Oral Squamous Cell Carcinoma of the Right Buccal Mucosa: A Case Report.

Oral squamous cell carcinoma (OSCC) is indeed one of the most common types of oral cancer, typically affecting individuals over the age of 50. It primarily originates from the squamous epithelial cells lining the oral cavity. While it is relatively rare in individuals under 40 years old, it can still occur, albeit less frequently in that age group.

Hemangioma of Tongue With Multiple Phleboliths Involving Multiple Spaces of the Right Side of the Head and Neck Region: A Case Report Along With the Importance of Specialized Imaging.

Hemangioma is one of the most common tumors of dilated blood vessels, which is usually present at birth and involutes over time. Although considered the most common tumor in the head and neck region, the oral cavity is less commonly affected. The occurrence of hemangioma in the tongue is very rare (14%).

Revealing the heterogeneity in neuroblastoma cells nanopillar-guided subnuclear deformation.

Neuroblastoma is a hard-to-treat childhood cancer that is well known for the heterogeneity of its clinical phenotypes. Although the risk levels of neuroblastoma have been defined from a complex matrix of clinical and tumor biological factors to guide treatment, the accuracy in predicting cancer relapse and related fatality is still poor in many cases, where heterogeneity with subpopulations in highly malignant or drug-resistant tumors is believed to be underestimated by the current analysis methods. Therefore, new technologies to probe neuroblastoma heterogeneity are needed for the improvement of risk stratification.

The chromatin structuring protein HMGA2 influences human subtelomere stability and cancer chemosensitivity.

The transient build-up of DNA supercoiling during the translocation of replication forks threatens genome stability and is controlled by DNA topoisomerases (TOPs). This crucial process has been exploited with TOP poisons for cancer chemotherapy. However, pinpointing cellular determinants of the best clinical response to TOP poisons still remains enigmatic.

The RNA interactome of human telomerase RNA reveals a coding-independent role for a histone mRNA in telomere homeostasis.

Telomerase RNA (TR) provides the template for DNA repeat synthesis at telomeres and is essential for genome stability in continuously dividing cells. We mapped the RNA interactome of human TR (hTR) and identified a set of non-coding and coding hTR-interacting RNAs, including the histone 1C mRNA (). Disruption of the hTR- RNA association resulted in markedly increased telomere elongation without affecting telomerase enzymatic activity.

Verrucoid Variant of Invasive Squamous Cell Carcinoma in Oral Submucous Fibrosis: A Clinicopathological Challenge.

Verrucous carcinoma (VC) is an exophytic, low-grade, well-differentiated variant of squamous cell carcinoma. It is described as a lesion appearing in the sixth or seventh decade of life that has minimal aggressive potential and, in long-standing cases, has been shown to transform into squamous cell carcinoma. Oral submucous fibrosis (OSMF) is a potentially malignant disorder, and about one-third of the affected population develop oral squamous cell carcinoma.
