Genital Warts
● What are Genitial Warts?
Genital warts are a sexually transmitted infection caused by the human papillomavirus (HPV).
They appears as small bumps or cauliflower-like growths around the genital or anal area.
Both men and women can be affected — in women, warts are often found on the vulva, vagina, or cervix; in men, they appear on the penis, scrotum, or around the anus.

● Symptoms
In the early stage, tiny bumps may appear and gradually increase in number or size.
They are usually painless and not itchy, but inflammation may cause redness or minor bleeding.
Although some warts may disappear spontaneously, recurrence is common.

● Diagnosis
Diagnosis is usually made by visual examination.
If necessary, dermoscopy or a small biopsy may be performed to confirm the diagnosis.
Since it is a sexually transmitted infection, testing for other STIs (such as chlamydia, syphilis, or HIV) may also be recommended.

● Treatment
At Shibuya Lily Dermatology Clinic, treatment for genital warts is covered by the Japanese National Health Insurance.
The appropriate method is selected depending on the size, location, and number of lesions.
◎ Topical Therapy
For small lesions, imiquimod cream (Beselna®) can be applied to boost the local immune response and eliminate infected cells.
If the effect is insufficient, or if there are multiple lesions, other treatment options are considered.
◎ Cryotherapy (Liquid Nitrogen Treatment)
The wart is frozen with liquid nitrogen (−196 °C) to destroy HPV-infected cells.
Treatment is usually repeated every 1–2 weeks until the lesion disappears.
A short stinging pain may occur during treatment, but the procedure itself takes only a few minutes.
For those sensitive to pain, a numbing patch (local anesthetic tape, self-paid option) can be applied beforehand.
◎ Surgical Removal (Radiofrequency Electrosurgery)
Under local anesthesia, the lesion can be precisely removed using a radiofrequency scalpel.
This method minimizes bleeding and allows for a cleaner cosmetic result.
It is suitable for larger or resistant lesions, and follow-up is recommended to monitor for recurrence.

● Recurrence and Prevention
Since HPV may remain in surrounding tissues, recurrence can occur even after successful treatment.
Maintaining good immune health and avoiding re-infection from sexual partners are important.
Condom use is recommended, and partners should also be examined and treated if necessary.
HPV vaccination is effective in preventing future infections.
