In adults, the solitary lateral cystic neck mass remains a diagnostic challenge with little solid material to target for cytology and few clues on imaging modalities to suggest underlying malignancy.
This study was a retrospective review of patients presenting with a lateral cystic neck mass to a tertiary academic head and neck centre over a 10-year period.
A total of 25 of 157 cystic lesions were subsequently malignant on paraffin section histopathology, with the youngest patient being 42 years. In the age cohort over 40 years, 30 per cent of males and 10 per cent of females were diagnosed with malignancy. The ipsilateral palatine tonsil was the most common primary site (50 per cent). A total of 85 per cent of cases demonstrated integrated human papillomavirus infection. Age, male sex and alcohol were significant risk factors on univariate analysis. Ultrasound-guided fine needle aspiration cytology and magnetic resonance imaging represented the most accurate pre-open biopsy tests.
The authors of this study advocate for a risk-stratified, evidence-based workup in patients with solitary lateral cystic neck mass in order to optimise timely diagnosis.
