Genital Warts
A clinically focused clinical guide to anogenital warts for Indian practice, covering respectful examination, important mimics, biopsy triggers, treatment choice, pregnancy, immunocompromise, partner communication, HPV prevention and cancer-screening boundaries.
Summary
Genital warts, also called anogenital warts or condylomata acuminata, are visible epithelial lesions caused predominantly by low-risk human papillomavirus types 6 and 11. They may be flat, papular, filiform, pedunculated or confluent and can occur on genital, perineal, perianal, intra-anal, vaginal, cervical or urethral epithelium. Many are asymptomatic; others itch, bleed, hurt, obstruct a meatus or cause substantial distress. A clinical diagnosis is usually made by careful visual inspection. HPV testing does not confirm that a visible lesion is a wart and does not choose its treatment.
Management is individualized. Observation is reasonable for selected immunocompetent people because lesions may regress, remain stable or enlarge. When treatment is wanted, choice depends on site, size, number, pregnancy, immune status, cost, privacy, access, clinician experience and patient preference. Patient-applied and clinician-administered options have different safety requirements; none reliably eradicates latent HPV, and recurrence is common. Atypical, indurated, fixed, pigmented, ulcerated or bleeding lesions require biopsy consideration, especially with immunosuppression or treatment failure.
The diagnosis must never be used to infer infidelity or the timing of infection. Current partners may already share HPV without visible disease. Condoms reduce but do not eliminate transmission because uncovered skin can carry HPV. Vaccination prevents new vaccine-type infection but does not treat existing warts. Cervical screening follows the applicable national programme and individual risk; external warts alone are not a reason for indiscriminate HPV testing or more frequent cytology.
How Common Is It?
HPV infection is extremely common, while the proportion of infected people who develop clinically visible warts is much smaller. CDC guidance states that about 90% of anogenital warts are attributable to non-oncogenic types 6 or 11. Coinfection with oncogenic types can occur, however, so the presence of a benign-appearing wart does not prove that a person has no separate high-risk HPV infection. Equally, the low-risk types responsible for most warts should not be described to patients as inevitable cancer precursors. That distinction reduces fear without weakening appropriate screening or biopsy.
WHO describes HPV as a widespread sexually transmitted infection that most sexually active people acquire at some time, usually without symptoms, and notes that immune control occurs in most people. Visible-wart frequency varies by age, sexual networks, immune status, vaccination coverage, access to care and surveillance method. Clinic attendance data underestimate people who self-treat or do not seek care, whereas self-reported surveys may misclassify normal variants. A single current Indian national prevalence figure should therefore not be invented from a local clinic series.
Population rates of genital warts have fallen in settings with high coverage of HPV vaccines that include types 6 and 11. India has large regional variation in vaccine availability, price, awareness, screening and STI-service access. For an individual consultation, prevalence is less useful than lesion morphology, site, immune status, pregnancy, other STI risks and the person's goals. Stigma also affects measured burden: fear about confidentiality, relationships, gender identity or sexual orientation can delay presentation.
Risk Factors
The immediate risk factor is cutaneous or mucosal exposure to wart-causing HPV. Transmission can occur during vaginal, anal or oral sex and through close genital skin contact even when penetrative sex has not occurred and no wart is visible. New or multiple partners and inconsistent barrier use increase opportunities for exposure, but a person with one lifetime partner may still acquire HPV. Condoms lower risk but cannot cover every infectious surface. Autoinoculation and nonsexual acquisition are sometimes considered in children, yet anogenital lesions in a child require careful specialist safeguarding assessment rather than an automatic conclusion about route.
Impaired cellular immunity changes presentation and outcome. People living with HIV, transplant recipients and those using significant immunosuppression may develop larger, more numerous or recalcitrant lesions and more frequent recurrence. Suspicious squamous lesions can resemble warts in these groups, lowering the threshold for biopsy. Smoking is associated with persistent HPV-related disease, while coexistence of another STI can reflect shared exposure. Pregnancy may make lesions enlarge or become friable because of hormonal and immune changes; this affects treatment safety but does not by itself require caesarean birth.
