What is happening?

Draining a cyst. In this location and in a young adult patient I suspect a branchial cleft cyst but would make sense to send for cytology and microbiology

FNA. Fine needle aspiration. That doesn’t look good at macro glance.

Cisti colloidea

It appears to be draining a cyst.

Lymph node aspiration: pus is draining rule out TB

Fairly dangerous place Fairly thick needle Serous Watery slightly blood tinged discharge indicates likely a ranula It's always better to do it under Ultrasonic guidance to prevent untoward injury to other structures in vicinity

Lymph node abscess drainage

Sialocele? Why 18g. Thats brutal.

Aspiration of cyst.

FNA

Aspiration..

Branchial cyst, there are many kinds like congenital, infectious and neoplastic. Fine needle aspiration done to identify infection and or the type of cells.
