Evaluation of the neck mass.

The differential diagnosis of a neck mass is extensive and varies with the age of the patient at presentation. A thorough work-up including an accurate history and complete head and neck examination often narrows the diagnostic possibilities. The fine needle aspiration biopsy has become an invaluable tool to aid clinicians in the evaluation of the neck mass and is safe, accurate, and cost-effective with minimal complications. The possibility of malignancy in any age group, especially in the late adult group, should never be overlooked. Close follow-up and aggressive pursuit of a diagnosis with appropriate work-up facilitates a timely and accurate treatment plan, which is essential to a favorable outcome.
