Warts


This is a very common skin infection caused by the papillomavirus. Today more than 150 types of virus detected by PCR (polymerase chain reaction), and the hybridization of DNA are known. HPV virus is divided into three categories.

mirmigiesThe first category includes types of virus 1, 2, 3, 4 isolated from the skin which are responsible for the appearance of warts. The second category includes the types 6, 11, 16 and 18 which are isolated from the mucous membranes of the genital area and cause genital warts, and the third category includes types 5 and 8, which are isolated from verruciformis epidermodysplasia lesions (genetically transmitted disease) with susceptibility to certain types of HPV. I should note that the types of HPV 16 and 18 in the second category can contribute along with other factors to the cervical cancer risk in high rate. Currently, vaccines are available for prophylaxis of infection by the types of HPV 6, 11, 16 and 18.

The incubation time of warts is large and varies from 1 to 18 months, with a median average of 3.5 months. Depending on the clinical status and location, the warts are divided into common, to smooth and warts on the feet soles.

Common warts occur mainly on the dorsal surface of the hands and fingers, to the legs, but may occur in any part of the body.

They are referred to as sub-circular waves with rough surface 2-10 mm in diameter or greater and are painless. They are most common in childhood and sometimes the heal on their own.

Flat warts: appear mainly on the face and on the dorsal surface of the hands and the legs. These are slightly conceited lesions, of circular or polygonal diameter 1-5 mm or greater and are painless. In some cases, self-healing is noted within a few weeks.

Plantar Warts: Warts are found on the soles as a circular lesion with rough surface surrounded by a horny ring. When the keratin covering the damage is removed with a scalpel, we will observe black spots (like pepper) that are diagnostic and are attributed to small thrombosed vessels. Pain is a characteristic symptom of plantar warts, unlike other wart types. In some cases, there may be self-healing, especially in children while the condition is persistent in people with orthopedic problems or hyperhidrosis. The different diagnosis of the soles warts will be that of calluses where the epidermal ridges extend without being interrupted while the surface remains smooth.

Therapeutically, warts are removed with electrosurgery, cryotherapy or laser.
