Management of intra-anal warts should include consultation with a colorectal specialist. This material may not be published, broadcast, rewritten or redistributed in any form without prior authorization. CDC also lists intralesional interferon, photodynamic therapy, and topical cidofovir as alternative treatments, with more side effects and/or less data on efficacy compared with recommended treatments. Sexual activity is related to the presence of HPV infection and particularly HR-HPV genotypes. Human papilloma virus (HPV) is the most common sexually transmitted infection in the world. The Lowe Staging System (established in 1983) and the tumor, nodes, and metastases classification system are both in use to stage scrotal cancer (Pagliaro, 2016). 51. Combining treatment modalities for condyloma acuminatum. ), (Reports an analysis of a cohort study that enrolled HIV-negative men who have sex with men that showed an association between HPV infection and HIV acquisition. In Black men, 69% of all scrotal tumors are SCC, compared with 31% of all scrotal tumors in white men (Wright et al., 2008). 743-56. 2006. pp. ), (Two-part review focusing on (1) the debate over who should be vaccinated, at what age, and in which populations, and (2) cost-effectiveness of vaccination, the HPV vaccination rograms currently instituted around the globe, efficacy, and safety.). 1 The diagnosis of anogenital lesions can be difficult due to highly variable presentations and the sometimes nonspecific clinical picture. Anogenital Lesions: Kaposi's Sarcoma and Its Mimicks Kaposi's sarcoma (KS) is a low-grade vascular neoplasm associated with human herpes virus-8 (HHV-8) infection, and, in the epidemic form, with the human immunodeficiency virus (HIV). With the use of . Anogenital HPV | IntechOpen Scrotal cancer is rare, with an estimated incidence rate of 0.951.5 per 1,000,000 persons (Verhoeven et al., 2010; Wright et al., 2008). Nieves-Condoy J. F., Acua-Pinzn C. L., Chavarra-Chavira J. L., Hinojosa-Ugarte D., Ziga-Vzquez L. A. (2021). Likewise, VIN can present as undifferentiated basaloid lesions or warty condylomas, and these subtypes are morphological variants because both presentations can often be found on the same lesion (Wakeham et al., 2017). Trichloroacetic acid (TCA) and bichloroacetic acid (BCA) are provider-administered caustic agents that destroy warts by chemical coagulation of proteins. Assembly of HPV virons occurs in the upper layer of the epithelium, from which virions can be released to infect other adjacent tissue and other hosts through sexual contact. Human papilloma virus and genitourinary cancers: A narrative review. scalpel or curettage is an option when small numbers of lesions are present and for exophytic or pedunculated warts. Anal cancer incidence in the United States, 19772011: Distinct patterns by histology and behavior. Scrotal SCC is classified as A1, A2, B, C, or D (Vyas et al., 2014). Similar to the epidemiology of anogenital warts, prevalence of type-specific HPV infection among women aged 1419 years has decreased since HPV vaccination became available, despite low vaccination uptake. Risk factors associated with persistence of HPV infection (again, not limited to HPV-6 or -11) include older age, cigarette smoking or other tobacco use, immunocompromised state (including HIV), nutritional deficiencies, non-use of condoms, presence of other STDs, oral contraceptive use, uncircumcised status among men, and human leukocyte antigen (HLA) polymorphisms. The safety of sinecatechins during pregnancy is unknown. Effectiveness of topical and ablative therapies in treatment of anogenital warts: A systematic review and network meta-analysis. Of the patient-applied topicals, podophyllotoxin is the most effective in achieving complete clearance. No HPV test can determine which HPV infection will clear and which will progress. Anogenital warts (AGWs) (also known as genital warts, condylomata acuminata, condylomas) are benign proliferative lesions caused by human papillomavirus (HPV) types 6 and 11, which are found in >95% of lesions [1, 6]. Clearance of HPV. A Buschke-Lwenstein tumor, also known as giant condyloma acuminatum (GCA), is a highly differentiated anogenital verrucous carcinoma with deep infiltrative growth associated with mucosal HPV infection that is distinct from condylomata acuminata (genital warts) and SCC (Nordsiek et al., 2015). To ensure that patient-applied modalities are effective, instructions should be provided to patients while in the clinic, and all anogenital warts should be accessible and identified during the clinic visit. In condyloma acuminatum, by contrast, multiple papillary projections can arise from an individual base. With either formulation, the treatment area should be washed with soap and water 610 hours after the application. Health care providers should be trained on the correct use of this therapy because overtreatment or undertreatment can result in complications or low efficacy. An episomal maintenance phase then occurs. Download Free PDF SCC is the predominant form of scrotal cancer and the most common form of scrotal malignancy (Vyas et al., 2014). However, most HPV infections are immunologically cleared within a year and do not progress (Bolhassani, 2018). 