Anogenital Warts (Condyloma Acuminata)
Anogenital warts are a common sexually transmitted infection caused by specific low-risk strains of the Human Papillomavirus (HPV), primarily types 6 and 11.
Clinical Presentation
- Appearance: Soft, fleshy, flesh-colored or hyperpigmented papules. They can be sessile (flat-topped) or pedunculated.
- Morphology: Often described as having a “cauliflower-like” appearance when multiple lesions coalesce.
- Distribution: Perianal region, vulva, perineum, penis, and scrotum.
Management Approaches
| Method | Examples |
|---|---|
| Patient-Applied | Podofilox (0.5% solution/gel), Imiquimod (5% cream). |
| Provider-Administered | Cryotherapy (liquid nitrogen), Trichloroacetic acid (TCA), surgical excision, or laser ablation. |
High-Yield Exam Pearl:
- HPV Strains: Condyloma acuminata are caused by low-risk HPV types (6, 11). High-risk HPV types (16, 18) are strongly associated with squamous cell carcinoma of the cervix, anus, and oropharynx.
- Diagnosis: Usually clinical. Biopsy is only indicated if the diagnosis is uncertain, the lesion is pigmented, atypical, fixed to underlying tissue, or fails to respond to standard therapy.
