Please DO NOT add profiles to this project. It is for general info.
The lymphatic system consists of a network of hollow tubes that carry a protein-rich fluid called lymph. This system also includes lymph nodes, clusters of immune system cells that protect the body from infections. In addition to its protective role, the lymphatic system is essential for returning vital proteins and fluid to the bloodstream. Many types of diseases can affect the lymphatic system, but obstructive conditions, infections and cancer are the most common. Rarely, structural or functional problems may arise.
Lymphatic disease is a class of disorders, which directly affect the components of the lymphatic system.
Examples include Castleman's disease[1] and lymphedema.[2]
Diseases and disorder Hodgkin's Disease/Hodgkin's Lymphoma
- This is a type of cancer of the lymphatic system. It can start almost any where in the body. It's believed to be caused by HIV, Epstein-Barr Syndrome, age and family history. Symptoms include weight loss, fever, swollen lymph nodes, night sweats, itchy skin, fatigue, chest pain, coughing and/or trouble swallowing.
Non-Hodgkin's Lymphoma
- Lymphoma is a usually malignant cancer. It's caused by the body producing too many abnormal white blood cells. It is not the same as Hodgkin's Disease. Symptoms usually include painless, enlarged lymph node or nodes in the neck, weakness, fever, weight loss, and anemia.
Lymphadenitis is an infection of the lymph nodes usually caused by a virus, bacteria or fungi. Symptoms include redness and/or swelling around the lymph node.
Lymphangitis
- Lymphangitis is an inflammation of the lymph vessels. Symptoms usually include swelling, redness, warmth, pain and/or red streaking around the affected area.
Lymphedema
- Lymphedema is the chronic pooling of lymph fluid in the tissue. It usually starts in the feet or lower legs. It's also a side-effect of some surgical procedures.
Lymphocytosis
- Lymphocytosis is a high lymphocyte count. It can be caused by an infection, blood cancer, lymphoma, or autoimmune disorders that are accompanied by chronic swelling.
