produced an influential classification in 1938. However, this system was based upon anatomical landmarks found in dissection, making it imperfectly suited to the needs of clinicians, which led to new terminology for the lymph nodes that could be palpated.
More recently, classification systems have been proposed organized around what can be observed via diagnostic imaging.
Commonly used systems have been devised by the American Academy of Otolaryngology
and the American Joint Committee on Cancer
