Lesson

Separate Infection, Warts, and Precancer

HPV is a family of epithelial viruses with different clinical consequences. The types causing most visible warts are not the types driving most HPV related cancers.

What to learn
  • Types 6 and 11
  • Oncogenic types
  • Epithelial persistence
  • Spontaneous clearance
  • Subclinical infection

Identify the wart associated types

About 90 percent of anogenital warts are caused by nononcogenic HPV types 6 or 11. Coinfection with oncogenic types can still occur.

Understand persistence

Most HPV infections become undetectable spontaneously. Persistent infection with oncogenic types creates the important precancer and cancer risk.

Define the target of therapy

Wart treatment removes visible lesions and can improve symptoms or distress. It does not prove eradication of subclinical infection or eliminate recurrence.

Keep screening separate

Cancer screening detects pathologic change rather than typical external warts. Vaccination and screening remain important after wart treatment.

Lesson

Know When a Wart Needs Tissue Diagnosis

Typical flat, papular, or pedunculated lesions are diagnosed visually. Atypia, uncertainty, immune compromise, or treatment failure lowers the threshold for biopsy.

What to learn
  • Visual diagnosis
  • Atypia
  • Biopsy
  • Condyloma lata
  • HPV testing boundary

04ConfirmSecure the next decision

Connect epithelial biology, lesion anatomy, treatment fit, prevention, and follow-up.

Diagnose the typical presentation

Record lesion number, size, surface, distribution, symptoms, and internal versus external location. Typical warts do not require HPV testing.

Biopsy suspicious disease

Biopsy pigmented, indurated, fixed, bleeding, or ulcerated lesions, and consider biopsy when diagnosis is uncertain, disease worsens, or standard therapy fails.

Protect the differential

Condyloma lata from secondary syphilis and benign or malignant growths can resemble HPV warts. Use history, examination, serology, and tissue when needed.

Do not misuse HPV tests

Oncogenic HPV assays support cervical screening and follow-up questions. They do not confirm a wart, screen a partner, or function as a general STI test.

  • Patient preference
  • Anatomic fit
  • Access
  • Response checkpoint

04ReassessSecure the next decision

Connect epithelial biology, lesion anatomy, treatment fit, prevention, and follow-up.

Offer observation honestly

Untreated warts can resolve, remain unchanged, or increase. A patient with secure diagnosis and low symptom burden can reasonably defer treatment.

Choose the treatment setting

Patient applied therapy requires every target wart to be visible and reachable. Provider treatment fits internal, extensive, inaccessible, or procedure appropriate disease.

Set expectations before treatment

Local inflammation, multiple visits, incomplete clearance, and recurrence are possible with every modality. Combination treatment is sometimes used, but evidence is limited.

Use a response checkpoint

Most responsive lesions improve within about 3 months. Reassess technique, adherence, immune status, diagnosis, adverse effects, and modality when improvement is not substantial.

Use the 5 percent schedule

Apply at bedtime three times weekly for up to 16 weeks. Wash the treated area with soap and water 6 to 10 hours after each application.

Use the 3.75 percent schedule

Apply at bedtime every night for up to 8 weeks, then wash after 6 to 10 hours. Do not interchange the two formulation schedules.

Manage local inflammation

Redness, irritation, induration, erosion, ulceration, vesicles, and pigment change can occur. Severe injury can require a pause, reduced frequency, or a new plan.

Protect barriers and partners

The cream can weaken condoms and vaginal diaphragms and irritate anogenital mucosa. Avoid sexual contact while the product is on the skin.

Cycle podofilox correctly

Apply podofilox 0.5 percent solution or gel twice daily for 3 days, then stop for 4 days. Repeat as needed for no more than four cycles.

Respect podofilox exposure limits

Treat no more than 10 square centimeters and use no more than 0.5 mL per day. Avoid open wounds, excess normal skin, and internal lesions.

Use sinecatechins correctly

Apply sinecatechins 15 percent ointment three times daily until clearance for no more than 16 weeks. Do not wash it off before the next application.

Screen the host before dispensing

Do not use podofilox during pregnancy. Sinecatechins is not recommended in pregnancy, immune compromise, or genital herpes because safety and efficacy are not established.

Apply cryotherapy with trained technique

Thermal cytolysis commonly causes pain, necrosis, and blistering. Local anesthesia can help when lesions are large or numerous.

Use surgery for high burden or one visit clearance

Scissor or shave excision, curettage, laser, and electrosurgery can remove most visible disease at one visit, but recurrence remains possible.

Control procedural plume

Use standard precautions, room ventilation, and local smoke evacuation during procedures that aerosolize tissue.

Apply TCA or BCA precisely

Place a small amount of 80 to 90 percent solution only on the wart and allow white frost. Neutralize or remove excess that spreads to adjacent tissue.

Inspect the anal canal

External anal or perianal warts can coexist with intra-anal lesions. Consider digital examination, standard anoscopy, or high resolution anoscopy.

Protect the cervix

Exophytic cervical warts require specialist consultation and biopsy evaluation to exclude HSIL before treatment.

Protect vaginal tissue

Vaginal options include liquid nitrogen cryotherapy, surgical removal, or TCA or BCA. Do not use a cryoprobe in the vagina because perforation and fistula can occur.

Refer intra-anal disease

Intra-anal warts use provider administered therapy with colorectal specialist involvement. Patient applied external products are not inserted into the anal canal.

04DeliverySecure the next decision

Connect epithelial biology, lesion anatomy, treatment fit, prevention, and follow-up.

Expect more difficult disease with immune compromise

Warts can be larger, more numerous, more recurrent, and less responsive. Atypical or resistant disease warrants a lower biopsy threshold.

Use pregnancy treatment boundaries

Do not use podofilox, podophyllin, or sinecatechins during pregnancy. Imiquimod is generally avoided until more pregnancy data are available.

Expect lesions to change during pregnancy

Warts can proliferate or become friable. Provider treatment or observation depends on symptoms, anatomy, bleeding, and obstetric goals.

Do not promise prevention through cesarean

Cesarean delivery is not performed solely to prevent neonatal HPV. Consider it when warts obstruct the pelvic outlet or vaginal delivery would cause excessive bleeding.

Recommend routine and catch-up vaccination

Start routinely at age 11 or 12, with the option to start at 9. Complete catch-up vaccination through age 26 when not adequately vaccinated.

Use two doses when eligible

Most people starting before age 15 receive doses at 0 and 6 to 12 months. If the doses are less than 5 months apart, give a third dose.

Use three doses when indicated

People starting at age 15 or older and immunocompromised people use 0, 1 to 2, and 6 months. Minimum intervals are 4 weeks, 12 weeks, and 5 months.

Handle adulthood and pregnancy correctly

Use shared decision-making for selected inadequately vaccinated adults ages 27 to 45. Delay doses during pregnancy, but do not test routinely or restart after interruption.

Explain recurrence

Warts can recur after treatment, especially during the first 3 months. Recurrence does not automatically mean a new exposure or failed relationship.

Counsel partners accurately

Current partners often share HPV. Routine HPV testing of partners is not recommended, but examination, vaccination, and testing for other STIs can be appropriate.

Use layered prevention

Condoms reduce but do not eliminate risk because uncovered skin can transmit HPV. Avoid contact while irritating topical products are present.

Preserve long term prevention

Continue recommended cervical and other cancer screening, offer vaccination when eligible, address smoking and immune status, and reassess nonresponse or atypia.
