Background Podoplanin is a type I transmembrane sialomucin-like glycoprotein that is specifically expressed in lymphatic endothelial cells. Studies have shown that assessment of podoplanin expression in the epithelial cells can be used to predict the malignant transformation of potentially malignant disorders and the metastatic tendency of primary head and neck squamous cell carcinoma. The aim ...

Although leukoplakia is the most common precancerous lesion of the oral cavity, its molecular biological properties are largely unknown. The aim of this study was to identify the genes responsible for its pathogenesis and malignant transformation using oligonucleotide microarray technology. The expression profiles of 8,800 genes in human oral leukoplakia (n=4) and oral squamous cell carcinoma (...

BACKGROUND Leukoplakia is an asymptomatic and potentially malignant change in the oral mucosa and high frequencies have been reported among smokers. The present study concerned the prevalence of tobacco use and leukoplakia and also associations between the two. STUDY DESIGN This cross sectional survey was conducted amongst the Gond tribal population of Kundam Block, Jabalpur district, Madhya ...

Oral squamous cell carcinomas develop in precancerous fields consisting of genetically altered mucosal epithelial cells. These precancerous fields may appear as clinically visible lesions, in particular, oral leukoplakia, but the large majority remains clinically undetectable. The aim of this study was to assess the potential value of a noninvasive screening approach to detect precancerous fiel...

Leukoplakia is the most common potentially malignant disorder of the oral mucosa. The frequency of dysplastic or malignant change varies from 15.6-39.2% in different studies. The risk of developing malignancy at the lesional site is 5 times greater in patients with leukoplakia than in patients without them. Hence, it is necessary for early diagnosis of both leukoplakia and Oral squamous cell ca...

BACKGROUND Leukoplakia, is a precancerous lesion that is most commonly encountered in the oral cavity. The grade of dysplasia is presumed to be the most important indicator of malignant potential. There are many promising aspects in advanced methods for the evaluation of oral precancer and cancer. Among these methods, electron microscopic examination predicts the true biologic potential more ac...

UNLABELLED Mast cell contribution to neoangiogenesis during tumorigenesis in oral squamous cell carcinoma is not determined yet. OBJECTIVES To associate numerical mast cell density (MCD) to numerical microvessel density (MVD) during the progression of oral leukoplakia without dysplasia and leukoplakia with dysplasia to squamous cell carcinoma (OSCC). MATERIALS AND METHODS MVD was analysed i...

Oral leukoplakia presents as a white patch on the oral mucosa and is recognized as having significant malignant potential. Although colonization of these patches with Candida albicans is common, little is known about the bacterial microbiota of these patches. In the current study we analyzed the microbiome of oral leukoplakia in 36 patients compared to healthy mucosal tissue from the same patie...

Silver binding nucleolar organizer regions (AgNOR) in normal oral mucosa (NOM), oral leukoplakia with epithelial dysplasia (ED), and oral squamous cell carcinoma (OSCC) were studied. The mean AgNOR count per nucleus increased from NOM to ED to OSCC. Tissue showing ED in oral leukoplakia and OSCC cases showed higher counts, wider scatter, and smaller size of AgNOR dots in the nuclei. The study s...

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...
