What causes the preauricular to swell?
The lymph nodes in front of the ear are called the preauricular lymph nodes.

They may also swell if you have the flu or mononucleosis.
What does it mean when your preauricular lymph node is swollen?

Lymphoma is cancer that originates in the cells of the lymphatic system. The most common types are Hodgkin lymphoma and non-Hodgkin lymphoma.
