🩺 Practical Clinical Tip

Size alone is not diagnostic.

Eccentric cortical thickening and loss of fatty hilum are more concerning than symmetric mild thickening.

🌍 English Summary

Normal axillary lymph nodes usually have cortical thickness less than 3 mm with preserved fatty hilum.

Cortical thickness above 4–5 mm, especially with eccentric thickening and hilum loss, increases suspicion and may require biopsy.

Morphology is more important than size alone.
