Hypoglossal nerve palsy (HNP) is a common finding in neurologic diseases when associated with other cranial nerve palsies or further pathology and exhibits characteristic clinical manifestations, including unilateral atrophy of the musculature of the tongue. It occasionally appears as the initial or solitary sign of an intracranial or extracranial space-occupying lesion, head or neck injury, or vascular abnormality of the internal carotid artery. There are few cases of idiopathic isolated unilateral HNP, which should be diagnosed through exclusion...

OBJECTIVE: For many years, the microsurgical transoral approach (TOA) has been accepted as the "gold standard" for the surgical treatment of a variety of congenital, developmental, and acquired pathologies affecting the craniovertebral junction. In the present study, we try to investigate both experimental and clinical fronts of such a challenging surgery, starting from the updated literature experience. TOA is actually presented as an "old-fashioned" surgical technique dealing with possible bacterial contamination, the need of postoperative nose gastric tube feeding for a week, the possible nasopharyngeal incompetence, and the postoperative tongue swelling...

AIMS: Oral tongue squamous cell carcinoma (OTSCC) has a relatively poor outcome and there is a need to identify better prognostic factors. Recently, tumour-stroma ratio (TSR) has been associated with prognosis in several cancers. This multi-institutional study evaluates the prognostic value of TSR from original HE-stained tumor-resection slides in a series of early-stage (cT1-2N0) OTSCC patients. METHODS AND RESULTS: A TSR cutoff value of 50% was used to divide the patients into stroma-rich (≥50%) and stroma-poor (<50%) groups...

Background: Oral peripheral nerve sheath tumors (OPNSTs) are reactive or neoplastic diseases that develop from proliferation of the nerve itself or their limiting sheaths. Here we describe the clinicopathologic data of OPNSTs observed in a sample of the Brazilian population and evaluate the expression of molecules associated with neural biology to determine their usefulness in the diagnosis. Material and Methods: Descriptive study of cases diagnosed as OPNSTs, from the Pathology Laboratory at the School of Dentistry/ Federal University of Uberlandia, followed by an immunohistochemical study of S-100, CD57, neurofilament protein (NFP) and epithelial membrane antigen (EMA)...

F-FDG PET/CT and MRI were performed in a 44-year-old woman to characterize a mass of the anterior tongue. MR images showed a voluminous mass, well circumscribed and enhanced heterogeneously after gadolinium chelates injection. There was an intense uptake on PET/CT. Pathological examination and molecular analysis revealed the diagnosis of clear cell sarcoma of the tongue. We present a case of clear cell sarcoma of the tongue, which includes imaging features. It is an extremely rare tumor, with only 3 cases previously reported in the literature...

Osseous choristomas are rare benign lesions characterized by ectopic bone formation in the soft tissue of the head and neck region. Dermoscopy visualizes the morphological characteristics that are not observable by the naked eye, and may be used for the evaluation of calcification under the skin. The present study reports a case of an osseous choristoma arising in the tongue, and reveals the dermoscopic features of osseous choristoma from a surgical specimen. A 7-year-old boy was referred to the Department of Dentistry and Oral Surgery, with an asymptomatic pedunculated mass in the tongue...

Surgery is the mainstay of treatment for low-stage (stage I/II, ie, T1N0/T2N0) squamous cell carcinoma of oral cavity. However, a significant percentage of low-stage squamous cell carcinoma of oral cavity will develop local recurrence and disease-related mortality. In this study, we stratified 64 patients with low-stage of oral tongue and floor of mouth patients into high-, intermediate- and low-risk categories based on existing histologic risk model. The classification of these risk categories was based on presence or absence of perineural invasion and evaluation of tumor-host junction for worst pattern of invasion and lymphocytic host response...

C-reactive protein (CRP) acts as a biomarker reflecting different degrees of inflammation. Accumulating reports have suggested that there is a close relationship between CRP and various cancers. However, the influence of CRP on the development of tongue squamous cell carcinoma (TSCC) remains unclear. The purpose of this study was to investigate the role of CRP in TSCC. The results of immunohistochemical staining and statistical analyses showed that CRP expression was associated with TSCC tumor size, lymph node metastasis and pathological differentiation...

Collet-Sicard syndrome is a rare syndrome that involves paralysis of 9th to 12th cranial nerves. We report an uncommon case of schwannoma of the hypoglossal nerve in a 39-year-old woman presented with slurred speech, hoarse voice, and swallowing difficulty. Physical examination revealed decreased gag reflex on the right side, decreased laryngeal elevation, tongue deviation to the right side, and weakness of right trapezius muscle. MRI revealed a mass lesion in the right parapharyngeal space below the jugular foramen...

BACKGROUND AND IMPORTANCE: A direct transcondylar approach to treat symptomatic arachnoid cysts of the hypoglossal canal has not yet been described in the literature. CLINICAL PRESENTATION: Here, we present a skull base approach in 2 female patients (68 and 38 yr) with progressive dysphagia, dysarthria, half-sided weakness, and atrophy of the tongue due to an arachnoid cyst of the hypoglossal canal. After patient informed consent, both patients were successfully operated on without complications using a transcondylar approach, and their symptoms improved 3 mo after surgery; in both patients, resection of the cyst was confirmed using magnetic resonance imaging...

Oral mucositis is still one of the most painful side effects of chemotherapeutic treatment and a mounting body of evidence suggests a key role for the oral microbiome in mucositis development. However, the underlying mechanisms remain elusive. In this work, we have investigated the interactions between the host, the microbiome, and chemotherapeutic treatments in more detail. The effect of 5-fluorouracil, commonly inducing mucositis, was assessed on a co-culture model that consists of an epithelial cell layer and a biofilm derived from oral microbiota from different types of samples (saliva, buccal swabs and tongue swabs) and donors (healthy individuals and patients suffering from mucositis)...

Early white matter (WM) changes are common in dementia and may contribute to functional decline. We here examine this phenomenon in an induced dementia model for the first time. We report a novel and selective form of myelin injury as the first manifestation of tauopathy in the adult central nervous system. Myelin pathology rapidly followed the induction of a P301 tau mutation associated with fronto-temporal dementia in humans (rTG4510 line). Damage involved focal disruption of the ad-axonal myelin lamella and internal oligodendrocyte tongue process, followed by myelin remodeling with features of re-myelination that included myelin thinning and internodal shortening...
