Possible signs of childhood Hodgkin lymphoma include swollen lymph nodes, fever, night sweats, and weight loss.

These and other symptoms may be caused by childhood Hodgkin lymphoma or by other conditions. A doctor should be consulted if any of the following problems occur:

• Painless, swollen lymph nodes in the neck, chest, underarm, or groin.
• Fever.
• Night sweats.
• Weight loss for no known reason.
• Itchy skin.

Tests that examine the lymph system are used to detect (find) and diagnose childhood Hodgkin lymphoma.

The following tests and procedures may be used:

• Physical exam and history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient's health habits and past illnesses and treatments will also be taken.
• Lymph node biopsy: The removal of all or part of a lymph node. One of the following types of biopsies may be done:
  • Excisional biopsy: The removal of an entire lymph node.
  • Incisional biopsy: The removal of part of a lymph node.
  • Core biopsy: The removal of tissue from a lymph node using a wide needle.
  • Fine-needle aspiration (FNA) biopsy: The removal of tissue from a lymph node using a thin needle.

  A pathologist views the tissue under a microscope to look for cancer cells, especially Reed-Sternberg cells. Reed-Sternberg cells are common in classical Hodgkin lymphoma.

  
  
  Reed-Sternberg cell. Reed-Sternberg cells are large, abnormal lymphocytes that may contain more than one nucleus. These cells are found in Hodgkin lymphoma.
• Chest x-ray: An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body.
• CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
• Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following:
  • The number of red blood cells, white blood cells, and platelets.
  • The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.
  • The portion of the blood sample made up of red blood cells.
  
  
  Complete blood count (CBC). Blood is collected by inserting a needle into a vein and allowing the blood to flow into a tube. The blood sample is sent to the laboratory and the red blood cells, white blood cells, and platelets are counted. The CBC is used to test for, diagnose, and monitor many different conditions.
• Sedimentation rate: A procedure in which a sample of blood is drawn and checked for the rate at which the red blood cells settle to the bottom of the test tube.
• Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease in the organ or tissue that makes it.
• PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactiveglucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.
• Immunophenotyping: A test in which the cells in a sample of blood or bone marrow are looked at under a microscope to find out the type of malignant (cancerous) lymphocytes that are causing the lymphoma.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) and treatment options depend on the following:

• The stage of the cancer.
• The size of the tumor and how quickly it shrinks after initial treatment.
• The patient's symptoms when diagnosed.
• Certain features of the cancer cells.
• Whether the cancer is newly diagnosed, does not respond to initial treatment, or has recurred (come back).

The treatment options also depend on:

• The child's age and gender.
• The risk of long-term side effects.

Most children and adolescents with newly diagnosed Hodgkin lymphoma can be cured.
