The intriguing molecular pathways involved in oral carcinogenesis are still ambiguous. The oral squamous cell carcinoma (OSCC) ranks as the most common type constituting more than 90% of the globally diagnosed oral cancers cases. The elevation in the OSCC incidence rate during past ten years has an alarming impression on human healthcare. The major challenges associated with OSCC include delayed diagnosis, high metastatic rates, and low five-year survival rates. The present work foundations on reverse genetic strategy and involves the identification of genes showing expressional variability in an OSCC case lacking addictive proclivities for tobacco, betel nut and/or alcohol, major etiologies...

Oral cavity is nidus of much pathology. Some may arise due to altered eating habits such as meat, uncooked food etc. The parasitic infections arising from ingesting uncooked pork (larva of pork tapeworm) called as cysticercosis and being undiagnosed lead to "diagnostic dilemma". Herein we report a case of cysticercosis involving the right dorsum of tongue along with review of literature.

PURPOSE: The objective of the present study was to evaluate the potential application value of diffusion-weighted magnetic resonance imaging (DW-MRI) to differentiate solid benign from malignant tumors affecting the base of tongue and glossopharynx. METHODS: Sixty-one patients who presented with solid tumors affecting the base of tongue and glossopharynx underwent conventional MRI and DW-MRI before pathologic verification. Based on pathologic findings, the tumors were classified into 4 groups: Group 1, solid benign tumor (n=10); Group 2, epithelial carcinoma (n=35); Group 3: non- epithelial malignant tumor (n=16); and Group 4: malignant tumor (n=51, a combination of Group 2 and 3)...

High-grade endometrial stromal sarcoma likely encompasses underrecognized tumors harboring genetic abnormalities besides YWHAE-NUTM2 fusion. Triggered by three initial endometrial stromal sarcomas with ZC3H7B-BCOR fusion characterized by high-grade morphology and aggressive clinical behavior, we herein investigate the clinicopathologic features of this genetic subset by expanding the analysis to 17 such tumors. All of them occurred in adult women with a median age of 54 (range, 28-71) years. They were predominantly based in the endomyometrium and demonstrated tongue-like and/or pushing myometrial invasion...

Chorea-acanthocytosis (ChAc), a neurodegenerative disease, results from loss-of-function-mutations of the chorein-encoding gene VPS13A. Affected patients suffer from a progressive movement disorder including chorea, parkinsonism, dystonia, tongue protrusion, dysarthria, dysphagia, tongue and lip biting, gait impairment, progressive distal muscle wasting, weakness, epileptic seizures, cognitive impairment, and behavioral changes. Those pathologies may be paralleled by erythrocyte acanthocytosis. Chorein supports activation of phosphoinositide-3-kinase (PI3K)-p85-subunit with subsequent up-regulation of ras-related C3 botulinum toxin substrate 1 (Rac1) activity, p21 protein-activated kinase 1 (PAK1) phosphorylation, and activation of several tyrosine kinases...

The current standard of care in oral tongue cancer surgery is complete resection with a target of 5-mm microscopic clearance at all margins on final pathologic review. While current methods of resection are often successful at determining the mucosal margins of the lesion, they may be limited when attempting to achieve an adequate deep margin. A number of previous studies suggested that ultrasound is superior to manual palpation and other imaging modalities (computed tomography, magnetic resonance imaging) at demarcating the margins of tongue lesions...

BACKGROUND: Renal cell carcinoma is the third most common tumor that metastasizes to the head and neck, after breast and lung carcinomas. Tongue metastasis as an initial presentation of renal cell carcinoma is extremely rare, and very few cases have been reported. The prognosis is poor. We present a rare case of metastatic renal cell carcinoma that initially presented as a tongue lesion. CASE PRESENTATION: We report the case of a 55-year-old white man who presented with a large exophytic lesion on his tongue...