Vaccination status modifies future acquisition risk but is not a diagnostic test. Previous warts do not remove potential benefit from prevention of types not yet acquired when the person remains eligible under an evidence-based schedule. Shaving trauma and irritation can make lesions more noticeable or spread them locally, but ordinary hygiene failure is not the cause. Risk counselling should avoid blame and should ask about access to confidential services, pregnancy possibility, medicines, allergies and previous destructive treatments.
Diagnosis
History
Ask when lesions were first noticed, their rate of change, previous episodes and treatments, and whether there is itching, pain, bleeding, discharge, dysuria, dyspareunia, altered urinary stream or bowel symptoms. Establish all affected sites without assuming sexual practice. A confidential, nonjudgmental sexual history covers current partners, types of contact, barrier use, contraception, pregnancy possibility, STI history and testing preferences. Ask about HIV status or testing, transplant history, corticosteroids or other immunosuppression. Document systemic symptoms, rash elsewhere, oral lesions, weight loss and psychosocial impact. Do not attempt to date acquisition from lesion onset.
Examination
With informed consent, privacy and a chaperone according to policy, inspect in good light. Describe number, size, surface, colour, base, distribution and tenderness rather than simply writing “warts.” Examine adjacent genital and perianal skin; consider digital anal examination or anoscopy for external anal lesions when indicated and within competence. Cervical, vaginal, urethral or intra-anal lesions need appropriate equipment and expertise. Palpate suspicious lesions for induration or fixation and look for ulceration, spontaneous bleeding, pigmentation, nodes, discharge and signs of other dermatoses or STIs.
Investigations
Typical lesions require no laboratory confirmation. Do not use an HPV test to diagnose a wart because a result neither proves lesion identity nor guides treatment. Biopsy is indicated or strongly considered for atypical pigmentation, induration, fixation, ulceration or bleeding; uncertain diagnosis; worsening during therapy; failure of appropriate treatment; or suspicious disease in an immunocompromised person. Offer consent-based HIV testing and syphilis testing, with other site-directed STI tests based on history, symptoms and local protocols. Pregnancy testing is appropriate when it changes treatment selection.
Differential Diagnosis
Normal anatomy is a frequent source of anxiety. Pearly penile papules are uniform, smooth papules arranged symmetrically around the corona; vestibular papillomatosis consists of soft, symmetrical projections with separate bases. Fordyce spots, skin tags and prominent sebaceous glands lack the irregular verrucous pattern of typical warts. Molluscum contagiosum produces dome-shaped, often umbilicated papules. Seborrhoeic keratoses may be waxy or pigmented, while benign nevi and angiokeratomas have different surface and vascular features. Dermoscopy can assist a trained clinician but does not replace biopsy when malignancy is possible.
Infection mimics matter. Condylomata lata of secondary syphilis are broad, moist papules and may accompany generalized rash, lymphadenopathy or other signs; serology is required. Herpes usually produces painful vesicles or erosions rather than persistent papillomatous growths. Scabies, folliculitis and candidal inflammation can cause itch but have distinct morphology. Lichen planus, lichen sclerosus, psoriasis and contact dermatitis can produce plaques, fissures or architectural change and should not be repeatedly treated with wart chemicals.
Premalignant and malignant lesions are the critical exclusions: vulval, penile or anal intraepithelial neoplasia; Bowen disease; bowenoid papulosis; verrucous carcinoma; and invasive squamous cell carcinoma. Pigmentation, induration, fixation, ulceration, irregular bleeding, progressive enlargement, pain, nodes, immunosuppression or nonresponse lowers the threshold for tissue diagnosis. Giant condyloma can be locally destructive. Cervical lesions require specialist evaluation and exclusion of high-grade squamous intraepithelial disease before destructive treatment.
