Lymphangitis is an inflammation of the lymph vessels. Symptoms usually include swelling, redness, warmth, pain or red streaking around the affected area. [citation needed] Lymphedema. Lymphedema is the chronic pooling of lymph fluid in the tissue. Lymphedema can start anywhere in the lymphatic system of the body.
Lymphoid tissue associated with the lymphatic system is concerned with immune functions in defending the body against infections and the spread of tumours. It consists of connective tissue formed of reticular fibers , with various types of leukocytes (white blood cells), mostly lymphocytes enmeshed in it, through which the lymph passes. [ 37 ]
Mucosa-associated lymphatic tissue lymphoma: 31339: Mucosa-associated lymphatic tissue lymphoma (as known as MALT lymphoma and extra-nodal marginal zone lymphoma) is a condition in which lymphatic tissue abnormally presents outside the lymphatic system (extra-nodular) and instead within the mucosa of the gastrointestinal tract, typically as a ...
The lymphatic system functions as a critical portion of the body's immune system and returns interstitial fluid to the bloodstream. Lymphedema is most frequently a complication of cancer treatment or parasitic infections, but it can also be seen in a number of genetic disorders. Tissues with lymphedema are at high risk of infection because the ...
Epstein–Barr virus–associated lymphoproliferative diseases (also abbreviated EBV-associated lymphoproliferative diseases or EBV+ LPD) are a group of disorders in which one or more types of lymphoid cells (a type of white blood cell), i.e. B cells, T cells, NK cells, and histiocytic-dendritic cells, are infected with the Epstein–Barr virus (EBV).
In this staging system, stage I represents localized disease contained within a lymph node group, II represents the presence of lymphoma in two or more lymph nodes groups, III represents spread of the lymphoma to lymph nodes groups on both sides of the diaphragm, and IV indicates spread to tissue outside the lymphatic system. Different suffixes ...
[1] [2] Because these tissues are all intimately connected through both the circulatory system and the immune system, a disease affecting one will often affect the others as well, making aplasia, myeloproliferation and lymphoproliferation (and thus the leukemias and the lymphomas) closely related and often overlapping problems.
Lymphohemangioma is a disease characterized by swelling of the lymph nodes and blood vessels.It is variously described as a "mixture of clear fluid and blood-filled cysts", [citation needed] a mass of abnormal swollen veins and lymph nodes, or a tumorous growth of lymph and blood vessels.
