p16 is a commonly used immunostain. It can be considered a surrogate marker for HPV infection. p16, like most other "p" stains, is a nuclear stain.
Pattern
- Nuclear stain +/- cytoplasmic staining.
Use
- Squamous lesions of the uterine cervix - see HSIL.
- Head and neck squamous cell carcinoma, specifically human papillomavirus-associated head and neck squamous cell carcinoma.
Tumours
Positive
- Squamous cell carcinoma - esp. cervical SCC, anal SCC, penile SCC, HPV-associated head and neck SCC.
- High grade urothelial carcinoma ~86% of cases.[1]
Negative
- Breast carcinoma.
- Prostate carcinoma.
- Lung squamous cell carcinoma.[1]
