NHL causes the cells in the lymphatic system to abnormally reproduce, eventually causing tumors to grow. Lymphomas (including both Hodgkin and non-Hodgkin lymphomas) are the third most common childhood cancer in the U.S.
NHL affects males more often than females, and is more common among white children than among African-American children and children of other races.
Staging and classification of non-Hodgkin lymphoma is based on the extent of the disease and the specific cells involved.
There has been much investigation into the association of the Epstein-Barr virus that causes the mononucleosis infection, as well as HIV, which causes AIDS. Children and adults with certain hereditary immune system abnormalities have an increased risk of developing non-Hodgkin lymphoma, including patients with ataxia telangiectasia, X-linked lymphoproliferative disease, or Wiskott-Aldrich syndrome. In many cases, non-Hodgkin lymphoma in children may not cause symptoms until it has grown or spread. Most children have stage III or IV disease at the time of diagnosis because of the sudden onset of symptoms and the fact that these lymphomas tend to grow very quickly. Some children with non-Hodgkin lymphoma have symptoms of an abdominal mass and have complaints of abdominal pain, fever, constipation, and decreased appetite due to the pressure and obstruction a large tumor in this area can cause. The symptoms of non-Hodgkin lymphoma may resemble other blood disorders or medical problems. On the facade of the house, a round plaque placed by the Westminster City Council and by Mr. An ear, nose and throat specialist (ENT) is a physician trained in the medical and surgical treatment of the ears, nose, throat, and related structures of the head and neck (Fig. ENTs have special expertise in managing diseases of the ears, nose and nasal passage sinuses, larynx (voice box), oral cavity and upper pharynx (mouth and throat), as well as structures of the neck and face (Fig. The lymphatic system is part of the immune system and functions to fight disease and infections.
Bean-sized organs, found in the underarm, groin, neck, chest, abdomen, and other parts of the body, that act as filters for the lymph fluid as it circulates through the body.

Lymphoblastic non-Hodgkin lymphoma accounts for about 30 percent of the cases, usually involves the T-cells (T-lymphocytes), and typically presents with a mass in the chest, swollen lymph node(s), with or without bone marrow and central nervous system involvement. Burkitt's and non-Burkitt's lymphoma are fast-growing lymphomas in which the cells are undifferentiated and diffuse. Large cell or diffuse histiocytic non-Hodgkin involves the B-cells or T-cells and accounts for about 25 percent of the cases.
The lymphoma is in the chest or spine, or it has spread widely in the abdomen, or it is both above and below the diaphragm, but it does not involve bone marrow or the central nervous system. It is possible that genetics and exposure to viral infections may increase the risk for developing this malignancy. Both of these infectious viruses have been linked to the development of Burkitt's lymphoma. Lymphomas in the chest can also press on a main blood vessel (the superior vena cava), which can cause swelling and a bluish coloration in the head and arms. The use of invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film. A diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce images (often called slices) of the body. A diagnostic imaging technique that uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs.

Children with this type of non-Hodgkin lymphoma usually have lymphatic system involvement, as well as a nonlymph structure (such as lung, jaw, skin, and bone) involvement.
A child can go from otherwise healthy to having multisystem involvement in a short time period.

A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs.
Tissues that use the glucose more than normal tissues (such as tumors) can be detected by a scanning machine.
The energy from the radio waves creates patterns formed by different types of tissue and diseases. The well trained ENT specialist has a thorough knowledge of all of the organs and physical structures in the head and neck region. The images from a PET scan are not finely detailed like a CT or a MRI scan, but they can show areas of increased cellular activity anywhere in the body, even if they don't show up on other tests. PET scans can be used to find small tumors or to check if treatment for a known tumor is working. It was renamed the Metropolitan Ear Nose and Throat Hospital - the first hospital of its kind in the world. Ear nose and throat specialists are trained to handle surgeries where organs need to be removed; these may include the adenoids (Fig.
They are usually characterized by a large abdominal tumor and may have bone marrow and central nervous system involvement. Side effects of radiation and chemotherapy, as well as second malignancies, can occur in survivors of non-Hodgkin lymphoma. New methods are continually being discovered to improve treatment and to decrease side effects. Yearsley, the first surgeon to specialise in these disorders, did much to improve the status of aural surgery, demonstrating how the ear had an influence on the nose and throat"1.
