BACKGROUND Oral cancers can be preceded by clinically evident oral potentially malignant disorders (OPMDs). The current study evaluated the rate and the time of malignant transformation in the various OPMDs in a cohort of patients from southern Taiwan. Parameters possibly indicative for malignant transformation of OPMDs, such as epidemiological and etiological factors, and clinical and histopat...

Background: Oral lesions can affect people’s quality of life by interfering with chewing, swallowing, and speech. These may originate from epithelial or mesenchymal tissues. Malignant oral be life-threatening. Epidemiological data in Iran is limited. Objective: This study aims to investigate the frequency Rasht, Iran. Methods: In this cross-sectional study, histopathologic reported Razi laborat...

Oral squamous cell carcinoma is the most common malignant epithelial neoplasm affecting the oral cavity. This article overviews the essential points of oral squamous cell carcinoma, highlighting its risk and genomic factors, the potential malignant disorders and the therapeutic approaches. It also emphasizes the importance of the early diagnosis.

background: imbalances between the oxidant-antioxidant status have been implicated in the pathogenesis of several diseases, including oral cancer. majority of oral cancer are preceded by a well-recognized group of pre-malignant lesions. however, only a small fraction of those lesions, undergo malignant transformation. hence, there is a great need to identify biological markers, which will assis...

primary oral melanoma is a rare neoplasm of melanocytic origin, accounting for 0.5% of all oral malignancies. the “chameleonic” presentation of a mainly asymptomatic condition, rarity of this lesion, poor prognosis, and the necessity of a highly specialized treatment are factors that should be seriously considered by the involved health provider. here is a case report presenting a malignant mel...

Epitheloid hemangioendothelioma (EHE) is an uncommon angiocentric neoplasm of intermediate malignant potential. This tumor is frequently seen in the lungs and liver, but its presentation in the oral cavity is rare. In the oral cavity, gingival region is the common sites of occurrence. We report a rare case of epitheloid hemangioendothelioma in a 48-year-old male, presenting as a growth in the u...

BACKGROUND The diseases that affect the oral cavity are wide and diverse, comprising a broad spectrum of either benign or malignant lesions. However, few histological-based studies were performed for the evaluation of oral cavity lesions, and very few directed to oral soft tissue pathology. The aim of this study was to carry out pioneering research, within a Portuguese population, to determine ...
