Introduction: The present study analyzed the occurrence of exophytic verrucous hyperplasia (EVH) in the background of oral submucous fibrosis (OSF), which presents clinically as a solitary verrucopapillary lesion (VPL) mimicking malignancy. We also aimed to obtain additional information on VELscope appearance and histopathological features of EVH. Materials and Methods: The prevalence of EVH in OSF background was assessed from January 2014 to December 2018 using VELscope and histopathological examination. Results: Six hundred and sixty-two OSF patients were examined. Thirteen patients presented with solitary VPL in OSF background. A VELscope examination found ten cases with increased autofluorescence (fluorescence visualization increase, FVI), two cases with autofluorescence loss (fluorescence visualization loss, FVL), whereas one case exhibited dual autofluorescence (focal areas of FVL within FVI regions). Histopathologic examination revealed two FVL cases as oral verrucous carcinoma (OVC) and oral squamous cell carcinoma (OSCC) and one dual autofluorescence case as OVC, while six FVI cases showed nondysplastic epithelium having verrucopapillary pattern without connective tissue invasion, consistent with the clinicopathological diagnosis of EVH. Conclusion: The present study demonstrated the evidence of EVH in OSF background, which on histopathological examination revealed nondysplastic epithelium exhibiting the verrucopapillary pattern. A VELscope examination of these lesions showed increased autofluorescence, suggesting its nonneoplastic nature of clinically malignant-looking exophytic VPLs in OSF background. Present study suggests newer perspective for using the term oral verrucous hyperplasia (OVH) and EVH with justification and also proposes to introduce new terminology such as oral verrucous dysplasia and exophytic verrucous dysplasia.