Parkinson disease (PD) is devastating to sensorimotor function that includes cranial/oromotor and limb motor deficits. However, the onset, progression, and neural correlates of PD-related dysfunctions are poorly understood. To address this gap, we used a genetic rat model of PD, DJ1 -/-, and hypothesized that motor deficits would manifest early in the disease process, be progressive in nature, and be related to pathologies in brainstem structures associated with sensorimotor function. The present study compares homozygous DJ1 -/- male rats to age-matched wild type controls...

Rationale Desorption electrospray ionization-mass spectrometry (DESI-MS) has demonstrated utility in differentiating tumor from adjacent normal tissue in both urologic and neurosurgical specimens. We sought to evaluate if this technique had similar accuracy in differentiating oral tongue squamous cell carcinoma (SCC) from adjacent normal epithelium due to current issues with late diagnosis of SCC in advanced stages. METHODS: Fresh frozen samples of SCC and adjacent normal tissue were obtained by surgical resection...

Clear cell carcinoma (CCC) is a low-grade malignancy that commonly arises in minor salivary glands of the oropharynx and other sites. EWSR1-ATF1 gene fusions seem to be specific for this salivary neoplasm. Testing for EWSR1-ATF1 has expanded the histologic spectrum of CCC. As one important example, many CCCs have a predominantly squamous phenotype with few clear cells, a finding that can cause confusion with squamous cell carcinoma (SqCC). P16 immunohistochemical staining to determine human papillomavirus (HPV) status has become standard practice for all oropharyngeal carcinomas showing squamous differentiation...

BACKGROUND: Orofacial granulomatosis is a relatively recent term coined by Wiesenfield et al. in 1985 to define granulomatous lesions of oral mucosa without intestinal involvement. When it presents in a triad encompassing facial nerve palsy, lip swelling, and fissured or furrowed tongue it is called Melkersson-Rosenthal syndrome while monosymptomatic or oligosymptomatic forms are referred to as granulomatous cheilitis. It is an uncommon clinicopathologic entity which is distinct from classic Crohn's disease...

We report the development of optical coherence tomography- (OCT) based angiography (OCTA) to image blood flow within microcirculatory tissue beds in human oral cavity in vivo with a field of view at 10 mm × 10 mm. Three-dimensional (3D) structural and vascular images of labial mucosa tissue are obtained at a single 3D acquisition. Pathologic mucosal sites with mouth ulcers are examined using the OCT tomograms and angiograms, upon which to monitor the lesion healing process over a period of 2 weeks. Quantitative metrics of the capillary loop density within the lamina propria layer are evaluated, providing statistically significant difference between healthy and diseased conditions over time...

The updated eighth edition of the Cancer Staging Manual of the American Joint Committee on Cancer will be implemented in January 2018. There are multiple changes to the head and neck section of the manual, which will be relevant to radiologists participating in multidisciplinary head and neck tumor boards and reading pretreatment head and neck cancer scans. Human papillomavirus-related/p16(+) oropharyngeal squamous cell carcinoma will now be staged separately; this change reflects the markedly better prognosis of these tumors compared with non-human papillomavirus/p16(-) oropharyngeal squamous cell carcinoma...

AIMS: To develop a tongue pain model with no mucosal pathologic changes and to examine whether phosphorylation of p38 in trigeminal ganglion (TG) neurons innervating the tongue is associated with tongue heat hypersensitivity in mice. METHODS: Tongue heat sensitivity in mice was assessed following application of the irritant 2,4,6-trinitrobenzene sulfonic acid (TNBS) to the tongue. After TNBS application, the expressions of p38, phosphorylated p38 (pp38), and transient receptor potential vanilloid 1 (TRPV1) were examined in TG neurons innervating the tongue...

Aim: The research described is intended to give a description of articulation dynamics as a correlate of the kinematic behavior of the jaw-tongue biomechanical system, encoded as a probability distribution of an absolute joint velocity. This distribution may be used in detecting and grading speech from patients affected by neurodegenerative illnesses, as Parkinson Disease. Hypothesis: The work hypothesis is that the probability density function of the absolute joint velocity includes information on the stability of phonation when applied to sustained vowels, as well as on fluency if applied to connected speech...
