SOX2 Expression Is an Independent Predictor of Oral Cancer Progression.

Potentially malignant oral lesions, mainly leukoplakia, are common. Malignant transformation varies widely, even in the absence of histological features such as dysplasia. Hence, there is a need for novel biomarker-based systems to more accurately predict the risk of cancer progression.

The Emerging Role of NANOG as an Early Cancer Risk Biomarker in Patients with Oral Potentially Malignant Disorders.

NANOG, a key regulator of pluripotency and self-renewal in embryonic and adult stem cells, is frequently overexpressed in multiple cancers, including oral squamous cell carcinoma (OSCC). It has been frequently associated with poor outcomes in epithelial cancers, and recently implicated in laryngeal tumorigenesis. On this basis, we investigated the role of NANOG protein expression as an early cancer risk biomarker in oral potentially malignant disorders (OPMD), and the impact on prognosis and disease outcomes in OSCC patients.

Keratocyst Capnocytophaga superinfection.

Introduction: Capnocytophaga spp are Gram-negative bacteria that cause severe infections in immunosuppressed patients. This situation is extremely rare in immunocompetent patients.

Case Report: This clinical report describes the unusual infection of an immunocompetent patient with Capnocytophaga spp.
