Human papillomavirus (HPV) infection has been demonstrated in some of the nonmelanoma skin cancers as well as in precancerous lesions. Multiple infections of mucosal high-risk HPV may contribute to the onset of digital Bowen's disease through, if any, digital-genital transmission. We screened for the presence of the mucosal HPV DNA in patients with extragenital Bowen's disease (n = 30), squamous cell carcinoma (n = 11), bowenoid papulosis (n = 9), verrucous carcinoma (n = 1), actinic keratosis (n = 5), and basal cell carcinoma (n = 5).

Anogenital malignancies and premalignancies are an important personal/public health problem due to their effects on individuals' physical, mental, and sexual health. Also, due to their etiological association with human papillomavirus (HPV) infection, anogenital malignancies and premalignancies constitute an immense public health burden. In addition to HPV infection, immunosuppression, HIV infection, chronic dermatoses, such as lichen sclerosis, previous radiotherapy and chemotherapy treatments, and smoking, are the other important etiopathologic factors in the development of anogenital malignancies and premalignancies.

Human papillomavirus (HPV) incorporates high-risk HPV (hrHPV) and low-risk HPV (lrHPV) subtypes according to its contribution to oncogenesis. Different HPV subtypes could regulate the cell cycle of infected cells at different levels. To date, the expression of cyclin D1 and cyclin E in Bowenoid papulosis (BP) tissues and its association with HPV infection still remains elusive. Read More

Photodynamic therapy (PDT) with methyl aminolevulinate (MAL) has been suggested as a useful treatment option in a number of skin tumors, other than approved indications, and infections. However, evidence is poor because it is mainly supported by isolated case reports or small case series, often with conflicting results. To assess the effectiveness, tolerability and safety of off-label MAL-PDT in daily clinical practice in 20 Italian hospitals, a retrospective observational study of medical records of patients treated for off-label oncologic and infectious skin conditions was carried out.
