More than 100 types of double-stranded HPV papovavirus have been isolated to date. Many of these have been related directly to an increased neoplastic risk in men and women. Approximately 90% of condyloma acuminata are related to HPV types 6 and 11. These 2 types are the least likely to have a neoplastic potential. Risk for neoplastic conversion has been determined to be moderate (types 33, 35, 39, 40, 43, 45, 51-56, 58) or high (types 16, 18), with many other isolated types. The picture is complicated by proven coexistence of many of these types in the same patient (10-15% of patients), the lack of adequate information on the oncogenic potential of many other types, and ongoing identification of additional HPV-related clinical pathology. For example, bowenoid papulosis, seborrheic keratoses, and Buschke-Löwenstein tumors have been linked to HPV infections though they were previously a part of the differential diagnosis of condyloma acuminata. Bowenoid papulosis consists of rough papular eruptions attributed to HPV and is considered to be a carcinoma in situ. The eruptions can be red, brown, or flesh colored. They may regress or become invasive. Seborrheic keratoses previously were considered a benign skin manifestation. HPV has been linked to rough plaques indicative of this disease. It has both an infectious and an oncogenic potential. Finally, Buschke-Löwenstein tumor (ie, giant condyloma) is a fungating, locally invasive, low-grade cancer attributed to HPV. PathophysiologyCells of the basal layer of the epidermis are invaded by HPV. These penetrate through skin and cause mucosal microabrasions. A latent viral phase begins with no signs or symptoms and can last from a month to several years. Following latency, production of viral DNA, capsids, and particles begins. Host cells become infected and develop the morphologic atypical koilocytosis of condyloma acuminata. The most commonly affected areas are the penis, vulva, vagina, cervix, perineum, and perianal area. Uncommon mucosal lesions in the oropharynx, larynx, and trachea have been reported. HPV-6 even has been reported in other uncommon areas (eg, extremities). Multiple simultaneous lesions are common and may involve subclinical states as well-differentiated anatomic sites. Subclinical infections have been established to carry both an infectious and oncogenic potential. Consider sexual abuse as a possible underlying problem in pediatric patients; however, keep in mind that infection by direct manual contact or indirectly by fomites rarely may occur. Finally, passage through an infected vaginal canal at birth may cause respiratory lesions in infants. FrequencyUnited StatesAnnual incidence of condyloma acuminatum is 1%. It is considered the most common sexually transmitted disease (STD). Prevalence has been reported to exceed 50%. Highest prevalence and risk is among young adults in the third decade and in older teenagers. A 4-fold or more increase in prevalence has been reported in the last 2 decades. InternationalInternational prevalence has been reported variably. Available data from England, Panama, Italy, the Netherlands, and other developed and underdeveloped countries report HPV infections to be at least as common as in the US. Mortality/Morbidity

Naturally produced proteins with antiviral, antitumor, and immunomodulatory actions. Alpha, beta, and gamma interferons exist and may be administered topically, systemically, and intralesionally. Topical, systemic, and intralesional interferons are not efficacious.
| Drug Name | Interferon alfa-n3 (Alferon N) |
|---|---|
| Description | Alpha interferon has been approved by FDA for injectional use in refractory condyloma acuminata with some possible benefit. Alferon N is interferon alpha-n3, which has been used effectively for this purpose. Recurrence rate of 20-40% exists with intralesional interferon, but recurrence rate after successful treatment is lower than with other treatment modalities. Additionally, intralesional interferon is expensive and requires repeat office visits. Furthermore, numerous adverse reactions may occur, including myalgias, fever, chills, GI symptoms, transient leukopenia, thrombocytopenia, LFT abnormalities, serum lipid abnormalities with intramuscular interferon, and theoretical risk of viral transmission with natural interferon products. Viral symptoms do abate with time, and all adverse effects resolve once therapy is stopped. Viral symptoms can be treated with acetaminophen or NSAIDs in the interim. |
| Adult Dose | Administer interferon alpha-n3 250,000 U/wart intralesionally twice/wk for up to 8 wk; not to exceed 2.5 million U per treatment session |
| Pediatric Dose | <18 years: Not recommended >18 years: Administer as in adults |
| Contraindications | Documented hypersensitivity; anaphylactic sensitivity to mouse immunoglobulin, egg protein, or neomycin; cardiac or renal impairment |
| Interactions | Theophylline may increase interferon alpha toxicity; cimetidine may increase antitumor effects; zidovudine and vinblastine may increase toxicity of interferon alpha |
| Pregnancy | C - Safety for use during pregnancy has not been established. |
| Precautions | Caution in brain metastases, severe hepatic or renal insufficiencies, seizure disorders, multiple sclerosis, compromised CNS, or debilitating conditions (eg, cardiovascular disease, severe pulmonary disease, diabetes mellitus with ketoacidosis, coagulation disorders, severe myelosuppression, seizure disorder) |

A human papillomavirus vaccine is now available for prevention of HPV-associated dysplasias and neoplasia including cervical cancer, genital warts (condyloma acuminata), and precancerous genital lesions. The immunization series should be completed in girls and young women aged 9-26 years.
| Drug Name | Papillomavirus vaccine (Gardasil) |
|---|---|
| Description | Quadrivalent human papillomavirus (HPV) recombinant vaccine. First vaccine indicated to prevent cervical cancer, genital warts (condyloma acuminata), and precancerous genital lesions (eg, cervical adenocarcinoma in situ; cervical intraepithelial neoplasia grades 1, 2, and 3; vulvar intraepithelial neoplasia grades 2 and 3; vaginal intraepithelial neoplasia grades 2 and 3) due to HPV types 6, 11, 16, and 18. Vaccine efficacy mediated by humoral immune responses following immunization series. |
| Adult Dose | < 26 years: 0.5 mL IM administered as 3 separate doses; administer second and third doses 2 and 6 mo after first dose, respectively >26 years: Not established |
| Pediatric Dose | <9 years: Not established >9 years: Administer as in adults |
| Contraindications | Documented hypersensitivity |
| Interactions | Immunosuppressive therapies (eg, irradiation, antineoplastic agents, corticosteroids) may decrease immune response to vaccine |
| Pregnancy | B - Usually safe but benefits must outweigh the risks. |
