Proton Therapy Case Study: HPV-related Squamous Cell Carcinoma of the Tonsil
Proton Therapy Case Study: HPV-related Squamous Cell Carcinoma of the Tonsil Presentation and Examination In May 2020, a 50-year-old healthy, nonsmoking man presented with a painless mass in the left neck and odynophagia for the preceding month. Diagnosis A contrast-enhanced CT scan of the neck revealed 3.2 cm and 1 cm cervical level II lymph nodes, with no obvious primary tumor. Subsequent fine-needle aspiration biopsy was performed on the left level II lymph node, which revealed a p16 (HPV) positive squamous cell carcinoma (SCC).
