Background: Seborrheic keratoses (SK) are the most common acquired benign tumor that affects middle-aged or older adults with great cosmetic concern. Clinical and histopathological similarities of SK and common warts have been addressed by investigating the possible presence of human papillomavirus (HPV) DNA in SK. Previous studies suggested the association between α-genus HPV and SK located on genital skin, whereas the causal relationship between α-HPV and non-genital SK remains controversial.
Aim: This study aimed to clarify the pathogenic involvement of α-HPV in the development of non-genital SK.
Methods: We analyzed α-HPV DNA prevalence and HPV genotypes using a PCR-based microarray on 51 skin samples presenting with histologically confirmed SK without any malignant changes. Correlation between the histological subtype of SK and their HPV DNA-positive reactivity was also evaluated.
Results: Of 51 non-genital SK, two (3.9%) skin samples were positive for α-HPV DNA; high-risk HPV 31 and low-risk HPV 42 were found. Evaluation of HPV prevalence in different histological types of SK showed that both HPV-positive cases were acanthotic type; 14.3% of acanthotic SK lesions were positive, while all of the other types were negative for α-HPV.
Conclusions: This study demonstrates that α-HPV positivity is very rare in common non-genital SK. The rare α-HPV-positive SK lesions histologically belonged to the acanthotic type, implying a potential impact of HPV infection on epidermal hyperproliferation. Although a possible association cannot be excluded, our findings suggest that α-HPV is not a major causative factor for non-genital SK.

The E6 and E7 proteins of the high risk human papillomaviruses (HR HPVs) play a key role in the oncogenesis associated with papillomavirus infection. Data on the variability of these proteins are limited, and the factors affecting their variability are still poorly understood. We analyzed the variability of the currently known sequences of the HPV type 16 (HPV16) E6 and E7 proteins, taking into account their geographic origin and year of sample collection, as well as the direction of their evolution in the major geographic regions of the world.

This editorial initiative gave us the opportunity to reflect on the relations between accuracy measures, prevalence and characteristics of the tested population in the case of HPV-based screening. In screening test evaluation, we look at the clinical accuracy of the test as an intrinsic characteristic of the assay, which interacts with the characteristics of the population, the result being the screening performance.

Cervical cancer is primarily driven by persistent infection with high-risk human papillomavirus (HPV) strains and remains a significant global health challenge, particularly in low- and middle-income countries where late-stage diagnoses is common. While vaccination and screening programs have reduced incidence rates, the need for novel and more effacacious and cost-effective therapeutic options is therefore critical especially for advanced cervical cancer. This review highlights several key advances in the understanding of HPV-induced carcinogenesis and the development of therapeutic strategies over the past five years.

Background: Gay, bisexual, and other men who have sex with men (gbMSM) have a higher risk of human papillomavirus (HPV) infection and related diseases and would benefit from preventive measures such as HPV vaccination. We assessed the association between HPV vaccination and anal HPV infection in HIV-negative gbMSM and gbMSM living with HIV from the Lubricant Investigation in Men to Inhibit Transmission of HPV Infection study.
Methods: Participants attended 7 visits over 12 months where they provided a nurse-collected anal sample and self-completed a questionnaire on risk factors and HPV vaccination.
