All lymphnode swellings are due to lyphoma. Lymphnode enlargement may be due to infection in its draining area. Lipoma
is a lobulated structure consisting of fatty tissue and lymphnode is a firm structure and can be easily distinguished on ultrasound
There are less chances of lymphoma
and nothing to worry.
Consult your Surgeon and they will do histopathological examination and confirm the cause of enlarged lymphnode
