C83.9
Non-follicular (diffuse) lymphoma, unspecified
Clinical Classification Guidelines
Medical Intelligence & Overview
Non-follicular (diffuse) lymphoma, classified under ICD-10 code C83.9, is a type of lymphatic system cancer that originates from lymphocytes, a kind of white blood cell. Unlike follicular lymphomas, which tend to grow slowly and in a structured pattern, non-follicular lymphomas are characterized by their diffuse, less organized spread within lymph nodes. This form of lymphoma can develop in various parts of the lymphatic system and sometimes spreads to other organs. Understanding this condition involves grasping its causes, symptoms, how it is diagnosed, and available treatments.
Causes & Symptoms
Clinical Causes: Genetic mutations within lymphocytes that lead to uncontrolled growth Inherited genetic factors that may predispose individuals to lymphoma Exposure to certain chemicals like pesticides and herbicides History of infections such as Epstein-Barr virus (EBV), HIV, or Helicobacter pylori Weakened immune system due to autoimmune diseases or immunosuppressive treatments
Key Symptoms: Swollen lymph nodes, typically painless, in neck, armpits, or groin Unexplained weight loss Persistent fever not caused by infection Night sweats Fatigue or weakness Unintentional weight loss Shortness of breath or coughing if the lymphoma affects the chest area Abdominal pain or swelling when organs are involved
Diagnostic & Treatment
Diagnosis Path: Physical examinations to check for swollen lymph nodes or other abnormalities Blood tests to evaluate overall health and detect signs of lymphoma Imaging studies such as CT scans, PET scans, or MRI to locate affected areas Biopsy of the lymph node or involved tissue to examine the cells microscopically Immunohistochemistry and molecular studies to identify specific markers that confirm lymphoma subtype
Treatment Protocols: Chemotherapy to kill cancerous cells and control disease progression Immunotherapy, including monoclonal antibodies like rituximab, to target lymphoma cells specifically Radiation therapy for localized disease areas Targeted therapies that interfere with specific molecules involved in lymphoma growth Stem cell or bone marrow transplants in more advanced cases or relapsed disease Supportive care to manage symptoms and improve quality of life
