HPV-Associated Head and Neck Second Primary Tumors-A Case Series.

Background: There is limited understanding of head and neck second primary tumors (SPTs) in HPV-associated squamous cell carcinoma (SCC). Analogous to the concept of field cancerization of the upper airway known to contribute to the development of smoking-related head and neck SPTs, this case series reports four cases of HPV-associated SPTs.

Methods: We reviewed the charts of four patients diagnosed with HPV-associated oropharyngeal SCC who subsequently developed HPV-associated SPTs.
