Hpv and skin cancer
Squamous cell carcinoma and hpv
The risk of cutaneous squamous cell carcinoma (SCC) is higher in immunocompromised patients and is linked to the beta human papillomavirus (-HPV). Strickley, Messerschmidt, and colleagues have now shown that -HPV infection is not causal in the production of SCC in the sense of immunosuppression, but that the loss of -HPV-mediated T cell immunity is.
The importance of commensal HPVs in priming adaptive immunity in immunocompetent hosts is highlighted in this research, which opens the door to developing antiviral T cell-based vaccines to prevent skin cancer.

Certain forms of cutaneous human papillomaviruses (HPVs) are still debated in the scientific community as to whether they are causally involved in the growth of non-melanoma skin cancer (NMSC). In addition to tissue culture systems, deciphering the etiological function of cutaneous HPVs necessitates adequate preclinical models to align the obtained findings with clinical data from affected patients. To provide rational reasons for public health organizations to identify at least some cutaneous HPVs as group 1 carcinogens, clear scientific evidence about the etiology and underlying mechanisms involved in NMSC production is essential. This, in turn, will have ramifications for fundraising organizations and health-care decision-makers, forcing the introduction of a broad vaccination campaign against “high-risk” cutaneous HPVs, similar to those used to prevent anogenital cancer, in order to prevent NMSC from being the most common cancer on the planet. Understanding the functional and clinical effect of cofactors that influence the individual outcome and tailored treatment of a disease requires a precise understanding of the multi-step progression from normal cells to cancer. This review reflects aspects of causality in medicine, the use of empirically meaningful model systems, and preventive strategies, as well as recent arguments in favor of accepting a viral etiology in NMSC growth.

Scientists and doctors have been investigating and researching the detection of lesions in areas of the body where UV radiation from the sun is less likely to cause cancer in recent years. This perceived association between viruses and skin cancer has been the subject of much debate in the medical community.
This suggests that UV exposure isn’t to blame for any case of skin cancer, and that the disease can be affected by other causes as well. In addition, there is an increasing body of evidence linking human papillomavirus (HPV) to skin squamous cell carcinoma (SCC) and cutaneous squamous cell carcinoma (CSCC) (cSCC).
In the midst of a global pandemic, the word “virus” has a negative connotation. Historically, we associated the word “virus” with transient illnesses such as the common cold or one-day flu, all of which have easy cures. Some viruses, on the other hand, can cause cancer. According to a new report, the hepatitis B virus causes over 350,000 cases of liver cancer per year around the world. These figures can be mind-boggling and terrifying.
High-risk HPV has an oncogenic function in anogenital, head and neck, and cervical cancers, but not in skin cancer in the general population. Some authors have shown that they appear primarily on the hands and feet, particularly in the area of the nail bed, which could be due to HPV types from anogenital regions contaminating the area. We present a case of genital HPV in an immunocompetent young man with SCC on the nose tip, which was verified by histopathological findings and in situ hybridization. The significance of this study is to draw attention to HPV’s possible function in the etiology of skin cancer in immunocompetent people.
Our understanding of the natural history of human papillomavirus (HPV) infection and its function in the development of cervical and other anogenital cancers has advanced dramatically over the last decade. While HPV’s function in skin carcinogenesis has been well known in immunocompromised individuals, its relationship with cutaneous cancers in immunocompetent individuals is still a hot topic of discussion. 1–4
