Human papillomavirus-associated head and neck squamous cell carcinoma, abbreviated HPV-associated SCC and HPV-NHSCC, is a type of head and neck squamous cell carcinoma.

It has a unique epidemiology, when compared to conventional head and neck squamous cell carcinoma.

General

  • Tumours associated with high risk HPV, typically HPV 16.[1]
    • Thought to be different that tumours driven by alcohol and tobacco use.[2]
      • Patients tend to be male and slightly younger - risk thought to be due to sexual practices.[3]
  • Lesions more radiosensitive and usually have a better prognosis.[1]

Gross

Classic locations:

  • Tonsil and base of tongue[4] (palatine tonsil, lingual tonsil, oropharynx).

Note:

  • Memory device:
    • Where the tip of the penis goes when someone is deep throating.

Microscopic

Features:[5]

  • Typically non-keratinizing squamous cell carcinoma.
