HPV Complication: Children may sustain epithelial tumors on the larynx.
Papillomas are benign epithelial tumors that are caused by infection with the human papilloma virus (HPV). They are the most common benign neoplasms affecting the larynx and upper respiratory tract. Malignant degeneration to squamous cell carcinoma can occur, but is very rare.

Education
• Teaching about transmission and the importance of prevention are critical since there is no cure • HPV vaccines are recommended for 11 and 12-year-old girls and boys—protects against some HPV - three doses over 6 months • Clients may be taught about barrier methods (male/female condoms) and the benefits of limiting numbers of sexual partners to prevent disease transmission • Avoid sexual contact until lesions healed
• trichloroacetic acid (TCA) and bichloroacetic acid (BCA)
◦ Applied to warts ◦ Use petroleum jelly to protect surrounding skin ◦ May be painful upon application Trichloroacetic acid (TCA) is a treatment for genital and anal warts caused by human papillomavirus (HPV). It is a powerful chemical that kills warts by destroying the proteins in the cells. After repeated application, it will cause the warts to shrink and eventually disappear.
podofilox liquid gel
◦ Apply to affected area BID x 3 days weekly x 3 to 4 weeks ◦ Not for use in pregnancy/breastfeeding
Imiquimod (Immune response modifiers).
◦ Not during pregnancy ◦ Immune response modifier Imiquimod is in a class of medications called immune response modifiers. It treats genital and anal warts by increasing the activity of the body's immune system. It is not known exactly how imiquimod cream works to treat actinic keratoses or superficial basal cell carcinoma.
