Neck masses commonly arise from lymph nodes or salivary glands. Depending on the anatomical position it can be difficult to differentiate between the two.

 

 

Benign infective cervical lymphadenopathy is the most common cause of neck masses. They are usually tender, and resolve within 2-3weeks. Persistent neck masses should be thoroughly investigated to exclude neoplasms.

 

 

Any neck masses that persist beyond 3 weeks should be investigated to exclude neoplastic causes, especially in high risk patients, or where the cause is not apparent. A thorough physical examination of the sinonasal cavities, upper  areodigestive tract, and head and neck regions must be performed if secondary cervical metastases is suspected. Imaging with ultrasound or CT, with a fine needle aspiration biopsy (FNAB) should be performed.

 

 

Generally if the FNAB is non-diagnostic, or if there is any doubt of the diagnosis, and excisional biopsy may be required for diagnostic purposes. Masses arising from salivary glands are most likely to be benign pleomorphic adenomas, although these can undergo malignant transformation. The most common malignant lesion in the parotid gland in Australia is metastic squamous cell carcinoma. Unless there are medical contraindications, complete and full excision of salivary gland masses is recommended.
