Definition
Hiperplasi epidermal Verruca is caused by human papilloma virus (HPV) a particular type. HPV genotypes are divided into separate based on DNA content. Different types of HPV that can infect both the stratum corneum squamous epithelium or mucous membrane layer that has no horns. Appearance of lesions is not only influenced by the type of virus but also by environmental factors and the host.
More than 100 types of HPV that infektion skin and mucous membranes have been identified. Types of HPV that infect the skin will develop into verruca vulgaris. Specific type of high-risk HPV that infect the mucosa tissue in the genital area has a carcinogenic effect. High-risk HPV is also found in the head and neck cancer that develops in the tonsils.
There is also a low-risk types of HPV that cause benign lesions in the genital area, such as genital verruca. Some types of HPV infect the skin and cause verruca at various locations in the body. HPV types cause benign growth, or papilloma on the vocal cords.

This virus can also spread to other parts of the body. For example, it can spread to verruca around nails, lips, and surrounding skin if we verruca often bite on the finger or the nail, or if we like to suck fingers with verruca. If you have the immune system bad, it can develop into a much verruca and difficult to remove (eg in AIDS patients, in patients undergoing chemotherapy, etc.).
