What is a pimple in the armpit skin ?

The lumps in the armpits are most likely lymph nodes. If there are no other symptoms, it should not be a big problem. This condition may be due to chronic inflammation of the lymph nodes themselves, or swollen lymph nodes caused by inflammation in the surrounding areas. In addition, the possibility of lipoma or sebaceous cyst cannot be ruled out. In this case, you can go to the general surgery department of the hospital for diagnosis.

Causes of swollen axillary lymph nodes

1. Bacterial infection

For example, acute inflammation in the mouth, face, etc. often causes swelling of the mandibular lymph nodes. The swollen lymph nodes are soft in texture and have good mobility, and generally return to normal as the inflammation disappears.

2. Viral infection

Measles, infectious mononucleosis, etc. can cause swollen lymph nodes. Sometimes lymphadenopathy has important diagnostic value, such as rubella, which often causes occipital lymphadenopathy.

3. Lymph node tuberculosis

The most common symptoms are enlarged lymph nodes in the neck, some of which may ulcerate and some may not, and it is sometimes difficult to distinguish them from lymphoma clinically. The diagnostic method is to perform lymph node puncture, smear and biopsy multiple times and in multiple locations to find the primary lesion of tuberculosis.

4. Lymph node metastasis

These lymph nodes are hard, painless, and immobile. Moreover, if the patient has gastric cancer or esophageal cancer, small swollen lymph nodes can be felt above the clavicle. Breast cancer patients may have swollen lymph nodes in the armpits.

5. Leukemia

The lymphadenopathy of this disease is systemic, but is most obvious in the neck, armpits, and groin. In addition to swollen lymph nodes, patients also have anemia, persistent fever, and the appearance of a large number of immature cells in the blood and bone marrow.

6. Lymphoma

Lymph node enlargement is more common in the neck. Lymphoma is a tumor that originates in lymph nodes or lymphatic tissue, and there are also some lesions outside the lymph nodes, such as damage to the tonsils, nasopharynx, gastrointestinal tract, spleen, etc.
