C83.398
Diffuse large B-cell lymphoma of other extranodal and solid organ sites
Clinical Classification Guidelines
Medical Intelligence & Overview
Diffuse large B-cell lymphoma (DLBCL) is a type of non-Hodgkin lymphoma characterized by the rapid growth of large B lymphocytes in various parts of the body. When this lymphoma occurs outside the lymph nodes, affecting solid organs and other extranodal sites, it is classified under the code C83.398. Recognized as an aggressive and potentially curable form of lymphoma, DLBCL requires timely diagnosis and treatment to improve outcomes.
Causes & Symptoms
Clinical Causes: Genetic mutations that lead to uncontrolled B-cell growth Exposure to certain chemicals or pesticides Previous history of other lymphoid malignancies Infections such as HIV or Epstein-Barr virus can increase risk Age, with higher incidence in older adults Immunosuppressive therapy or conditions that weaken the immune system
Key Symptoms: Swelling or a noticeable lump in affected areas, including the abdomen, chest, or skin Unexplained weight loss Persistent fatigue or weakness Fever that does not resolve Night sweats Pain or discomfort in areas of tumor growth Other symptoms depending on the affected organ, such as breathing difficulty if lungs are involved
Diagnostic & Treatment
Diagnosis Path: Physical examination to palpate enlarged lymph nodes or palpable masses Imaging studies like CT scans, PET scans, or MRI to identify affected organs and the extent of disease Biopsy of affected tissue to confirm lymphoma type and subtype Blood tests to assess overall health and organ function Additional tests may include bone marrow biopsy or cerebrospinal fluid analysis if necessary
Treatment Protocols: Chemotherapy with regimens such as R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) Targeted therapies like monoclonal antibodies (e.g., rituximab) Radiation therapy, particularly if localized disease is present Stem cell transplant in cases of relapse or refractory disease Supportive care to manage side effects and maintain overall health during treatment