107-10. Vulvar cancer is rare, but the incidence and death rate has been increasing over recent years to a rate of 2.5 new cases and 0.6 deaths per 100,000 people (Howlader et al., 2018). Most anal cancers are SCC, often caused by a persistent high-risk HPV (HR-HPV) infection. Penile SCC presents as an erythematous, indurated papule/plaque or ulcerations (Marchionne et al., 2017). Spiess P. E., Dhillon J., Baumgarten A. S., Johnstone P. A., Giuliano A. R. (2016). 2010. pp. In men, GCAs are more common (having a 2.7:1 male-to-female ratio), and this ratio is increased in patients less than 50 years old (Trombetta & Place, 2001). Anogenital warts typically respond within 3 months of therapy. Bowenoid papulosis. (Specific section on anogenital warts available at: http://www.cdc.gov/std/tg2015/warts.htm . (Courtesy of Orr Barak, MD, PhD), High-magnification view of the granular layer demonstrates coarse hyaline granules with scattered koilocytic changes (hyperchromatic nuceli with vacuolization).

Large lesions can lead to difficulty with intercourse, vaginal delivery, or defecation. Public health impact and cost-effectiveness of catch-up 9-valent HPV vaccination of individuals through age 45 years in the United States. Association between smoking and genital warts: longitudinal analysis. The medication should not be washed off after use. A small amount should be applied only to the warts and allowed to dry (i.e., develop white frost on tissue) before the patient sits or stands. However, limited data exist regarding the efficacy or risk for complications associated with combination therapy. Common Nonvenereal Genital Lesions - ScienceDirect For the scope of this article, cervical cancer has not been included. However, in certain circumstances, HPV tests can determine whether a woman is at increased risk for cervical cancer. (2017). Condoms might lower the chances of transmitting genital warts if used consistently and correctly; however, HPV can infect areas that are not covered by a condom and might not fully protect against HPV. 73. Sexual assault or abuse should be considered as a potential route of exposure. Howlader N., Noone A., Krapcho M., Miller D., Brest A., Yu M., Ruhl J., Tatalovich Z., Mariotto A., Lewis D., Chen H., Feuer E., Cronin K. (2018). Women who are HIV-positive have a higher prevalence of known HPV-related pathology of the vulva, vagina, and anus as well as higher incidence of HR-HPV in the anus compared with HIV-negative women (Stier et al., 2015). Persons with HIV infection or who are otherwise immunosuppressed are more likely to develop anogenital warts than those who do not have HIV (1231). Women with genital warts do not need Pap tests more often than other women. Cases in which lesions are large and obstructive of other functions, as discussed, are more serious. Genital warts can develop months or years after getting HPV. Anogenital warts occur commonly at certain anatomic sites, including around the vaginal introitus, under the foreskin of the uncircumcised penis, and on the shaft of the circumcised penis. Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. Because genital warts can be sexually transmitted, patients with genital warts benefit from testing for other STDs. Data from studies of human participants are limited regarding use of imiquimod during pregnancy; however, animal data indicate that this therapy poses low risk (431). Not treating condyloma acuminatum is also a reasonable option to consider. Routine vaccination coverage levels are increasing and recommended for females aged 1126 years and males aged 1121 years (Simard et al., 2013). Condyloma Acuminata - StatPearls - NCBI Bookshelf However, the treatment approach should be similar regardless of HIV infection status. Clinicians should inquire about the patients HIV status, including (if positive) viral load and CD4 count, and (if negative) history of HIV testing to determine need for an HIV test. In addition to schools, primary care and outpatient clinics provide clinical opportunities to improve vaccination rates (Hoover & Mayer, 2020). HPV types that cause genital warts can be passed on to another person, even without visible signs of warts. They are caused by human papillomavirus (HPV) genotypes 6 and 11 in >95% of cases. A., Pedersen J. E., Moughan J., Benson A. Some error has occurred while processing your request. These tests are not for detecting other HPV-related problems, nor are they useful in women aged<25 years or men of any age. J Am Acad Dermatol. Dont