Management
Begin by confirming the lesion, explaining its benign usual biology and asking what matters most: symptom relief, appearance, privacy, speed, pregnancy planning, cost or avoiding pain. Observation is acceptable for selected people because warts may regress spontaneously, but provide a review plan and clear biopsy triggers. No method is universally best. Treatment removes visible lesions; it does not prove clearance of HPV or guarantee that transmission and recurrence have ended. Shared decisions should account for anatomic site and whether the person can see and safely reach every lesion.
Patient-applied options for accessible external warts include imiquimod, podofilox or podophyllotoxin, and sinecatechins where locally approved and available. A clinician should identify target lesions and demonstrate application. Clinician-administered options include cryotherapy, careful trichloroacetic acid application, and surgical removal by an appropriately trained practitioner. Large, extensive, obstructive, intraurethral, intra-anal, vaginal or cervical disease usually needs specialist-led treatment. Combining modalities is sometimes practised, but evidence on benefits and harms is limited. Review response and adverse effects rather than continuing an ineffective course indefinitely.
In pregnancy, avoid podofilox or podophyllotoxin, podophyllin and sinecatechins; CDC advises avoiding imiquimod until more human data are available. Cryotherapy or selected clinician-administered removal may be considered after obstetric review. Caesarean birth is not performed solely to prevent infant HPV; it is reserved for usual obstetric reasons or when warts obstruct the outlet or would cause excessive bleeding. In HIV or other immunosuppression, standard modalities remain usable, but expect poorer response, check adherence and reconsider biopsy sooner.
Prescribing Information
Prescribing must be product-specific because concentrations and instructions differ. Imiquimod is a patient-applied immune-response modifier for selected external lesions; local erythema, erosion, burning and ulceration can occur. It must not be placed internally or on unintended normal skin, and the exact formulation determines schedule and duration. Podofilox or podophyllotoxin is cytotoxic and requires a defined treatment area, limited quantity and treatment-free intervals; it is contraindicated in pregnancy. Sinecatechins can cause marked local reactions, has limited evidence in immunocompromised people and pregnancy, and may not be locally available. These medicines can weaken barrier contraceptive products while present on the skin.
Trichloroacetic acid is clinician-administered. Its low viscosity permits spread onto normal tissue, causing chemical burns, so only a small amount is applied to each lesion and allowed to dry. Cryotherapy causes pain, necrosis and blistering; excessive depth increases pigment change and scarring, while inadequate freezing reduces response. Surgical or electrosurgical treatment requires anaesthesia, haemostasis planning, infection precautions, training and smoke evacuation. Podophyllin resin is not a preferred modern regimen because composition varies and severe systemic toxicity has occurred; it must never be casually substituted for a standardized patient-applied product.
Check pregnancy, lactation, immune status, lesion site, allergies, previous reactions and local regulatory availability before prescribing. Give written instructions on amount, application, wash-off where relevant, sexual contact while cream is present, handwashing, expected inflammation and when to stop. Severe pain, ulceration, urinary difficulty or systemic symptoms require review. Do not prescribe ordinary hand-wart acids for genital tissue, and do not offer oral antibiotics, antivirals or unregulated corrosive preparations as HPV cures.
When to Refer
Refer urgently for suspected malignancy or high-grade disease: an indurated, fixed, ulcerated, irregularly pigmented, spontaneously bleeding or rapidly enlarging lesion; persistent pain; enlarged nodes; or a lesion that worsens during appropriate therapy. Immunocompromised people with atypical or refractory disease warrant early dermatology, venereology, gynaecology, urology, colorectal or surgical assessment and biopsy planning. Do not keep destroying a lesion whose diagnosis is uncertain. Histopathology must sample the clinically concerning area and the request should state immune status, site and previous treatment.
Cervical warts require specialist evaluation, including exclusion of high-grade squamous intraepithelial lesion before treatment. Intra-anal disease should be managed with a clinician experienced in anal examination and treatment; urethral or meatal disease causing altered flow needs urological input. Extensive, confluent, recurrent, giant or anatomically complex warts may require surgery or laser in a service with anaesthesia, haemostasis and smoke-control capability. Pregnancy with bulky, friable or obstructive disease needs obstetric and appropriate procedural input.
