Cervical lymph node metastasis

Cervical lymph node metastatic carcinoma accounts for about 3/4 of the total number of malignant tumors in the neck; the incidence of cervical masses is second only to chronic lymphadenitis and thyroid disease. Most of the primary cancerous foci (85%) are in the head and neck, especially the metastases of nasopharyngeal cancer and thyroid cancer. The primary cancerous foci of the supraclavicular fossa metastasis are mostly in the chest and abdomen (including lung, mediastinum, breast, gastrointestinal tract, pancreas, etc.); Occurs in the left supraclavicular fossa. It must be noted that in many patients with head and neck malignancies (such as nasopharyngeal carcinoma and thyroid cancer), metastatic tumors in the lateral region of the neck are often the first major symptoms to appear; on the contrary, the primary cancer is often small. The patient did not feel it himself, and it was difficult to detect even during the examination. Therefore, it is necessary to carry out a thorough and detailed examination to clear the diagnosis.
