Proliferative Verrucous Leukoplakia Revisited: A Retrospective Clinicopathological Study.

(1) Objective: To review the criteria proposed by Cerero-Lapiedra et al. and to retrospectively identify the under-diagnosed disease in patients diagnosed with proliferative verrucous leukoplakia. (2) Materials and methods: In this study, we included patients who were diagnosed with leukoplakia (histological label consistent with the clinical diagnosis, = 95), and cases with a final diagnosis within the spectrum of proliferative verrucous leukoplakia ( = 110) as defined by Batsakis et al.

Expression of Ki-67, p53, α-SMA and COX-2 in lichen planus and related lesions: A pilot study.

Background: Researchers have struggled to understand the natural history of lesions presenting with both lichenoid features and epithelial dysplasia. Thus the present study was designed to differentiate between OLP, OLP with dysplasia, epithelial dysplasia and epithelial dysplasia with lichenoid features based on the expressions of ki-67, p53, COX-2, and α-SMA.

Materials And Methods: Formalin-fixed paraffin-embedded archival specimens of OLP, OLP with dysplasia, epithelial dysplasia and epithelial dysplasia with lichenoid features were subjected to immunohistochemical staining with ki-67, p53, COX-2, and α-SMA.

Oral Candidal Carriage in Subjects with Pure Vegetarian and Mixed Dietary Habits.

Introduction: being a part of the normal oral microbial flora is one of the most commonly isolated species from the oral cavity. Recent studies have shown a steady rise in the number of non species, which are relatively resistant to common antifungal agents and are being recognized as potential pathogens. It is vital to ascertain the predisposing factors leading to such a shift in the oral candidal flora.

Issues related to diagnosing oral lichen planus among oral pathologists in South India: A pilot survey.

Aim: In the present study, we simulated clinical scenarios by explicitly describing the history and clinical and histological features of hypothetical patients presenting with oral lichen planus (OLP), oral lichenoid lesion, and epithelial dysplasia in a self-designed questionnaire. By doing so, we aimed to elicit a diagnosis from oral pathologists and trainees, analyze their responses, appraise issues, and propose solutions regarding the diagnosis of OLP.

Methods: The questionnaire was distributed to 100 oral pathologists and trainees in South India.

Exophytic oral verrucous hyperplasia: a new entity.

Objective: Exophytic oral verrucous hyperplasia (OVH) is a new entity described by an expert working group from South Asia. First reported in Taiwan, there are no reports so far from an Indian population. The aim was to use the microscopic features described by the expert group to differentiate OVH from other oral verruco-papillary lesions in an Indian archive.
