Background: Papillomatosis is a known histopathologic pattern usually seen in human papillomavirus (HPV) infection and verruca vulgaris is the typical example. This pattern is also detected in some other benign cutaneous lesions such as nevus sebaceous (NS), seborrheic keratosis (SK), trichilemmoma (TL) and inverted follicular keratosis (IFK). The association between papillomatous lesions and HPV infection is questionable.
Objective: The objective of this study was to investigate the presence of HPV deoxyribonucleic acid (DNA) in non-genital benign papillomatous skin lesions (NS, SK, TL and IFK) by polymerase chain reaction (PCR).
Materials And Methods: A total of 100 specimens of non-genital NS, SK, TL and IFK were retrieved from archives of Dermatopathology Department of Razi Hospital, between 2003 and 2010. The conventional PCR using consensus GP5+/GP6+ primer and hydroxymethylbilane synthase gene as inner control was performed.
Results: PCR for HPV DNA revealed no positive results in any of 28 seborrheic keratosis (SK), 28 nevus sebaceous (NS), 28 inverted follicular keratosis (IFK) and 13 trichilemmoma (TL) studied specimens.
Conclusion: Papillomatosis is usually a characteristic pattern of HPV infection. However, we found no association between HPV infection and non-genital benign papillomatous lesions.

Background: Oral cancer is a common head and neck cancer malignancy that seriously affects patients' quality of life and increases the health care burden. Moreover, there is a lack of comprehensive reviews of previous research on factors associated with oral cancer. The aim of the current umbrella review was to provide a comprehensive and systematic summary of relevant studies, to grade the quality of evidence of relevant studies, and to provide guidance for the prevention of oral cancer.

Different types of feline papillomaviruses (PVs) are associated with a variety of skin lesions and neoplasia, such as papillomas and cell carcinomas, but the virus can also be found in healthy skin. In this review, the European Advisory Board on Cat Diseases (ABCD), a scientifically independent board of veterinary experts on feline infectious diseases from 11 European Countries, discusses the current knowledge of feline PV infections. Cats most likely become infected through lesions or abrasions of the skin.

This study explores the effects of plant compounds on human papillomavirus (HPV)-induced W12 cervical precancer cells and bioelectric signaling. The aim is to identify effective phytochemicals, both individually and in combination, that can prevent and treat HPV infection and HPV associated cervical cancer. Phytochemicals were tested using growth inhibition, combination, gene expression, RT PCR, and molecular docking assays.

Human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HPV-positive HNSCC) has distinct biological characteristics from HPV-negative HNSCC. Using an AI-based analytical platform on meta cohorts, we profiled expression patterns of viral transcripts and HPV viral genome integration, and classified the tumor microenvironment (TME). Unsupervised clustering analysis revealed five distinct and novel TME subtypes across patients (immune-enriched, highly immune and B-cell enriched, fibrotic, immune-desert, and immune-enriched luminal).

The papillomavirus E2 protein regulates the transcription, replication, and segregation of viral episomes within the host cell. A multitude of post-translational modifications have been identified which control E2 functions. A highly conserved di-lysine motif within the transactivation domain (TAD) has been shown to regulate the normal functions of the E2 proteins of BPV-1, SfPV1, HPV-16, and HPV-31.
