Axillary lymphadenopathy refers to the swelling or enlargement of lymph nodes in the armpit (axilla). These lymph nodes are an important part of the immune system, filtering lymph fluid and trapping bacteria, viruses, and other harmful substances. Swollen axillary nodes can occur due to infections, autoimmune conditions, or cancers.

Early evaluation is crucial, as it helps identify whether the cause is benign or requires specialized treatment. Dr. Ritika Bhandari provides comprehensive assessment and management for axillary lymphadenopathy, ensuring accurate diagnosis and effective care.

Causes of Axillary Lymphadenopathy

The swelling of axillary lymph nodes can arise from several factors:

1. Infections

• Bacterial Infections: Conditions like tuberculosis, staphylococcal or streptococcal infections, and cat-scratch disease can cause localized node enlargement.

• Viral Infections: Viruses such as Epstein-Barr virus (EBV), cytomegalovirus (CMV), or HIV can lead to generalized lymph node swelling, including the axilla.

• Fungal and Parasitic Infections: Rare causes, often seen in immunocompromised patients, include fungal infections like histoplasmosis or parasitic infestations.

2. Inflammatory Conditions

• Autoimmune Disorders: Diseases like rheumatoid arthritis or systemic lupus erythematosus can trigger node enlargement.

• Reactive Lymphadenopathy: Temporary node swelling may occur in response to infection or inflammation in nearby tissues.

3. Neoplastic Conditions

• Primary Lymphomas: Both Hodgkin and non-Hodgkin lymphomas can present with axillary lymph node enlargement.

• Metastatic Cancer: Cancers from the breast, melanoma, or lung may spread to axillary nodes.

• Leukemia: Certain leukemias, particularly chronic lymphocytic leukemia, can lead to lymph node swelling.

4. Medications and Vaccinations

Some medications (e.g., phenytoin) and recent vaccinations (like COVID-19 vaccines) can temporarily enlarge lymph nodes.

Symptoms of Axillary Lymphadenopathy

The primary symptom is swelling or a lump in the armpit. Additional symptoms vary depending on the underlying cause:

• Pain or Tenderness: Nodes due to infection or inflammation are often tender; cancerous nodes are usually firm and painless.

• Redness or Warmth: Indicates infection.

• Fever, Chills, and Fatigue: Common in systemic infections or inflammatory conditions.

• Weight Loss and Night Sweats: Concerning signs that may suggest malignancy or chronic infection.

• Reduced Arm Mobility: Large nodes may cause discomfort or restrict shoulder and arm movement.

Diagnosis of Axillary Lymphadenopathy

Dr. Ritika Bhandari follows a systematic approach for accurate diagnosis:

1. Clinical Examination: Detailed history and physical assessment of the nodes.

2. Blood Tests: Evaluate infection, inflammation, or hematologic disorders.

3. Imaging Studies: Ultrasound, mammography, or CT scans help identify underlying causes.

4. Biopsy: Fine-needle aspiration or excisional biopsy may be performed if malignancy or persistent swelling is suspected.

Treatment Options

Treatment depends entirely on the cause:

• Infections: Antibiotics or antiviral medications as needed.

• Autoimmune Conditions: Immunosuppressive therapy or disease-specific medications.

• Cancer: Oncologic treatment including surgery, chemotherapy, or radiation, guided by tumor type and stage.

• Supportive Care: Pain management and monitoring of node changes.

When to Consult Dr. Ritika Bhandari

Immediate consultation is recommended if you notice:

• Persistent or rapidly enlarging lump in the armpit

• Firm, painless nodes

• Fever, night sweats, or unexplained weight loss

• Redness, warmth, or tenderness over the swollen nodes

With advanced diagnostics and personalized treatment plans, Dr. Ritika Bhandari ensures accurate evaluation and effective management of axillary lymphadenopathy, helping patients achieve the best possible outcomes.