Routine referral is also appropriate when first-line treatment is ineffective after a complete correctly used course, adverse effects prevent continuation, diagnosis remains disputed, or distress is severe. Offer linkage to confidential STI services for HIV, syphilis and other indicated testing rather than treating lesions in isolation. In India, referral options include designated STI/RTI clinics, NACO-linked services, medical colleges and specialist public or private clinics. Confirm local availability, costs, specimen pathways and follow-up instead of assuming uniform access.
Red Flags
Red flags are morphological, systemic and functional. Pigmentation that is irregular or new, induration, fixation to deeper tissue, ulceration, spontaneous bleeding, rapid growth, destructive change, persistent pain or regional lymphadenopathy may signal intraepithelial neoplasia or invasive cancer. Atypical lesions in a person living with HIV, after transplant or on significant immunosuppression require particular caution. Treatment failure is not proof of resistance: revisit the diagnosis, application technique, adherence and need for biopsy before escalating destruction.
Acute urinary retention, severe meatal obstruction, uncontrolled haemorrhage, secondary infection with systemic illness, or severe treatment-associated chemical burn needs prompt assessment. Following a patient-applied treatment, extensive erosion, intolerable pain or application to internal mucosa should trigger cessation and clinical review. After a procedure, fever, spreading erythema, escalating pain or unexpected bleeding may indicate a complication. Suspected sexual assault or safeguarding concern requires a trauma-informed pathway and must not be managed as a lesion-only encounter.
In pregnancy, warts obstructing the pelvic outlet or likely to bleed excessively during birth require obstetric planning; visible lesions alone are not an indication for caesarean delivery. Cervical bleeding, postcoital bleeding, foul discharge or a visible abnormal cervix must not be attributed automatically to external warts. Jaundice, weight loss or generalized rash suggests another systemic process. Psychological crisis, coercion, fear of partner violence or threatened self-harm after an STI diagnosis is also urgent and requires private safety assessment and support.
Indian Clinical Context
NACO's HIV care and STI/RTI guidance places anogenital wart care within integrated services that include sexual-history taking, syndromic assessment, HIV and syphilis testing, counselling, condom access and referral. This matters because a wart visit can be a practical entry point to preventive care, but testing must remain consent-based and confidential. Public pathways differ by district. A clinician should identify the actual designated STI/RTI clinic, integrated counselling and testing centre, pathology service and specialist referral route rather than giving generic instructions that may be inaccessible.
Availability and approval of imiquimod, podophyllotoxin, sinecatechins, cryotherapy and procedural care vary. Brand substitution can create dangerous concentration errors, particularly between podophyllotoxin and podophyllin resin or among acid preparations. Record the generic name, strength, route, treatment surface and duration. Out-of-pocket cost, repeated travel, loss of wages, need for privacy and gender-concordant examination may determine whether a theoretically effective plan is usable. Teleconsultation can support counselling but cannot reliably characterize an atypical pigmented or indurated lesion.
HPV vaccination and cervical screening should be discussed without implying that wart treatment prevents cancer. WHO recommends vaccination before sexual exposure and recognizes schedules that vary by age and immune status; clinicians must use the current Indian programme or licensed product schedule. People with a cervix should continue screening under current MoHFW or state guidance, including HIV-specific pathways where applicable. Care should be inclusive of women, men, transgender people and sexual minorities, use understandable language, and explicitly counter myths about hygiene, morality and certain infidelity.
NMC Competency Mapping
This topic integrates NMC undergraduate learning across Dermatology and Venereology, Microbiology, Community Medicine, Obstetrics and Gynaecology, Internal Medicine, Surgery and AETCOM. A learner should describe HPV structure and epithelial tropism, distinguish low-risk wart-associated types from oncogenic types, recognize common lesion morphologies and construct a differential that includes normal variants, syphilis, molluscum and squamous neoplasia. The learner should know why HPV testing is not a diagnostic test for a visible wart and when histopathology becomes necessary.
