Filter by:Acrochordon, or soft fibroma, is a common benign skin tumor which is generally regarded as a sign of cutaneous aging or as a reaction to friction since it occurs in the intertriginous areas. Recent studies have shown the presence of human papillomaviruses, especially the mucosal types, on some of the intertriginous lesions. This study is to analyze the different clinical presentations of acrochordon and correlate them with pathologic and molecular human papillomavirus findings. Further goal is to improve the ability to differentiate acrochordon and its possible prevention and treatment. Also, it may have an implication on the transmission and prevention of cervical carcinoma.
Human papillomavirus (HPV)-infection belong to the most common sexually transmitted diseases worldwide. HIV-infected men having sex with men /MSM) are strongly associated with a higher prevalence of genitoanal HPV-infection, and perianal HPV-infections have been detected in up to 90% of HIV-positive men. The data concerning the incidence of oral HPV-infection in HIV-positive men, especially in the era of highly antiretroviral therapy, are conflicting. Thus, this prospective study mainly focuses on the incidence and prevalence of oral HPV-infection, spectrum of HPV-types, and oral high-risk HPV viral load in HIV-positive men.
Human papillomavirus (HPV)-infection belongs to the most common sexually transmitted diseases worldwide. HIV-infected men having sex with men (MSM) are strongly associated with a higher prevalence of genital HPV-infection, a higher incidence of anal intraepithelial neoplasia (AIN), and, consecutively, an increased risk for anal cancer. Since the introduction of highly active antiretroviral therapy (HAART), the incidence of several viral-associated neoplasias has significantly fallen in HIV-infected individuals. At the beginning of the era of HAART, a justified hope existed that genitoanal HPV-related neoplasias would also decrease based on the success of HAART-induced immune restoration. However, HAART seems to have only a small impact on the natural history of AIN as observed in a cohort of HIV-positive MSM before and after the initiation of HAART. As AIN and cancer precursor lesions of the cervix, cervical intraepithelial neoplasia, share distinct clinical similarities, cytologic smear testing for AIN has been recommended to detect and treat early lesions. Thus, this prospective study mainly focuses on the predictive value of HPV-DNA load for the development and clinical progression of AIN in HIV-infected MSM. Moreover, the course of HPV viral load under therapy for anal intraepithelial neoplasia, e.g. topical treatment with imiquimod, will be evaluated. Additionally, immunohistochemical determination of several proliferative biomarkers, as well as cytokines, will be performed.
