Diagnosis and Management of Neck Masses

Clinical Evaluation

The American Academy of Otolaryngology-Head and Neck Surgery recommends a thorough head and neck examination to assess for neck masses, including inspection and palpation of the oral cavity, oropharynx, and neck, in patients presenting with a neck mass 1, 3, 2
The American Academy of Otolaryngology-Head and Neck Surgery suggests that any neck mass present for several days to weeks without infectious etiology must be considered malignant until proven otherwise 1, 3
The American College of Radiology recommends contrast-enhanced CT neck (or MRI) as the initial imaging modality for a palpable neck mass in an adult, particularly given cancer risk 6, 1

The American Academy of Otolaryngology-Head and Neck Surgery states that a mass present for more than 2 weeks without infectious etiology, difficulty swallowing, and location in the anterior neck are concerning features for malignancy 1, 3, 2
The American Academy of Otolaryngology-Head and Neck Surgery recommends assessing for red flags such as tobacco or alcohol use, weight loss, fever, night sweats, and prior head/neck malignancy or radiation 1, 3, 2

The American Academy of Otolaryngology-Head and Neck Surgery recommends fine needle aspiration (FNA) as the first-line tissue sampling technique for neck masses at increased risk for malignancy 1, 8, 9
The American College of Radiology suggests that ultrasound may be appropriate for discrete cystic lesions or thyroid nodule characterization, and can guide fine needle aspiration 6, 4, 7

The American Academy of Otolaryngology-Head and Neck Surgery recommends urgent referral to head and neck surgery/ENT within 1 week for non-thyroid masses with malignancy features 1, 3
The American Academy of Otolaryngology-Head and Neck Surgery suggests that empiric antibiotics should not be used unless there is a clear infectious etiology, as this can delay cancer diagnosis 1, 3
