- Overview:
- Nasopharyngeal carcinoma (NPC):
- Typically presents with a painless upper-neck mass plus nasal, aural, and cranial nerve symptoms:
- Reflecting the tumor’s origin in the fossa of Rosenmüller with lateral (parapharyngeal) and superior (skull base) spread
- Typically presents with a painless upper-neck mass plus nasal, aural, and cranial nerve symptoms:
- Early symptoms are non-specific:
- So most patients present at advanced stage (III to IV)
- Nasopharyngeal carcinoma (NPC):
- Presenting features by mechanism:
- Neck mass (regional nodal spread):
- Most common presentation (~75%):
- Painless enlarged upper cervical node:
- Often the first / only sign
- Painless enlarged upper cervical node:
- Retropharyngeal and level II nodes:
- Are first echelons
- May occur without a visible primary
- Most common presentation (~75%):
- Nasal symptoms (primary tumor):
- Epistaxis or blood-tinged discharge
- Unilateral nasal obstruction
- Rhinorrhea (nasal dysfunction ~73%)
- “Nasal twang” or voice change with large tumors
- Aural / eustachian tube dysfunction:
- Unilateral serous otitis media
- Conductive hearing loss
- Tinnitus
- Aural fullness (~62%):
- The feeling of pressure, clogging, or fullness inside the ear:
- Often described as having water or air trapped inside
- The feeling of pressure, clogging, or fullness inside the ear:
- Skull-base / cranial nerve involvement:
- Headache (~35%)
- Facial pain / numbness (CN V)
- Diplopia (~11%, CN VI)
- Cranial nerve palsy in ~20% of the cases at diagnosis
- Most affected nerves:
- CN V and VI, plus III and XII
- Advanced disease may cause cavernous sinus syndrome and multiple cranial neuropathies
- Less common findings:
- Trismus (~3%, pterygoid muscle invasion)
- Nasal regurgitation (soft-palate paresis)
- Symptoms of distant metastasis:
- Bone, lung, liver
- Anorexia / weight loss uncommon:
- If present, raise suspicion for distant spread
- Neck mass (regional nodal spread):
- Evaluation:
- Complete head and neck exam with nasopharyngeal fiberoptic endoscopy; neck palpation
- EBV testing:
- Endemic undifferentiated / nonkeratinizing subtypes strongly EBV-associated
- Biopsy of nasopharyngeal lesion
- MRI skull base to clavicle
