- The genetics, clinical features, and diagnosis of HLH are presented separately. (See Clinical features and diagnosis of hemophagocytic lymphohistiocytosis .). OVERVIEW AND INDICATIONS FOR TREATMENT. Hemophagocytic lymphohistiocytosis (HLH) is a progressive syndrome of unchecked immune activation and tissue damage. If left untreated, patients with HLH survive for only a few months, due to progressive multi-organ failure.

Alone we are rare. Together we are strong.â¥ Donate Today Non-Hodgkin lymphoma (also called non-Hodgkin's lymphoma, NHL, or just lymphoma) is cancer that starts in cells called lymphocytes, which are part of the body's immune system. Lymphocytes are in the lymph nodes and other lymphoid tissues (such as the spleen and bone marrow).Other types of cancer (lung or colon cancers, for example), can start in other organs and then spread to lymph nodes or other lymphoid tissue.ymphocytes are in the lymph nodes and other lymphoid tissues (such as the spleen and bone marrow).

Understanding Hodgkin Lymphoma -- the Basics Hodgkin lymphoma, also known as Hodgkin's disease, is a type of lymphoma, a cancer of the lymphatic system.The lymphatic system is a network of nodes (knots of tissue) connected by vessels that drain fluid and waste products from the body. The lymph nodes act as tiny filters, straining out foreign organisms and cells.odgkin lymphoma, also known as Hodgkin's disease, is a type of lymphoma, a cancer of the lymphatic system.

Hodgkin lymphoma (HL, formerly called Hodgkin's disease) is a neoplasm characterized by the presence of clonal malignant Hodgkin/Reed-Sternberg (HRS) cells (picture 1 and picture 2) in a reactive cellular background comprised of variable numbers of granulocytes, macrophages, plasma cells, and lymphocytes.

Marginal Zone Lymphoma Lymphoma is the most common blood cancer. The two main forms of lymphoma are Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL). Lymphoma occurs when cells of the immune system called lymphocytes, a type of white blood cell, grow and multiply uncontrollably. Cancerous lymphocytes can travel to many parts of the body, including the lymph nodes, spleen, bone marrow, blood, or other organs, and form a mass called a tumor.

Lymphoproliferative Disorders Clinical Presentation 1 Autoimmune lymphoproliferative syndrome (ALPS) : ALPS is characterized by lymphoproliferative disorder, autoimmune cytopenias, and a susceptibility to malignancy. 2  The pathogenesis involves defective FAS-induced apoptosis, which, in turn, leads to dysregulation of lymphocyte homeostasis.

Hemophagocytic Lymphohistiocytosis (HLH) is a life-threatening immunodeficiency. It affects people of all ages and ethnic groups. Common symptoms are fevers, enlarged spleen, low blood counts and liver abnormalities. At least half of the patients with HLH will also experience inflammation of the brain which can lead to a wide variety of neurologic problems.

Non-Hodgkin's and Hodgkin's Lymphoma Definition and Etiology. Non-Hodgkin's lymphoma (NHL) and Hodgkin's lymphoma (HL) are neoplasms arising from cells of the lymphoid lineage. T and B cells originate in the bone marrow, migrate to the thymus or peripheral lymphoid tissues respectively, and develop into highly specialized mediators of the adaptive immune response.

Haematopoiesis Diagram showing the development of different blood cells from haematopoietic stem cell to mature cells. Haematopoiesis (from Greek αἷμα, blood and ποιεῖν to make; also hematopoiesis in American English; sometimes also haemopoiesis or hemopoiesis) is the formation of blood cellular components.owever, maturation, activation, and some proliferation of lymphoid cells occurs in secondary lymphoid organs (spleen, thymus, and lymph nodes). In children, haematopoiesis occurs in the marrow of the long bones such as the femur and tibia.

Macrocytosis Macrocytosis is the enlargement of red blood cells with near-constant hemoglobin concentration, and is defined by a mean corpuscular volume (MCV) of greater than 100 femtolitres (the precise criterion varies between laboratories).astrointestinal diseases that may cause macrocytosis include celiac disease (severe sensitivity to gluten from wheat and other grains that causes intestinal damage) and Crohn’s disease (inflammatory bowel disease that can affect any part of the gastrointestinal tract).

What is Hodgkin lymphoma's effect on the lymphatic system? Hodgkin lymphoma, or HL, was formerly called Hodgkin's disease. It is a cancer of the lymphatic system, which is a part of the immune system that consists of a series of ducts or tubes that parallel the arteries and veins throughout the body. These lymph ducts drain a milky white fluid that contains byproducts of immune activity away from areas of inflammation and infection.
