Understanding Verrucous Carcinoma: Symptoms, Causes and Treatment

The dermatologist examines the thick, white patch in your mouth that's been there for months. It looks warty, cauliflower-like. She mentions needing a biopsy.

Days later, the report arrives: verrucous carcinoma. The word "carcinoma" confirms your fears - it's cancer. But what kind? How aggressive?

What is verrucous carcinoma?

Verrucous carcinoma meaning comes from its appearance: "verrucous" means wart-like, referring to the characteristic thick, warty growth pattern resembling cauliflower.

The growth invades locally - destroying nearby tissue through pressure and expansion - but rarely enters blood vessels or lymph nodes. This makes it less dangerous than many cancers, though still requiring treatment.

Types of verrucous carcinoma

The different types are classified by location, each with distinct characteristics.

Oral verrucous carcinoma

The most common type accounting for 50-60% of cases. Develops on gums, tongue, cheeks, or floor of mouth as thick, white, warty patches.

This type is strongly linked to tobacco chewing, particularly smokeless tobacco, pan, and betel quid use, which is common in India.

Plantar verrucous carcinoma

Also known as epithelioma cuniculatum, this type typically develops on the sole of the foot. Often misdiagnosed as a wart or corn. Grows deeper into the foot tissues, causing pain when walking.

Genital verrucous carcinoma

Known as Buschke-Löwenstein tumour when large. Develops on the penis, vulva, or perianal area. Associated with HPV infection. Grows as large, cauliflower-like masses.

Other rare types of verrucous carcinoma

Verrucous carcinoma occasionally develops in the nasal cavity, larynx (voice box), oesophagus, or anus. The different types in these locations present unique diagnostic and treatment challenges.

Recognising verrucous carcinoma symptoms early

The verrucous carcinoma symptoms vary by location but share common features:

• •Thick, white or greyish warty growth
  Raised, rough-textured lesion with cauliflower-like appearance
• •Slow, painless growth
  Develops over months to years without pain initially
• •Non-healing sore
  Area that doesn't heal despite treatment
• •Bleeding with minor trauma
  May bleed when brushed or touched
• •Difficulty with function
  Chewing problems (oral), walking pain (plantar), or sexual dysfunction (genital)
• •Local tissue destruction
  Invades surrounding bone, muscle, or other structures

What are verrucous carcinoma causes and risk factors

Chronic irritation drives development. Verrucous carcinoma causes centre on repeated cellular stress rather than single genetic mutations.

What causes verrucous carcinoma?

Normal squamous cells undergo malignant transformation yet retain differentiation - still looking relatively normal. Verrucous carcinoma exhibits this well-differentiated nature, explaining its slow growth and minimal metastasis.

Lifestyle and environmental risk factors

• •Tobacco use
  Smokeless tobacco (gutka, pan masala, betel quid) carries the highest risk for oral type.
• •Alcohol consumption
  Heavy drinking, especially with tobacco, increases oral risk.
• •Poor oral hygiene
  Neglected dental care, ill-fitting dentures, and chronic infections contribute to irritation.
• •Chronic irritation
  Repeated trauma from sharp teeth, dental appliances, or poorly fitting shoes.
• •HPV infection
  Genital type associates with HPV types 6 and 11.

Role of chronic irritation and HPV

Chronic irritation appears central to verrucous carcinoma development. Years of repeated injury and inflammation create cellular stress, promoting cancerous changes.

What is verrucous carcinoma staging

Verrucous carcinoma staging differs from standard cancer staging because this tumour rarely metastasises.

Early-stage verrucous carcinoma

Confined to surface tissue or just invading the underlying connective tissue. Moreover, the size is typically under 2cm. There is no lymph node involvement.

Locally advanced verrucous carcinoma

Tumour exceeds 2cm, invades deeper structures (muscle, bone), but still no distant spread. It may involve nearby lymph nodes, though rare. Treatment becomes more complex.

True metastatic disease remains extremely rare. When spread occurs, it usually indicates transformation to conventional squamous cell carcinoma.

Diagnosis of verrucous carcinoma

How verrucous carcinoma is diagnosed

Verrucous carcinoma diagnosis begins with clinical examination, but definitive diagnosis requires tissue analysis.

Tests used to confirm verrucous carcinoma

• •Incisional biopsy
  Removing tissue for microscopic examination. Must include both surface and depth to assess invasion. Superficial biopsies may miss the diagnosis.
• •Excisional biopsy
  Removing the entire small lesion for diagnosis and treatment simultaneously.
• •Imaging studies
  CT or MRI scans assess invasion into bone or deep structures.
• •HPV testing
  For genital lesions, it confirms HPV involvement.

Treatment approaches for verrucous carcinoma

Verrucous carcinoma treatment focuses on complete surgical removal as first-line therapy.

Surgery for verrucous carcinoma

Surgical excision remains the gold standard. Verrucous carcinoma cure depends on achieving clear margins.

• •Wide local excision
  Removing the tumour plus a 0.5-1cm margin ensures complete removal. Frozen section analysis during surgery confirms clear margins.
• •Mohs micrographic surgery
  Layer-by-layer removal with immediate microscopic examination. Maximises tissue preservation. Useful for facial or genital lesions.
• •Reconstructive surgery
  Large defects may require skin grafts or flaps to restore function and appearance.

Radiation therapy

Radiation therapy has a controversial role. Traditional teaching warns against radiation because some studies have suggested it might cause transformation to a more aggressive cancer. Modern evidence is mixed.

Role of chemotherapy and other treatments

Key takeaways

Stop googling and start acting. If you've noticed persistent warty growths, non-healing patches, or any symptoms described above, book an appointment with a specialist immediately. Waiting never improves outcomes with cancer.
