oral malignant melanoma (omm) accounts for 5% of all oral malignancies. it is a rare aggressive neoplasm usually found on the hard palate and gingiva. the etiology is unknown, but tobacco and chronic irritation are suggested as probable causative factors. over 30% of the cases have been reported to arise from pre-existing pigmented lesions. a biopsy is required to establish the diagnosis and th...

Background: This study also will help to identify the specific site of biopsy of oral pre-malignant and malignant lesions and to correlate lugol’s iodine solution staining of oral tissue with histological findings. Objective: The aim of this study to detect any suspicious of oral cancerous and pre-cancerous lesions as an early diagnostic tool. Methods: Sixty cases of oral lesions were selected ...

BACKGROUND Oral malignant tumors in Thailand have not been extensively studied. Hence the following study was conducted. AIMS To determine the prevalence and clinicopathologic data of the oral malignant tumors from Thailand. SUBJECTS AND METHODS Biopsy records of the Oral Pathology Department, Chulalongkorn University; Department of Oral Biology and Diagnostic Sciences, Chiang Mai Universit...

Objective. To assess the prevalence of oral potentially malignant disorders and to determine the potential risk factors for its development in Indian population. Materials and Methods. This cross-sectional study was carried out on 1241 individuals in Indore, Madhya Pradesh. A questionnaire was designed to record information about sociodemographic characteristics, oral hygiene practices, dietary...

Background and Aim: Oral lichen planus (OLP) is a chronic mucocutaneous disease, which is considered a precancerous condition. OLP is a multifactorial disease with no conclusive treatment. Timely diagnosis and treatment of oral lesions are necessary steps to prevent malignant transformations and severe complications of oral cancer. This study aimed to evaluate the frequency and severity of mali...

Sarawak's economic sector relies on tourism as a stimulant. This research evaluated the potential of new tourist destination in Sarawak, particularly region involved construction Pan-Borneo highway. The was carried out pioneering focus at Kampung Telok Melano, Sematan, which is starting point for highway project southwest. selection Melano study's location notable since this has been featured p...

The knowledge of cell-cycle control has shown that the capacity of malignant growth is acquired by the stepwise accumulation of defects in specific genes regulating cell growth. Histologic diagnosis might be improved by a quantitative evaluation of more specific diagnosis biomarkers, which could help to precisely identify pre-malignant and malignant oral lesions. The aim of the present study is...

Oral lichen planus (OLP) is a chronic inflammatory disease of the oral mucosa which is considered by the World Health Organization (WHO) as a premalignant condition. One step in malignant development is so called epithelial mesenchymal transition (EMT), a process whereby epithelial cells acquire mesenchymal characteristics. A factor known to induce EMT is the transforming growth factor-β (TGF-β...

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...
