Reactive lymph node hyperplasia in children?

summary

Lymph node is an important immune organ. All kinds of injury and stimulation often cause reactive proliferation of lymphocytes and histiocytes in lymph nodes, making lymph nodes swollen, which is called reactive proliferation of lymph nodes. Reactive lymph node hyperplasia in children? Next, I'd like to share my views with you.

Reactive lymph node hyperplasia in children?

The main characteristics of non-specific reactive follicular hyperplasia are enlargement of lymph nodes, hyperplasia of lymph follicles and enlargement of germinal center. The number of lymph follicles increased, not only distributed in the cortex of lymph nodes, but also scattered in the junction of cortex and medulla.

Reactive lymphoid follicular hyperplasia is easy to be confused with follicular lymphoma. In the latter, the structure of lymph nodes is destroyed, the size and shape of follicles are similar, and the boundary is not obvious. The proliferative cells in the follicles were heterotypic, but the types were relatively consistent. There were few mitotic figures. Generally, macrophages phagocytizing foreign bodies were not found. The proliferative lymphocytes were monoclonal; In reactive lymphoid follicular hyperplasia, the proliferative lymphocytes were polyclonal.

Giant lymph node hyperplasia is also known as angiofollicular lymph node hyperplasia or Castleman's disease; Castleman disease）。 This is a special type of lymph node hyperplasia, not a tumor or hamartoma. It can occur at any age.

matters needing attention

The proliferation of lymph node reaction will have a great impact on the daily life of patients, it may also be caused by long-term malnutrition or anemia, or it may lead to the symptoms of low immunity, so the disease should be treated in time.
