Which HPV strains are associated with squamous papilloma?

Human Papillomavirus (HPV) has various strains, some of which are linked to different conditions affecting the skin and mucous membranes. Squamous papillomas are benign epithelial tumors that typically present as small, wart-like growths.

HPV strains 6 and 11 are specifically associated with squamous papilloma. These strains are considered low-risk for malignancy, and they are more commonly linked to benign lesions, such as squamous papillomas in different areas of the body, including the oral cavity and genital regions. Their role in benign epithelial growths is well documented, which strongly supports the association between these HPV strains and squamous papilloma.

On the contrary, other strains mentioned in the question have different associations. For instance, strains like HPV 16 and 18 are high-risk types associated with the development of cervical and other forms of cancer, rather than benign lesions like squamous papilloma. Understanding the specific strains of HPV and their associations with various lesions is crucial for diagnosing and managing HPV-related conditions effectively.
