Erythematous lesions of the oral mucosa are common and can reflect a variety of conditions, ranging from benign reactive or immunologically-mediated disorders to malignant disease. Together with vascular abnormalities, which can vary from reddish to bluish-purple in color, the differential diagnosis for erythematous oral mucosal change is quite diverse. This review focuses on salient clinical features and histopathologic findings of selected conditions which clinically present as red or vascular-like oral mucosal alterations, including oral vascular malformations and neoplasms, pyogenic granuloma, localized juvenile spongiotic gingival hyperplasia, denture stomatitis, benign migratory glossitis (geographic tongue), orofacial granulomatosis, granulomatosis with polyangiitis (Wegener granulomatosis), megaloblastic anemia, and erythroplakia.

Oral carcinoma (OC) is the major cancer type in the head and neck region; however, the molecular mechanisms of its pathogenesis and progression remain poorly understood. In recent years, the long noncoding RNAs (lncRNAs) have been uncovered as critical regulators in the development and progression of multiple human cancers, but most of the lncRNAs expression patterns, clinical relevance, and biological functions in OC are still unclear. To better understand the significance of lncRNAs in OC carcinogenesis, we analyzed the expression levels of lncRNAs between OC and healthy oral mucosa using The Cancer Genome Atlas Cancer Genome RNA sequencing data and another three independent microarray datasets from Gene Expression Omnibus.

Background: About 74% of head and neck cancer (HNC) patients need to undergo either definitive or postoperative radiation therapy because of aggressive nature of disease. The transition from two-dimensional conventional radiotherapy to three-dimensional conformal radiotherapy (3D-CRT) and further technological evolutions led to the successful clinical implementation of intensity modulated radiation therapy (IMRT), which constitutes an evolution of 3D-CRT. The IMRT technique gives the ability to create treatment fields with varying beam intensity using inverse planning and optimization algorithms to treat irregularly shaped target volumes with high precision.

Background: To develop an individually-tailored dynamic risk assessment model following a multistep, multifactorial process of the Correa's gastric cancer model.

Methods: First, we estimated the state-to-state transition rates following Correa's five-step carcinogenic model and assessed the effect of risk factors, including Helicobacter pylori infection, history of upper gastrointestinal disease, lifestyle, and dietary habits, on the step-by-step transition rates using data from a high-risk population in Matsu Islands, Taiwan. Second, we incorporated information on the gastric cancer carcinogenesis affected by genomic risk factors (including inherited susceptibility and irreversible genomic changes) based on literature to generate a genetic and epigenetic risk assessment model by using a simulated cohort identical to the Matsu population.
