HPV is a highly common group of viruses, and most people contract a strain at some point. While many HPV infections are asymptomatic, some strains cause epithelial growths, or warts, on various parts of the body. When the infection manifests in the mouth, it is known as oral HPV. The resulting lesions can appear on the lips, throat, or most notably, the tongue. These tongue lesions are typically benign physical manifestations of the virus.
Physical Characteristics of Oral HPV Lesions
Oral HPV lesions on the tongue often present as small, hard, raised bumps. These growths are commonly referred to as warts, though they are medically classified as oral squamous papillomas or condyloma acuminata. A defining characteristic is their typically painless nature, meaning they often go unnoticed until they reach a noticeable size or location.
The texture of the bumps is frequently described as exophytic, meaning they grow outward from the surface tissue. They often display a distinct finger-like projection pattern, giving them a rough, cauliflower-like, or warty surface texture. In other cases, the growth may have a smoother, more pebbly appearance.
The color of these lesions usually blends with the surrounding oral tissue, appearing flesh-toned, pale pink, or white. The white appearance is a result of keratin buildup on the lesion’s surface due to constant friction inside the mouth. Most lesions are small, typically measuring less than one centimeter in diameter, and can be solitary or appear as multiple growths clustered together.
The bumps may be attached to the tongue surface either by a broad base, known as sessile, or by a narrow stalk, which is called pedunculated. They can appear on the dorsal surface, the sides, or even the base of the tongue near the throat. The location and size can influence whether they cause symptoms, such as a feeling of fullness or difficulty swallowing.
Distinguishing HPV Bumps From Other Tongue Irregularities
Identifying an HPV lesion can be difficult because the tongue naturally contains numerous structures and is prone to other common, benign irritations. One frequent confusion is mistaking normal fungiform papillae for abnormal growths. These healthy, mushroom-shaped taste buds are typically smooth and slightly redder than the surrounding tissue, unlike the distinctively rough or warty texture of an HPV lesion.
Canker sores, or aphthous ulcers, are another common irregularity that is visually and symptomatically different from HPV bumps. Canker sores are characterized by a painful, crater-like appearance with a central white or yellowish depression surrounded by a red, inflamed border. In contrast, HPV lesions are raised, firm growths that are usually painless and do not present as an open, ulcerated wound.
Bumps caused by trauma, such as accidental biting or injury from sharp foods, are usually tender or painful and resolve on their own within a short period. This temporary nature distinguishes them from HPV-related growths. HPV lesions are persistent and can last for weeks, months, or even years without intervention.
Diagnosis and Management
Self-diagnosis of any oral lesion is unreliable, so any persistent or unusual bump should be evaluated by a healthcare provider, such as a dentist or physician. A professional examination is necessary to definitively determine the nature of the growth. The diagnostic process typically begins with a thorough visual and physical examination of the mouth and throat. If the lesion is suspicious, a biopsy is often performed, which involves taking a small tissue sample for laboratory analysis. This procedure confirms the presence of HPV and determines the specific type of lesion.
Many oral HPV infections are transient and may be cleared by the body’s immune system without treatment over one to two years. However, lesions that cause discomfort, interfere with speech or swallowing, or are cosmetically concerning are often removed. Treatment options focus on lesion removal and include surgical excision, cryotherapy (freezing), or laser therapy. Removal is also recommended to allow for a definitive tissue diagnosis and to prevent the potential spread of the wart to other areas.
