Management of Painful Axillary Lymph Node in Men

Initial Diagnostic Approach

• The American College of Radiology recommends axillary ultrasound to characterize lymph node morphology, looking specifically for cortical thickness and uniformity 1
• The evaluation should include assessment of size and shape (round vs. oval) of the lymph node 2
• Vascularity pattern should be evaluated as part of the ultrasound assessment 2, 3

Tissue Diagnosis

• The National Comprehensive Cancer Network recommends ultrasound-guided fine needle aspiration (FNA) or core biopsy to establish a definitive diagnosis if ultrasound reveals suspicious features 2, 4

Follow-Up Protocol for Benign Results

• The American College of Radiology recommends ultrasound monitoring every 6 months for 1-2 years to ensure stability and detect any changes in size, morphology, or cortical features 1
• Re-biopsy should be considered if there are changes in lymph node characteristics during follow-up 1

Additional Imaging Considerations

• The American College of Radiology recommends considering PET/CT if there is concern for lymphoma or other non-breast malignancy 1
• CT chest/abdomen/pelvis may be warranted to evaluate for primary malignancy if metastatic disease is suspected 3
