<s>[INST] Hello, I have a rather embarrassing question. I was diagnosed with molluscum contagiosum aka water warts when I was about 8 years old, as did my friend. Probably from sharing towels. We both had it in the genital area, particularly around the anus. I was prescribed acid stuff that got rid of most of it. However, it is ten years later, and I still have one directly on my anus. It causes a considerable amount of distress. I am wondering how it could not be gone. Also, from time to time, small, flattened bumps appear on my buttocks.  Could you please help? [/INST] Hello, Welcome to Chat Doctor, Wart which is painless and itching are the classical of Congenital Wart or Condyloid Alumina, which is caused by Human Papillomavirus (HPV). Human Papillomavirus (HPV) infection can be transmitted to the partner as this is a sexually transmitted disease. This should be diagnosed by physical examination and PAP smear of the scrapping of the wart and confirmed by Polymerase Chain Reaction (PCR). The treatment for this condition includes1. Cryotherapy- which should be done in the hospital.  2. Local application of 0.5% solution of podophyllin, which should be applied twice daily for 3 days and nothing should be applied for next 4 days (7 days cycle). This cycle should be continued for 4 weeks.3. Local application of 5% Imiquimod cream for 3 times in a week for 16 weeks (4 months). Thank you. </s>
