Features of the medical history may point to the cause, such as the speed of onset of swelling, pain, and other constitutional symptoms such as fevers or weight loss. [33] For example, a tumour of the breast may result in swelling of the lymph nodes under the arms [29] and weight loss and night sweats may suggest a malignancy such as lymphoma. [29]

The retropharyngeal lymph nodes, from one to three in number, lie in the buccopharyngeal fascia, behind the upper part of the pharynx and in front of the arch of the atlas, being separated, however, from the latter by the longus capitis. Their afferents drain the nasal cavities, the nasal part of the pharynx, and the auditory tubes.
The most common cause of enlargement of the submental lymph nodes are infections (including viral infections (mononucleosis, Epstein-Barr virus infection, and cytomegaloviral infections), toxoplasmosis, and dental infections (e.g. periodontitis)). [1] The lymph nodes may be affected by metastatic spread from cancers of their drained territories ...
