C82.92

Clinical Causes: Genetic mutations within lymphocytes that lead to abnormal cell growth Age-related changes, mostly affecting older adults over 60 years Possible environmental exposures, such as certain chemicals or radiation, though specific causes are often unknown Family history of lymphatic or hematologic cancers Weakened immune system, either from autoimmune diseases or immunosuppressive treatments

Key Symptoms: Swollen lymph nodes, often painless, in the chest area or other regions Persistent cough or chest discomfort due to enlarged lymph nodes pressing on airways Unexplained weight loss and fatigue Fever and night sweats without apparent infection Shortness of breath or chest tightness, especially if the intrathoracic nodes are significantly enlarged General weakness and feeling of malaise

Diagnosis Path: Imaging studies such as chest X-rays and CT scans to identify enlarged lymph nodes within the chest cavity Biopsy procedures, where a tissue sample from a swollen lymph node is examined microscopically to confirm lymphoma Laboratory tests, including blood tests to assess overall health and detect abnormal cells Bone marrow examination, if necessary, to determine if the disease has spread to the marrow Immunophenotyping and molecular testing to classify the lymphoma subtype and guide treatment decisions

Treatment Protocols: Watchful waiting or active surveillance for asymptomatic cases or slow progression Chemotherapy, often combined with immunotherapy agents such as monoclonal antibodies (e.g., rituximab) Radiation therapy, particularly for localized disease or symptomatic lymph nodes Targeted therapies that focus on specific molecules involved in lymphoma growth Stem cell transplantation in advanced cases or relapsed disease Supportive care to manage symptoms and improve quality of life, including medications for pain, infections, or other complications
