Mediastinal lymphadenitis symptoms?

summary

Lymphadenitis is caused by bacteria invading lymph nodes along lymphatic vessels. But not everyone will encounter bacterial infection lymphadenitis, only in the human body resistance decline, it is easy to occur this disease. When the long-term malnutrition, anemia and other chronic diseases make the resistance decreased significantly, lymphadenitis is easy to occur after bacterial infection. Staphylococcus aureus and Streptococcus haemolyticus are the main bacteria causing the disease.

Mediastinal lymphadenitis symptoms?

Benign enlargement, such as reactive hyperplasia of lymph nodes or nonspecific lymphadenitis: including enlargement caused by various infections, connective tissue diseases and allergic reactions. Clinical often showed a benign process, with the etiology removed, in a certain period of time can completely recover.

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 the cervical lymph nodes, especially in cervical lymph nodes. There are many reasons for this, including bacteria, viruses, toxins, denatured tissue components and foreign bodies, which can be used as antigens or allergens to stimulate lymphoid tissue reaction. If mammary gland hyperplasia, thyroid tumor can cause cervical or axillary lymph node reactive hyperplasia.

The extent of lymphadenopathy varies, sometimes up to 10 cm. Microscopically, the composition and distribution of reactive hyperplasia of lymph nodes are different due to different pathogenic factors. Reactive hyperplasia of lymph nodes is a benign lesion, but the enlarged lymph nodes are often confused with the tumor of lymph nodes, but the treatment and prognosis are very different, so we should pay attention to the differential diagnosis.

matters needing attention

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.
