Background

Condylomata acuminata, commonly known as genital warts, is a sexually transmitted infection (STI) caused by certain strains of the human papillomavirus (HPV). HPV is a group of viruses that can infect the genital and anal areas, as well as the mouth and throat.  

The primary cause of genital warts is infection with HPV, particularly strains 6 and 11. These strains are considered low-risk and are not associated with an increased risk of cancer. 

Genital warts often appear as small, flesh-colored bumps or growths in the genital or anal area. They can be raised or flat and may occur singly or in clusters.  

Epidemiology

HPV is one of the most common sexually transmitted infections globally. The prevalence of HPV infection varies across populations, with higher rates seen in sexually active individuals. 

Both men and women can develop genital warts, and the prevalence is generally similar in both genders. Genital warts are primarily transmitted through sexual contact, including vaginal, anal, and oral sex. 

Risk factors for acquiring genital warts include having multiple sexual partners, engaging in unprotected sex, and a history of other sexually transmitted infections. 

Anatomy

Pathophysiology

Genital warts are primarily transmitted through direct skin-to-skin contact during sexual activity. HPV enters the body through microabrasions or breaks in the skin or mucous membranes of the genital, anal, or oral areas. 

The virus enters the host cell and establishes a productive infection, leading to the replication of viral DNA. The virus completes its life cycle in the differentiated layers of the epithelium, leading to the production of viral particles. 

HPV has evolved mechanisms to evade the immune system, allowing it to establish persistent infections. The virus can interfere with host immune responses, making it challenging for the body to clear the infection. 

Etiology

Genital warts are primarily caused by infection with HPV, a group of DNA viruses. HPV is highly prevalent, and there are over 100 known types, with some affecting the genital and anal areas. 

These types are considered low risk because they are not associated with an increased risk of cancer, unlike high-risk HPV types that are linked to cancers such as cervical cancer. 

HPV is primarily transmitted through direct skin-to-skin contact, usually during sexual activity. Transmission can occur through vaginal, anal, or oral sex, and the virus can be passed even when there are no visible warts. 

The virus infects basal epithelial cells, which are found in the outer layer of the skin and mucous membranes. 

Genetics

Prognostic Factors

The immune system plays a crucial role in controlling and clearing HPV infections, including those causing genital warts. 

Individuals with compromised immune systems, such as those with HIV or on immunosuppressive medications, may experience more persistent or recurrent infections. 

Clinical History

Age Group:  

Genital warts are frequently diagnosed in individuals who are sexually active during their late teens and early twenties. 

Genital warts are primarily transmitted through sexual contact, including vaginal, anal, and oral sex. 

Individuals become more sexually active during their late teens and early twenties, leading to an increased risk of exposure to HPV. 

Physical Examination

• Visual Inspection: Genital warts can vary in appearance, ranging from small, flesh-colored bumps to larger, cauliflower-like growths. 
• Location of Warts: Genital warts can appear on various anatomical sites, including the penis, scrotum, vulva, vagina, cervix, anus, and perianal region. 
• Size and Texture: The provider assesses the size, texture, and morphology of the warts. 
• Internal Examination (for Women): In women, the healthcare provider may perform an internal examination, including a speculum examination of the vagina and cervix, to check for the presence of warts in the vaginal canal or on the cervix. 

Age group

Associated comorbidity

In pregnant women, genital warts can pose certain risks, especially if the warts are present in the genital or perianal area. 

In rare cases, the presence of large warts may necessitate interventions during childbirth to prevent obstruction of the birth canal. 

While Condylomata acuminata itself is not directly linked to HIV transmission, the presence of genital warts may increase the risk of HIV acquisition or transmission in individuals who are also at risk for HIV. 

Associated activity

Acuity of presentation

For individuals who do develop visible warts, the onset can be relatively rapid after exposure to the human papillomavirus (HPV). 

