background: syndecan‑1 is abundant in normal tissues and reduced in squamous cell carcinomas. leukoplakia and oral submucous fibrosis (osf) are oral pre‑cancerous disorders that have potential for malignant transformation. the aim of this study was to evaluate the expression of syndecan‑1 in leukoplakia and osf and to identify its role as a reliable marker for predicting malignant changes. mate...
background: leukoplakia is a common, potentially premalignant lesion with malignant transformation rate from 1 to 17% with highest transformation rate for the lesions on the floor of the mouth, soft palate and tongue. one of the main etiological factors is consuming areca nut and its commercial preparations which generate high levels of reactive oxygen species during their metabolism. so the ai...
OBJECTIVES to report the immunoexpression of metallothionein in oral leukoplakia and to correlate with histological grade and clinical localization. Leukoplakia is the most common potentially malignant lesion of the oral cavity. As the histological study of oral leukoplakia can not predict precisely the malignant transformation of this lesion, and metallothionein is a protein that has been asso...
BACKGROUND Oral cancer is the 8th most common cancer worldwide. Squamous cell carcinomas constitute 94% of all oral malignancies and are often preceded by leukoplakia. Despite many adjunctive techniques to monitor transformation of leukoplakia to oral squamous cell carcinoma (OSCC), the mortality rate is on the rise. Incidentally, patients diagnosed with oral potentially malignant disorders (OP...
Proliferative verrucous leukoplakia (PVL) is a particularly aggressive form of oral leukoplakia that is resistant to treatment and presents a high risk of recurrence and malignant transformation. This article describes the microscopic and clinical characteristics of one case of PVL, which initially presented as hyperkeratosis with mild dysplasia and posteriorly developed multifocal areas and ve...
