  Genital warts 外阴部瘤

  Warts, or condylomata acuminata, are caused by the human papilloma virus (HPV). Up to nine months can pass from the time of infection to the actual development of warts. In women, human papilloma virus can lead to changes in the cervix and to the development of cervical cancer. Therefore, it is important that this condition is diagnosed and treated.

  The symptoms are raised, rough, wart-like growths that may occur singly or in clusters. In men, they are usually found around the head of the penis and tend to be drier. In women, they appear most often around the vaginal opening and may spread to the rectal area. It is also possible for the virus to appear on or near the cervix as whitish, flat-like lesions, usually only detectable through close visual examination of the cervix (colposcopy). In both men and women, lesions may also be present in the mouth and throat. In general, symptoms can intensify if the immune system is weakened, or during pregnancy or if the person has diabetes. The warts are very contagious so safe sex is advisable.

  A diagnosis is made when a characteristic lesion is visible. By swabbing the skin with 5 per cent acetic acid, ‘invisible‘ warts will emerge as white-coloured patches. A GP can treat the warts by freezing and swabbing, but if this does not help the patient may be referred to a genitourinary specialist who can offer more specialised treatment. However, it is important to note that treatment does not always offer a complete cure. For more information, read the page on genital warts.
