What are the diagnostic methods for rashes on children's necks?

We all know that children have been in a state of continuous development since birth, so many diseases occur slowly. For example, if a child has a pimple on his neck, many parents think it is normal. On the contrary, our necks are full of lymph nodes, which may be lymphomas. In order to confirm the disease, we will explain below the diagnostic methods for pimples on children's necks.

1. Enlargement of lymph nodes in one area is called localized lymphadenopathy, which is often seen in nonspecific lymphadenitis, lymph node tuberculosis and metastasis of malignant tumors. The primary lesion should be found according to the lymphatic drainage area. If lymph nodes are swollen in more than two areas, it should be considered as systemic lymphadenopathy, which is more common in acute and chronic lymphadenitis, infectious mononucleosis, leukemia, lymphoma, leptospirosis, scrub typhus, brucellosis, serum sickness, connective tissue disease, etc.

2. Associated symptoms can provide important clues to the cause of swollen lymph nodes.

(1) Patients with swollen lymph nodes accompanied by infection foci in the corresponding drainage areas, such as swollen submandibular and submental lymph nodes accompanied by tonsillitis and gingivitis, swollen axillary lymph nodes accompanied by mastitis, swollen postauricular lymph nodes accompanied by scalp infection, and swollen left inguinal lymph nodes accompanied by erysipelas of the left lower limb, can be diagnosed with nonspecific lymphadenitis.

(2) Lymph node enlargement accompanied by pain is usually caused by acute inflammation, often with local redness, swelling, heat and other inflammatory manifestations; while painless lymph node enlargement is common in malignant tumor metastasis, lymphoma, etc. Local lymph node enlargement accompanied by low fever, night sweats, and weight loss may indicate lymph node tuberculosis, malignant lymphoma, or other malignant tumors.

(3) Lymph node enlargement accompanied by periodic fever is often seen in malignant lymphoma; systemic lymph node enlargement accompanied by fever is seen in infectious mononucleosis, leukemia, lymphoma, etc., and occasionally in systemic lupus erythematosus.

(4) Lymph node enlargement accompanied by rash is often seen in certain infectious diseases or allergic diseases, and one should also be alert to lymphoma.

Children are a vulnerable group, especially babies. They cannot speak, and even if they feel pain, they cannot express it. Therefore, it is entirely up to their parents to discover it visually. If your child has a lump on his neck, you need to go to the hospital for diagnosis in time. The development of children is different from that of adults. Finally, I hope that every child can have a healthy and happy childhood.
