    Human papillomavirus (HPV) is a DNA virus that presents tropism for epithelial cells, causing infections of the skin and mucous membranes. Replication of HPV occurs in the nuclei of squamous cells and its life cycle is directly related to the differentiation program of the host cell. To date, nearly 100 different types of HPV have been characterized and there is a large number of other types that have not been sequenced yet. Besides being responsible for benign lesions of the skin and mucous membranes, HPV is also involved in the development of various mucocutaneous tumors: Bowen's disease, non-melanoma skin cancers and genital carcinomas. This review discusses the characteristics of HPV, malignant and benign mucous and skin manifestations caused by HPV, besides the main methods of detection and typing of the virus.
