Lymphoma

Lymphoma is a cancer of a part of the immune system called the lymph system. There are many types of lymphoma. One type is Hodgkin disease. The rest are called non-Hodgkin lymphomas. Non-Hodgkin lymphomas begin when a type of white blood cell, called a T cell or B cell, becomes abnormal. The cell divides again and again, making more and more abnormal cells. These abnormal cells can spread to almost any other part of the body. Most of the time, doctors don't know why a person gets non-Hodgkin lymphoma. You are at increased risk if you have a weakened immune system or have certain types of infections. Non-Hodgkin lymphoma can cause many symptoms, such as . -Swollen, painless lymph nodes in the neck, armpits or groin. -Unexplained weight loss . -Fever . -Soaking night sweats . -Coughing, trouble breathing or chest pain . -Weakness and tiredness that don't go away . -Pain, swelling or a feeling of fullness in the abdomen . Your doctor will diagnose lymphoma with a physical exam, blood tests, a chest x-ray, and a biopsy. Treatments include chemotherapy, radiation therapy, targeted therapy, biological therapy, or therapy to remove proteins from the blood. Targeted therapy uses substances that attack cancer cells without harming normal cells. Biologic therapy boosts your body's own ability to fight cancer. If you don't have symptoms, you may not need treatment right away. This is called watchful waiting. NIH: National Cancer Institute.  [from MedlinePlus]

Sezary syndrome

Sézary syndrome is an aggressive form of a type of blood cancer called cutaneous T-cell lymphoma. Cutaneous T-cell lymphomas occur when certain white blood cells, called T cells, become cancerous; these cancers characteristically affect the skin, causing different types of skin lesions. In Sézary syndrome, the cancerous T cells are called Sézary cells and are found in the skin, lymph nodes, and blood. A characteristic of Sézary cells is an abnormally shaped nucleus, described as cerebriform.People with Sézary syndrome develop a red, severely itchy rash (erythroderma) that covers large portions of their body. Sézary cells are found in the rash. However, the skin cells themselves are not cancerous; the skin problems result when Sézary cells move from the blood into the skin. People with Sézary syndrome also have enlarged lymph nodes (lymphadenopathy). Other common signs and symptoms of this condition include hair loss (alopecia), thickened skin on the palms of the hands and soles of the feet (palmoplantar keratoderma), abnormalities of the fingernails and toenails, and lower eyelids that turn outward (ectropion). Some people with Sézary syndrome are less able to control their body temperature than people without the condition.The cancerous T cells can spread to other organs in the body, including the lymph nodes, liver, spleen, and bone marrow. In addition, affected individuals have an increased risk of developing another lymphoma or other type of cancer.Sézary syndrome occurs in adults over age 60 and progresses rapidly; historically, affected individuals survived an average of 2 to 4 years after development of the condition, although survival has improved with newer treatments.Although Sézary syndrome is sometimes referred to as a variant of another cutaneous T-cell lymphoma called mycosis fungoides, these two cancers are generally considered separate conditions.

Mycosis fungoides

Mycosis fungoides is a malignant T-cell lymphoma of the skin, first reported (and named) by Alibert (1835). Sezary syndrome is a leukemic variant of mycosis fungoides defined by erythroderma with greater than 80% of the skin showing redness, adenopathy and greater than 1,000 circulating Sezary cells/microliter with a CD4+CD26- or CD4+CD7- phenotype. Sezary cells have a type 2 helper T cell cytokine profile. Sezary syndrome has a median overall survival time of only 2.4 years in patients with Sezary cells at a density of greater than 10,000 cells/microliter or 5.4 years in patients with 1,000-10,000 Sezary cells/microliter. Mycosis fungoides and Sezary syndrome are the most common cutaneous T-cell lymphomas. Sezary syndrome can arise de novo or can appear following years of chronic mycosis fungoides. Both are thought to arise from clonal expansion of CD4+ helper T cells responding to chronic antigen stimulation (summary by Wang et al., (2015)). [from OMIM]

Anaplastic large cell lymphoma

Anaplastic large cell lymphoma (ALCL) is a rare and aggressive peripheral T-cell non-Hodgkin lymphoma, belonging to the group of CD30-positive lymphoproliferative disorders, which affects lymph nodes and extranodal sites. It is comprised of two sub-types, based on the expression of a protein called anaplastic lymphoma kinase (ALK): ALK positive and ALK negative ALCL (see these terms). [from ORDO]

Lymphatic Diseases

The lymphatic system is a network of tissues and organs. It is made up of. -Lymph - a fluid that contains white blood cells that defend against germs. -Lymph vessels - vessels that carry lymph throughout your body. They are different from blood vessels. -Lymph nodes - glands found throughout the lymph vessels. Along with your spleen, these nodes are where white blood cells fight infection. Your bone marrow and thymus produce the cells in lymph. They are part of the system, too. The lymphatic system clears away infection and keeps your body fluids in balance. If it's not working properly, fluid builds in your tissues and causes swelling, called lymphedema. Other lymphatic system problems can include infections, blockage, and cancer.  [from MedlinePlus]
