Overview
Verrucous carcinoma is a variant of squamous cell carcinoma characterized by its warty appearance and slow but locally invasive growth pattern, commonly found in the oral cavity. It is often associated with chronic irritation, particularly from tobacco use 1.Diagnosis
Histopathological Examination: Essential for definitive diagnosis, identifying the verrucous pattern and invasive characteristics 1.
Tumor Thickness/Depth of Invasion: Critical for staging; accurate measurement aids in prognosis and treatment planning 1.
Pattern of Invasive Front: Evaluates the extent and aggressiveness of tumor spread 1.
Perineural Invasion: Assessment of nerve involvement is crucial for determining local invasiveness and potential complications 1.
Margin Assessment: Clear margins are vital for surgical planning and outcomes 1.Management
Surgical Excision: Primary treatment, often requiring wide local excision to ensure clear margins 1.
Reconstructive Surgery: Frequently necessary post-excision to restore function and appearance 1.
Adjuvant Radiotherapy: Considered for high-risk features such as deep invasion, lymphovascular invasion, or positive margins to reduce recurrence risk 1.Special Populations
Comorbidities: Management considerations may vary based on patient comorbidities, necessitating individualized treatment plans 1.Key Recommendations
Accurate histopathological evaluation including tumor thickness, invasive pattern, and perineural invasion is essential for staging and guiding treatment decisions (Evidence: Strong 1).
Surgical excision with wide margins is recommended to optimize local control and minimize recurrence (Evidence: Strong 1).
Adjuvant radiotherapy should be considered for patients with high-risk features to improve outcomes (Evidence: Moderate 1).References
