Management of HPV-Associated Oral Lesions
Diagnosis and Treatment
- The American Academy of Otolaryngology-Head and Neck Surgery recommends surgical excision as the treatment for HPV-related oral lesions, including squamous papilloma, condyloma acuminatum, verruca vulgaris, and multifocal epithelial hyperplasia, due to the risk of dysplasia and malignancy, particularly in immunosuppressed patients 1, 2
- Squamous papilloma is the most common HPV-associated oral lesion, accounting for approximately 94% of cases, and is caused by low-risk HPV types 6 and 11 in about 50% of cases 2
- Condyloma acuminatum is caused by low-risk HPV 6 and 11, but may also harbor high-risk types 16 and 18, increasing the risk of dysplasia and squamous cell carcinoma development, particularly in immunosuppressed individuals 1, 3
- Verruca vulgaris is a well-circumscribed growth caused by HPV 2 and 4, and occurs via autoinoculation from fingers to mouth 2, 4
- Multifocal epithelial hyperplasia is a rare condition caused by HPV 13 and 32, characterized by multiple small papules, and often spontaneously regresses after months to years 2, 4
Treatment Algorithm
- Complete surgical excision is the standard of care for HPV-associated oral lesions, as it prevents recurrence and reduces the risk of dysplasia and malignancy 1, 2
- Alternative treatment options for condyloma acuminatum include cryotherapy, electrocautery, topical agents, and photodynamic therapy, which have varying degrees of effectiveness and recurrence rates 3
Critical Management Considerations
- High-risk HPV genotypes, such as 16 and 18, are associated with an increased risk of dysplasia and squamous cell carcinoma, particularly in immunosuppressed patients and those with lesions showing progressive growth or ulceration 1, 4
- Regular monitoring is essential, particularly for immunosuppressed patients, those with lesions showing persistent growth or change in appearance, and patients with condylomata harboring high-risk HPV types 1, 4
