  1. 1. BIOLOGY 120 Author: Jason GodoChapter 6 Presentation
  2. 2.  Hodgkin disease is a type of lymphoma. Lymphoma is cancer of lymph tissue found in the lymph nodes, spleen, liver, and bone marrow. The first sign of Hodgkin disease is often an enlarged lymph node. The disease can spread to nearby lymph nodes. Later it may spread to the lungs, liver or bone marrow. The cause is unknown.
  3. 3.  Hodgkindisease is rare. Symptoms include:  painless swelling of the lymph nodes in the neck, armpits, or groin  fever and chills  night sweats  weight loss  loss of appetite  itchy skin
  4. 4.  Hodgkin’s disease can be diagnosed with a biopsy.  This involves removing and examining a piece of tissue under a microscope.  Treatment varies depending on how far the disease has spread and often includes radiation theraphy or chemotherapy. The earlier the disease is diagnosed, the more effective the treatment. In most cases, Hodgkin disease can be cured.
  5. 5.  Kaposis sarcoma is a disease in which cancer cells are found in the tissues under the skin or mucous membranes that line the mouth, nose, and other organs. KS causes red or purple patches (lesions) on the skin and/or mucous membranes and spreads to other organs in the body, such as the lungs, liver, or intestinal tract.
  6. 6.  KStumors are divided into three groups, based on appearance, with much overlap. Nodular lesions are of varying size and thickness. They are purple and will at times have a halo of brown or yellow pigment around them. Infiltrating lesions may be quite large, may be raised, or grow downward beneath the skin. Lymphatic lesions can mimic other causes of swollen lymph nodes and may require a biopsy to rule out infection.
  7. 7.  Once the disease occurs, symptoms relate to the site of involvement. Early and more advanced skin lesions are usually only mildly uncomfortable, although painful ulcers may occur. Lesions in the gastrointestinal tract are very common but rarely cause significant symptoms. Early lesions in the lung have no symptoms either, but severe lung involvement produces a profound air hunger.
  8. 8.  KS is not considered curable. Long-term survival does occur both with or without treatment, however. Survival in classic KS is usually years and sometimes decades. All forms of KS are sensitive to radiation theraphy. Radiation is especially useful for lesions that are cosmetically disturbing, painful, involve the mouth extensively, block lymphatics, bleed, or protrude from the skin. Chemotherapy and biological therapy are also utilized in treatment.
  9. 9.  Sarcoidosis is an inflammatory disease. It starts as tiny, grain-like lumps called granulomas, which most often appear in your lungs or lymph nodes. They can clump together and form larger lumps that attack other organs. Sarcoidosis often affects your skin, eyes or liver.
  10. 10.  It does not always cause symptoms, so you can have it without knowing it. No one is sure what causes sarcoidosis. General symptoms caused by the disease include fever, tiredness or fatigue, weight loss, night sweats and an overall feeling of ill health. Some organs are affected more often than others.  Sarcoidosis occurs most often in the lungs.  It also commonly affects the skin, eyes, lymph nodes and liver.  Less commonly, it affects the spleen, brain, nerves, heart, tear glands, salivary glands, sinuses, bones and joints.  Rarely, it affects other organs, such as the kidneys, breasts and male and female reproductive organs. Sarcoidosis may be mild, or it can be severe and do lasting damage.
  11. 11.  The majority of people with sarcoidosis recover without any treatment. It is indicated to follow a treatment according to the disease and the risks incurred by the affected organ. The purpose of the sarcoidosis treatment is to slow or even stop the formation of granulomas and alleviate the various symptoms. The various drugs used for this purpose are from different classes:  Corticosteroids (anti-inflammatory cortisone type)  Cytotoxic agents  Immunomodulators (treatment that stimulates or inhibits the response of the immune system)  Some antibiotics
