Viral infections affect the skin causing lesions that cause different symptoms. Human papillomavirus causes rough, eruptions on the skin which are called warts. They are benign growths commonly seen on hands, feet, face, genitals and knees. The virus enters the skin through cuts or broken edges of the skin. Children, elderly people and people affected with low immunity are prone to get an infection that causes warts. Genital warts are contagious and often get transmitted through sexual intercourse, using contaminated towels, essential routine materials, nail-biting and shaving.

It is easy to identify a wart by physical visual examination. They appear dome-shaped or as tiny small eruptions and are skin coloured, grey, brown or black in colour. Usually, these warts are asymptomatic or may cause minor discomfort and pain.  A biopsy is done through excision of the growth to detect the human papillomavirus. Stubborn warts need a surgical procedure to remove them.

Surgical excision of genital warts is done using a scalpel, scissors or curette. Excision of warts is cutting it from the skin to which it is firmly attached. Warts that are painful and cancerous require excision to prevent the spread of growth to distant parts of the body. Surgical excision of warts is done by an experienced skilled dermatologist using only local anaesthesia.

Shave removal excision is done on raised, elevated warts with a sharp razor. The edges resolve and do not require sutures. It causes minimal redness of surrounding skin.

Snip excision of warts is done by prior injecting local anaesthesia. The growth is pulled from the surface of the skin using forceps. Then a curved scissor is used to excise the growth from beneath its edge. Genital warts on the penis, anus and vagina are removed by laser or loop electrosurgical excision. It is done in the outpatient surgery centre. The warts are excised using a scalpel after giving local anaesthesia to patients and edges are then sutured. Patients can continue with routine activities after a brief recovery period of two to three days.
