Where are the lymph nodes in the neck located?

Clinically, superficial lymph node enlargement is very common. In normal people, lymph nodes can sometimes be palpable in the neck (including the submandibular), armpit, and groin, but normal lymph nodes are soft in texture, smooth in surface, without tenderness, and can slide. The diameter is generally below 0.5cm,

Generally, about 2 lymph nodes can be palpated in the neck, and 1 or 2 lymph nodes can be palpated in the neck. When judging the nature of lymphadenopathy, it is necessary to observe dynamically and pay attention to changes in lymph nodes over a period of time, otherwise it is easy to miss and misdiagnose some early lesions, especially cervical lymphadenopathy, which is the most common and important part of regional lymph nodes. The following reasons:

(1) Acute and chronic inflammation: the most common are tonsillitis, gingivitis, pharyngitis, otitis media and other inflammations,

The cervical lymph nodes are moderately swollen, soft in texture, without adhesion or fusion, and may have pain and tenderness in the acute stage. Generally, the primary lesion can be found, and it can be reduced after treatment with sensitive antibiotics.

(2) Lymph nodes: The most common locations of cervical lymph nodes are the submandibular and the anterior triangle of the neck along the front of the sternocleidomastoid muscle. In the early stage, a cluster of lymph nodes was swollen, which could occur in clusters or sporadically without adhesion. If it deteriorates, the lymph nodes will continue to enlarge, and they can adhere and fuse. Later, they can liquefy, rupture, and flow out of a cheese-like substance. At this time, most of them are accompanied by symptoms of tuberculosis toxicity, which can be reduced and disappeared after anti-tuberculosis treatment.

(3) Lymph node metastasis or malignant lymphoma: nasopharyngeal cancer, oral cancer (lip, tongue, cheek or gum cancer), maxillary sinus cancer, thyroid cancer, and throat cancer may have cervical lymph node metastasis; left supraclavicular lymph node swollen Large, more common in gastric cancer, liver cancer, pancreatic cancer, colon or rectal cancer metastasis; right supraclavicular lymph node enlargement, mostly bronchial lung cancer and esophageal cancer metastasis; malignant lymphoma also occurs in cervical lymph nodes. The lymph nodes are hard in texture, with unclear borders, no pain, and no tenderness. They can adhere to the skin and other tissues, be fixed, and fuse with each other. With the development of the disease, the number and number of lymph nodes increase progressively.

Regarding the location of cervical lymph nodes, in summary, when cervical lymph nodes are swollen, you should go to the hospital in time, especially if the antibiotic treatment is ineffective, you should actively search for the cause, and perform a lymph node biopsy if necessary, and make a diagnosis as soon as possible. Targeted treatment. Special attention should be paid to nasopharyngeal cancer, which is known as "Guangdong Cancer". The annual incidence is the highest in the Pearl River Delta of Guangdong and the Xijiang River Basin in Guangdong and Guangxi: 58.6/100,000 males and 22.8/100,000 females, accounting for the first malignant tumor , the cervical lymph node metastasis rate is high, 40% of the first symptoms of neck mass, and 60-80% of the mass in the upper neck at the initial diagnosis, the disease is more sensitive to radiotherapy and chemotherapy, early detection and early treatment effect is good, Do not carelessly delay the time for treatment.
