    Study Notes

    The Lymphatic System

    • The lymphatic system is a vital part of the body's immune defense, working alongside the cardiovascular system.
    • It encompasses lymphatic vessels, lymph nodes, tonsils, spleen, thymus, and bone marrow.
    • Lymphatic vessels collect and filter interstitial fluid before returning it to the bloodstream.
    • This process removes excess fluid and cellular debris, especially during inflammation and edema.
    • Lymph nodes serve as filters for lymph, removing pathogens and cellular debris.
    • Lymph primarily drains into the left subclavian vein; the right arm, chest, and cervical region drain into the right subclavian vein.
    • Tonsils are lymphoid tissues in the throat, providing immunity against pathogens entering via the mouth or nose.
    • The spleen filters blood, destroys old red blood cells, and stores white blood cells for immune response.
    • Red bone marrow produces various blood cells, including lymphocytes.
    • B lymphocytes mature in the bone marrow, while T lymphocytes mature in the thymus.
    • The lymphatic system absorbs lipids from the gastrointestinal tract.
    • Gut-associated lymphoid tissue (GALT) and mucosa-associated lymphoid tissue (MALT) line areas exposed to the external environment offering crucial immune protection.

    Lymphoma

    • Lymphoma is a cancer of lymph nodes, characterized by a malignant neoplasm.
    • It broadly categorizes into Hodgkin's lymphoma and non-Hodgkin's lymphoma.
    • Hodgkin's lymphoma typically starts with a painless, enlarged lymph node.
    • This painless swelling is a crucial sign that warrants prompt evaluation.
    • Hodgkin's lymphoma features Reed-Sternberg cells (two-lobed nucleus) in the affected lymph nodes.
    • The cancer predictably spreads through lymph nodes and may involve the spleen.
    • Systemic signs include weight loss, anemia, low-grade fever, night sweats, and persistent fatigue.
    • Management often involves surgery, chemotherapy, and radiation therapy.
    • Hodgkin's lymphoma stages 1-4 are determined by the number and location of affected lymph nodes.

    Hodgkin's Lymphoma Stages

    • Hodgkin's lymphoma starts with a single enlarged lymph node.
    • Stage 1: Involvement of a single lymph node region.
    • Stage 2: Involvement of multiple lymph node regions on the same side of the diaphragm.
    • Stage 3: Involvement of lymph node regions on both sides of the diaphragm.
    • Stage 4: Spread to organs, typically the spleen and liver.

    Non-Hodgkin's Lymphoma

    • Non-Hodgkin's lymphoma, unlike Hodgkin's, has unpredictable spread patterns.
    • It lacks Reed-Sternberg cells, making it distinguishable from Hodgkin's lymphoma.

    Multiple Myeloma

    • Multiple myeloma is a bone marrow cancer impacting plasma cells (a type of B lymphocyte).
    • It's characterized by deep bone pain and lytic lesions (appearing as "moth-eaten" areas on X-rays).
    • Multiple myeloma typically carries a poor prognosis, typically 3-5 years.
    • Metastasis is common, worsening the prognosis.
    • Impaired kidney function can emerge due to plasma cell-related substances accumulating in the blood and potentially leading to chronic kidney failure.

    Lymphedema

    • Lymphedema results from lymphatic vessel blockage.
    • Causes encompass tumors, radiation therapy scarring, or lymph node removal surgery.
    • Swelling, particularly in the limb distal to the blockage, is a common characteristic.
    • Management involves diuretics, compression garments, elevation, lymphatic drainage massage, and avoiding trauma to the affected limb.
    • Elephantiasis (filariasis) is a severe lymphedema form caused by parasitic infection.

    Castleman's Disease

    • Castleman's disease involves non-cancerous lymphoid tissue overgrowth, especially in lymph nodes.
    • It's characterized by enlargement of one or more lymph nodes.
    • It is not considered a neoplastic disease.
