Background
Oropharyngeal squamous cell carcinoma (OPSCC) arises in the middle pharynx, including the tonsils, base of the tongue, and surrounding tissues. While OPSCC commonly metastasizes to regional lymph nodes, distant metastases to sites like the liver are rare, occurring in about 1-4% of cases with advanced disease.
Case Presentation
A 66-year-old male presented to the emergency department with recurrent right-sided facial swelling and a two-week history of sore throat. CT imaging revealed a large right tonsillar mass extending to the base of the tongue. Further evaluation with PET scan showed hypermetabolic activity in the right tonsil, multiple hypermetabolic lymph nodes in the right neck (stations 1B, 2, 3, 4, 5), right supraclavicular fossa, and small retropharyngeal nodes. Additionally, PET scan detected a hypermetabolic lesion in the liver and focal activity at T10 suggestive of bone metastasis. Fine needle aspiration (FNA) confirmed squamous cell carcinoma. Biopsy of the liver lesion revealed metastatic squamous cell carcinoma with basaloid differentiation, positive for p40 and p63 stains. Clinical staging was T2b cN2 cM1. The patient’s case was discussed in tumor boards, leading to a treatment plan of palliative radiotherapy with radiosensitizer (weekly carboplatin/paclitaxel) due to recent myocardial infarction, precluding cisplatin or 5FU use. Post-radiotherapy, Pembrolizumab was planned based on 60% PD-L1 expression. The patient opted to forego additional systemic chemotherapy and currently receives Keytruda every three weeks.
Discussion
Liver metastases from head and neck SCC are rare, highlighting the complexity of treatment decisions in such cases. Effective management requires a multidisciplinary approach to optimize therapeutic outcomes while considering patient-specific factors and comorbidities.
Conclusions
This case underscores the challenges and poor prognosis associated with tonsillar SCC with liver metastases. It underscores the need for personalized treatment strategies tailored to the unique characteristics of each patient’s disease.
