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.