Warts may appear within weeks or months of acquiring the infection. The acuity may also depend on the location and size of the warts. Warts in more visible or sensitive areas may prompt individuals to seek medical attention sooner. 

The individual’s immune response plays a significant role in the acuity of genital warts. Those with a robust immune response may clear the infection more effectively or experience a milder presentation. 

Differential Diagnoses

• Molluscum Contagiosum: Molluscum contagiosum is a viral skin infection caused by the poxvirus. 
• Herpes Simplex Virus (HSV) Infection: Genital herpes caused by HSV may present with painful sores, blisters, and ulcers in the genital and anal areas. 
• Seborrheic Keratosis: Seborrheic keratosis is a non-cancerous skin growth that can sometimes be mistaken for warts. 
• Lichen Planus: Lichen planus is an inflammatory skin condition that can affect the genital and anal areas. 
• Syphilis: Early syphilis can present with painless sores or ulcers (chancre) in the genital area. 
• Contact Dermatitis: Contact dermatitis may cause redness, itching, and skin irritation in the genital area. 
• Hemorrhoids: Hemorrhoids are swollen blood vessels in the rectal and anal area. They can cause discomfort, itching, and the appearance of lumps around the anus.

Treatment Paradigm

• Cryotherapy: Cryotherapy involves freezing the warts using liquid nitrogen.  
• Electrosurgery and Laser Therapy: Electrosurgery and laser therapy involve the removal of warts using an electrical current or laser. 
• Surgical Excision: Surgical excision involves cutting off the warts with a scalpel. It may be considered for larger or resistant warts. 
• Intralesional Injection: Intralesional injection of antiviral drugs, such as interferon, directly into the warts may be considered in certain cases. 
• Follow-Up and Monitoring: Regular follow-up visits are important to monitor treatment progress, evaluate for recurrence, and assess for potential complications.

• Safe Sexual Practices: The most common mode of transmission for genital warts is through sexual contact. Practicing safe sex, including the consistent use of condoms, can reduce the risk of HPV transmission. 
• Vaccination: HPV vaccination is a key preventive measure. The HPV vaccine provides protection against certain HPV types, including those associated with genital warts. 
• Regular Screenings: Routine screenings for cervical cancer in women, such as Pap smears and HPV testing, are essential for early detection and management of HPV-related conditions. 
• Partner Communication: Individuals with genital warts should inform their partners about the condition to facilitate informed decision-making. 
• Avoidance of Smoking: Smoking has been associated with an increased risk of persistent HPV infection and the development of complications. 

Use of an immune response modifiers

• Imiquimod: It is an immune response modifier that stimulates the production of cytokines, enhancing the body’s immune response against HPV-infected cells. 

Use of topical antimitotic agents

Podofilox: It is a topical antimitotic agent that interferes with cell division, leading to the death of HPV-infected cells. 

Use of Interferon

Interferon: Interferon is a protein with antiviral properties that may be injected directly into the warts (intralesional injection) to stimulate the immune system’s response.

• Diagnosis Phase: The process begins with a clinical evaluation by a healthcare provider. The diagnosis is often based on the visual inspection of genital and anal areas to identify characteristic lesions. 
• Medical Interventions: Depending on the location, size, and number of warts, various medical interventions may be recommended. This can include topical medications (e.g., imiquimod, podofilox), procedural interventions (e.g., cryotherapy, electrosurgery), or a combination of treatments. 
• Monitoring and Follow-Up: After treatment, regular follow-up visits are scheduled to monitor the progress of treatment, assess for recurrence, and address any new lesions. 
• Proper Partner Communication: Open communication with sexual partners about one’s sexual health, including the presence of genital warts, is essential. 
• Healthier Lifestyle: Maintaining a healthy lifestyle, including a balanced diet, regular exercise, and avoiding smoking, can support the overall immune system. 
• Counselling Phase: The emotional and psychological impact of genital warts should not be overlooked. Counselling and support may be provided to help individuals cope with the diagnosis, address concerns, and manage any associated stigma.
