R59.1

Clinical Causes: Infections such as common colds, influenza, mononucleosis, or bacterial infections Chronic inflammatory diseases like rheumatoid arthritis or lupus The uptake of certain medications causing drug reactions Cancers such as lymphoma, leukemia, or metastatic cancers from other organs Other immune system disorders or systemic illnesses

Key Symptoms: Swollen, enlarged lymph nodes palpable under the skin, often tender or painful Fever and night sweats Unexplained weight loss Fatigue or weakness Additional signs depending on underlying cause, such as sore throat, cough, or skin rashes

Diagnosis Path: The diagnosis of generalized lymphadenopathy involves a thorough medical history review, physical examination, and various diagnostic tests. Blood tests can identify infections or immune disorders. Imaging studies like ultrasound, CT scans, or MRI help visualize the lymph nodes' size and distribution. In some cases, a biopsy of a lymph node may be necessary to determine if malignancy or specific infections are involved.

Treatment Protocols: Treatment of enlarged lymph nodes depends on the underlying cause. If an infection is responsible, antibiotics or antiviral medications may be prescribed. Autoimmune conditions might require corticosteroids or immunosuppressants. When cancer is diagnosed, treatment options include chemotherapy, radiation therapy, or surgical removal of the affected lymph nodes. Supportive care, such as pain relievers and rest, can help manage symptoms while addressing the primary cause.
