcinoma, 8) cervical lymph node metastases of other
Department of Otolaryngology and oral cancer can often cervical lymph node metastasis, the sites mostly in the deep cervical, middle and nerve chain lymph nodes. If there is transfer of supraclavicular lymph nodes, the first consideration should be from the chest, abdominal and pelvic malignancies. It should also pay attention to and craniopharyngioma, chordoma, and sphenoid sinus cyst phase identification.