miss out on todays top content on Dermatology Advisor. Patients with anogenital dermatoses may present to various specialties, including dermatology, vol. Search for Similar Articles Markowitz, LE, Hariri, S, Lin, C. Reduction in human papillomavirus (HPV) prevalence among young women following HPV vaccine introduction in the United States, National Health and Nutrition Examination Surveys, 2003-2010. Radiation therapy combined with chemotherapy (5-fluorouracil, mitomycin, capecitabine, and/or cisplatin) has shown to be successful in treating anal cancer and increasing colostomy-free survival without surgery, as well as advanced-stage anogenital SCCs (Gunderson et al., 2012). Although genital warts can be treated, such treatment does not cure the virus itself. MMWR. Unlike other anogenital lesions, flat atypical superficial VIN 1 lesions are uncommon in the vulva; rather, they present as exophytic condyloma acuminata with low-grade dysplasia (Del Pino et al., 2013). Human papillomavirus vaccination for adults: Updated recommendations of the advisory committee on immunization practices. Brouwer A. F., Eisenberg M. C., Carey T. E., Meza R. (2019). Immunosuppressed persons are more likely to experience condyloma acuminatum. Gynecologic, urologic, or surgical consultation should be considered if condyloma acuminatum are large or involve sensitive anatomic sites. Chapter 13Cervical squamous neoplasia. Moscicki A. vol. Squamous cell carcinomas arising in or resembling anogenital warts might occur more frequently among immunosuppressed persons, therefore requiring biopsy for confirmation of diagnosis for suspicious cases (12351237). The incidence of high-grade cervical, vulvar, or vaginal dysplasia with HPV 31, 33, 45, 52, and 58 among individuals receiving the nonavalent HPV vaccine was 0.5 cases per 10,000 person-years compared with 19.0 cases per 10,000 person-years for the tetravalent vaccines (Huh et al., 2017). Biopsy to exclude high-grade dysplasia should be performed before treatment is initiated. Topical therapies for the treatment of anal high-grade squamous intraepithelial lesions. Kaposi's sarcoma (KS) is a low-grade vascular neoplasm associated with human herpes virus-8 (HHV-8) infection, and, in the epidemic form, with the human immunodeficiency virus (HIV). Sex partners tend to share HPV, even though signs of HPV (e.g., warts) might occur in only one or neither partner. A study of 112 patients also found that HR-HPV-positive cases of VIN had a lower rate of disease progression to cancer than HR-HPV-negative cases. Surgical therapy has the advantage of eliminating the majority of warts at a single visit, although recurrence can occur. HPV testing does not have a role in the clinical evaluation of persons who have, or are concerned about, condyloma acuminatum, since results of such testing would not alter clinical management. vol. Structurally, the HPV genome is housed in a capsid shell composed of major (L1) and minor (L2) structural proteins. The surface of lesions can be verrucous or flat, with the former more common for mucosal lesions. Using international population-based cancer registries between 1983 and 2007, the incidence of anal SCC increased in both men and women in the United States, Canada, most of Europe, and Australia but remained unchanged in Asian countries, which could be attributed to the difference in the prevalence of environmental risk factors that increase the persistence of anal HPV (Islami et al., 2017). Imiquimod 5% cream should be applied once at bedtime, 3 times/week for up to 16 weeks (1217). 86. Histopathologic examination of biopsied tissue can confirm a diagnosis of condyloma acuminatum and/or rule out more concerning diagnoses, such as squamous cell carcinoma or its variants (including verrucous carcinoma) or Bowenoid papulosis. Hernandez B. Y., Barnholtz-Sloan J., German R. R., Giuliano A., Goodman M. T., King J. Those factors make it important to have a discussion with the patient to determine his or her preferences regarding treatment options, and to tailor treatment to those preferences. 2015. pp. Medeiros-Fonseca B., Mestre V.

S., Vakar-Lopez F., Gaivo I., Brito L., Lopes C., Gil da Costa R. M. (2020). For most patients, treatment results in resolution of the warts. Some patients complain of a foul smell emanating from lesions arising in intertriginous areas. In addition, early reports suggest that p16-positive LSIL lesions may be at increased risk for association with, or progression to HSIL. In this instance, referral to a specialist for treatment is recommended. ), Forcier, M, Musacchio, N. An overview of human papillomavirus infection for the dermatologist: disease, diagnosis, management, and prevention. Diagnosed patients are typically in their 60s and 70s, with the highest incidence in the white population and then Black, Hispanic, and Asian populations (Shiels et al., 2015).
