Intraparotid nodal metastases refer to metastatic involvement of intraparotid lymph nodes from either a primary parotid tumor or an extraparotid tumor in the head and neck (e.g. nasopharyngeal carcinoma).
Pathology
Location
There may be a predilection towards the superficial lobe or tail region of the parotid 3.
Treatment and prognosis
- the presence of intraparotid metastatic nodal involvement in those with a known head and neck skin squamous cell carcinoma might imply occult cervical nodal involvement 2
- the presence of intraparotid metastatic nodal involvement in those with a known primary parotid cancer can be strongly associated with a worse disease-specific survival and a higher risk of locoregional recurrence 4