Clinical competence includes taking a confidential sexual history, obtaining examination consent, using a chaperone appropriately, describing lesions precisely, assessing pregnancy and immunosuppression, and offering consent-based HIV, syphilis and site-directed STI testing. Learners should compare observation, patient-applied treatments and clinician-administered destruction; recognize contraindications in pregnancy; and explain recurrence without labelling the person as reinfected or nonadherent. Cervical, intra-anal, urethral and malignant-appearing lesions must trigger appropriate referral rather than unsupported independent procedures.
Communication competence is central. The learner should explain that lesion timing cannot identify when or from whom HPV was acquired, support voluntary partner discussion, maintain confidentiality and address stigma. Prevention teaching distinguishes condoms' partial protection, vaccination's preventive role and cervical screening's separate purpose. Reading this guide does not certify genital examination, biopsy, cryotherapy, acid application, surgery or pregnancy management. Each needs supervised skills teaching, infection-control training, local formulary knowledge and documented competence.
Key Exam Pearls for NEET PG
Most anogenital warts are caused by low-risk HPV 6 and 11; oncogenic HPV types are associated with anogenital and oropharyngeal cancers but are not the usual cause of benign condylomata. Diagnosis of a typical wart is clinical. Do not choose HPV DNA testing as confirmation because it does not establish that the lesion is a wart or alter its treatment. Biopsy an atypical pigmented, indurated, fixed, bleeding or ulcerated lesion, and consider biopsy for uncertainty, worsening, nonresponse or immunocompromise. Condylomata lata suggest secondary syphilis and need appropriate testing.
Management depends on site and patient factors. Patient-applied options for external accessible lesions include imiquimod, podofilox or podophyllotoxin, and sinecatechins; clinician-administered options include cryotherapy, trichloroacetic acid and surgical removal. There is no single superior modality, treatment does not guarantee viral eradication, and recurrence is frequent, especially early after treatment. External anal warts should prompt consideration of intra-anal disease. Cervical warts require specialist evaluation and exclusion of high-grade disease; intra-anal lesions need experienced specialist management.
In pregnancy, podofilox or podophyllotoxin, podophyllin and sinecatechins are avoided, and CDC advises avoiding imiquimod because human data remain limited. Caesarean birth does not reliably prevent juvenile respiratory papillomatosis and is not performed solely for warts. HIV and other immunosuppression cause more extensive, refractory and recurrent disease, but do not automatically create a different basic treatment list. Vaccination prevents new infection; it does not treat established lesions. External warts alone do not justify extra cervical screening beyond the applicable programme.
Frequently Asked Questions
Does a new genital wart prove that a partner was recently unfaithful?
No. HPV can be shared without visible signs, and a wart may appear months or years after acquisition. Examination cannot date infection or identify its source. Counselling should avoid accusations, support voluntary and safe partner communication, and explain that current partners may already share HPV even when neither has other symptoms.
Will removing every visible wart cure HPV and stop all future transmission?
Not reliably. Treatment can remove lesions and improve symptoms or distress, but it does not prove eradication of HPV from surrounding epithelium. Recurrence is common, particularly during the first months. Condoms reduce but do not eliminate transmission, and no post-treatment test certifies that a person can no longer transmit HPV.
Should someone with external genital warts have an HPV test or extra cervical smears?
HPV testing is not recommended to diagnose a visible wart because it neither confirms lesion identity nor selects treatment. A person with a cervix should continue screening according to the current national or risk-specific programme. External warts alone do not require more frequent cytology, although an abnormal cervix or cervical wart needs specialist evaluation.
Can genital warts be treated safely during pregnancy?
Some clinician-administered treatments may be considered after obstetric assessment, but podofilox or podophyllotoxin, podophyllin and sinecatechins should not be used, and CDC advises avoiding imiquimod until more human data exist. Caesarean birth is not performed solely to prevent HPV transmission; obstruction or excessive bleeding risk may change delivery planning.
