Chapter 19; Diseases of the Lymphatic System

Hodgkin's lymphoma

B-cells should produce antibodies that guide the immune system in defense of invading bacteria, but Reed-Sternberg cells are a malignant, nonfunctional form of B lymphocyte. Chemotherapy and radiation therapy are the two main methods of treating this. Complications due to this include pain after drinking alcohol, night sweats, loss of appetite, weight loss, fever, and general itching over the entire body.

e

_____ may occur in cases of sickle cell anemia

splenomegaly

Four postmortem conditions

1. Edema 2. Emaciation 3. Dehydration 4. Metastasis

Lymphoma

A cancer of the lymphatic system, causing some of the cells in the lymphatic system to grow abnormally and out of control. Because there is lymph tissue throughout the body, the cancer cells may spread to other organs, or even into the bone marrow. There are two broad categories of lymphoma known as Hodgkin's lymphoma and non-Hodgkin's lymphoma.

Non-Hodgkin's lymphoma

All lymphomas that are not Hodgkin's lymphomas are A collection of many varied lymphoma Most arise within a lymph node, but some arise in areas other than nodes, such as the jaw or brain.

Lymphangitis

An inflammatory disorder of the lymph vessels, characterized by local and systemic pain. It commonly results from a bacterial infection of the skin known as cellulitis, or from a skin abscess. Suggests that an infection is progressing, and that bacteria may have migrated to the bloodstream. This fatal condition may be confused with blood clots in the veins of the legs, which is a disorder known as thrombophlebitis. Characteristics are, red streaks extending from the infected area to the axillary space or groin, throbbing pain along the affected area, fever and chills, anorexia, headache, muscle aches

Lymphadenopathy

Enlargement of lymph nodes The increased size is caused by proliferation of lymphocytes and leukocytes within the node or by the presence of a tumor in the node. Most frequently, lymphadenopathy occurs as a result of local, regional, or systemic infections. It can also be due to cancer, inflammation of the thyroid, autoimmune diseases like rheumatoid arthritis, or drug reactions. More common in young children because their immune systems are responding more frequently to newly encountered infections In the U.S. some causes include: infectious mononucleosis, cytomegalovirus infections, upper respiratory infections, and HIV infection. Internationally, it's more commonly due to tuberculosis, typhoid fever, trypanosomiasis, schistosomiasis, and carious fungal infections

Any disorder of the lymphatic system is prone to cause what problems?

Fluid disruptions such as edema and dehydration, which can prevent nutrients from reaching the tissues leading to emaciation

Tonsillitis

Inflammation of the tonsils caused by an infection. The tonsils become enlarged, red, and often spotted or coated by microorganisms, which appear yellow, gray, or white. Can begin as sudden sore throat and painful swallowing; it can progress into severe respiratory difficulties. Healthcare professionals have since discovered the importance of the tonsils in the immune system, and is now treated with antibiotic
