Introduction

Oral Verrucous Carcinoma (OVC) is a distinctive lesion initially characterized by Ackerman, recognized for its slow growth, local invasiveness, and rarity of metastasis even in advanced stages. It presents with a clinical behavior that reflects aspects of both benign verrucous lesions and oral squamous cell carcinoma (SCC). The study aimed to examine the clinical distribution of OVC and Hybrid Verrucous Carcinoma (HVC) in Chhattisgarh over the past decade, assessing their correlation with patient habits, the duration of those habits, and histopathological parameters such as dysplasia and HPV infection indicators.

Histological Variants and Their Implications

A significant finding from the retrospective analysis revealed that nearly half of the lesions identified were histologically categorized as Hybrid Verrucous Carcinoma. In both OVC and HVC, HPV infection-related changes were noted, indicating a possible relationship with the morphology of the lesions. Importantly, the presence of HPV was highlighted as a potential contributing factor, although it was suggested that its role might not be decisive in distinguishing between the two histological variants. The differentiation of HVC from OVC is crucial due to their varying prognoses, with HVC typically presenting a more aggressive and invasive nature.

Clinical Distribution and Patient Habits

The study highlighted that males were predominantly affected by OVC, particularly those aged above 40 years, and the most common habit linked to the carcinoma was tobacco chewing. Additional habits included a combination of smoking, alcohol use, and poor oral hygiene, with varying distributions across genders. The clinical findings showed a higher incidence of lesions in the posterior buccal mucosa and adjacent areas, stressing the importance of habit history in understanding the development and distribution of OVC and HVC among patients.

Histopathological Evaluation and HPV Infection

Histopathological assessment demonstrated that the majority of lesions exhibited moderate to severe dysplastic changes regardless of the histological type. HPV-related changes, specifically pyknotic nuclei and perinuclear halos, were more prevalent in patients with HVC, suggesting a stronger association between HPV infection and the more aggressive hybrid variant. The presence of significant inflammatory responses in the stroma was noted, indicating that HPV infection not only plays a role in epithelial alterations but may also influence the inflammatory environment within the tumor microenvironment.

Conclusion

This retrospective analysis underscores the necessity for thorough clinical and histological evaluations when assessing Verrucous carcinoma variants. Given the complexities involved in differentiating between OVC and HVC, along with their distinct behaviors and prognoses, accurate diagnostic practices are vital for effective treatment planning. The study emphasizes that understanding the interplay between histological characteristics, clinical presentation, and patient habits is crucial for improving patient outcomes in cases of oral verrucous carcinoma.

FAQ section (important questions/answers):

What is Oral Verrucous Carcinoma (OVC) and its characteristics?

Oral Verrucous Carcinoma (OVC) is a slow-growing lesion characterized by invasive nature, minimal metastases, and clinical behaviors reminiscent of both benign and malignant lesions, making accurate diagnosis important for treatment planning.

What is the relationship between HPV and Verrucous Carcinoma?

Human Papillomavirus (HPV) has been implicated in OVC's etiology, with HPV subtypes 16 and 18 found in up to 40% of cases, suggesting its potential role in altered epithelial morphology and increased dysplasia.

How common is Oral Verrucous Carcinoma among oral cancers?

OVC accounts for 2% to 12% of all oral cancers, with a low 5-year survival rate of approximately 50%, indicating its significance among oral carcinomas.

What habits are associated with developing Oral Verrucous Carcinoma?

Commonly associated habits include tobacco use, smokeless tobacco, and less frequently, alcohol consumption. These habits correlate strongly with the occurrence of OVC in affected individuals.

How does Hybrid Verrucous Carcinoma differ from Oral Verrucous Carcinoma?

Hybrid Verrucous Carcinoma contains foci of OVC and poorly differentiated squamous cell carcinoma (SCC), leading to a more aggressive behavior and difference in prognosis compared to OVC.

What are the common sites for Oral Verrucous Carcinoma lesions?

Lesions typically appear in the posterior buccal mucosa, lower anterior alveolus, and the corners of the lips, with a notable tendency for right-sided oral cavity involvement.
