Background: Human papillomaviruses (HPVs) are members of the P apillomaviridae family, characterized by circular, double- stranded DNA. T hey exhibit strict tropism, infecting either mucosa or skin. T he role of HPV in the etiology of psoriasis remains unclear. Objectives: T he aim of this study was to determine the presence of alpha human papillomavirus in the skin scrapings of patients with psoriasis and its genotype distributions. Methods: T he study employed a cross-sectional design and included 53 psoriasis patients and 47 healthy controls from December 2020 to May 2021. After DNA isolation from skin scrapings, the L1 gene region of HPV was amplified using MY09/11 and GP5 +/6 + consensus primer sequences. T he HPV genotypes were determined through direct DNA sequence analysis of polym...
