BACKGROUND: Non-traumatic bone fractures in cancer patients are usually pathological fractures due to bone metastases. In head and neck cancer patients, clavicle stress fractures may occur as a result of atrophy of the trapezius muscle after neck dissection in which the accessory nerve becomes structurally or functionally damaged. CASE REPORT: A 71-year-old man underwent modified radical neck dissection with accessory nerve preservation and post-operative radiotherapy for submandibular lymph node metastases of tongue cancer...

Development of the secondary palate involves a complex series of embryonic events which, if disrupted, result in the common congenital anomaly cleft palate. The secondary palate forms from paired palatal shelves which grow initially vertically before elevating to a horizontal position above the tongue and fusing together in the midline via the medial edge epithelia. As the epithelia of the vertical palatal shelves are in contact with the mandibular and lingual epithelia, pathological fusions between the palate and the mandible and/or the tongue must be prevented...

Human papillomavirus (HPV) 16 is the most common high-risk HPV type identified in oropharyngeal and cervical neoplasia. Recently, HPV-associated oral epithelial dysplasia with specific histopathologic features and demographics similar to HPV-oropharyngeal carcinoma has been identified. The objective of this study was to evaluate histopathologically all cases of HPV-oral epithelial dysplasia seen in one center and identify HPV types in a subset of cases. Cases with specific histopathology for HPV-oral epithelial dysplasia that were positive both by immunohistochemical studies for p16 and by in situ hybridization for high-risk types of HPV were further analyzed using QIAamp DNA Tissue Kits (Qiagen, Hilden, Germany)...

INTRODUCTION: Recent evidence suggests that the local renin-angiotensin system has been implicated in various malignancies. The mitochondrial assembly receptor is a newly identified receptor for angiotensin peptides, angiotensin-(1-7), and has an important role in the renin-angiotensin system. However, the role of the mitochondrial assembly receptor in the prognosis of cancer patients remains unclear. The aim of this study was to evaluate the significance of mitochondrial assembly receptor signaling in the prognosis of oral tongue squamous cell carcinoma...

Macroglossia is classified as true macroglossia, which exhibits abnormal histology with clinical findings, and relative macroglossia, in which normal histology does not correlate with pathologic enlargement. This report describes an atypical case of morbidity with massive macroglossia secondary to myxedema; the macroglossia enlarged over a 3-month period before being presented to the Department of Oral and Maxillofacial Surgery, University of Texas Health Sciences Center at Houston (Houston, TX). Substantial enlargement of the tongue (16 cm long × 10 cm wide) was first attributed to angioedema, which was refractory to the discontinuation of lisinopril and a C1 esterase inhibitor...

Metabotropic glutamate receptor subtype 5 (mGluR5) is a Group I mGlu subfamily of receptors coupled to the inositol trisphosphate/diacylglycerol pathway. Like other mGluR subtypes, mGluR5s contain a phylogenetically conserved, extracellular orthosteric binding site and a more variable allosteric binding site, located on the heptahelical transmembrane domain. The mGluR5 receptor has proved to be a key pharmacological target in conditions affecting the central nervous system (CNS) but its presence outside the CNS underscores its potential role in pathologies affecting peripheral organs such as the gastrointestinal (GI) tract and accessory digestive organs such as the tongue, liver and pancreas...

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare self-limiting disorder typically affecting the cervical lymph nodes (LNs), which is often misdiagnosed as other LN-associated diseases. KFD frequently presents with necrotic lesions and recurrences, which are also features of metastatic LNs. Clinicians may thus suspect LN metastasis when they encounter ipsilateral cervical lymphadenopathy in a patient with head and neck cancer. The present study reports the case of a 48-year-old man with tongue cancer and KFD affecting the right edge of his tongue and ipsilateral cervical LNs...

Tongue strength is routinely evaluated in clinical swallowing evaluations since lingual weakness is an established contributor to dysphagia. Tongue strength may be clinically quantified by the maximum isometric tongue pressure (MIP) generated by the tongue against the palate; however, wide ranges in normal performance remain to be fully explained. Although orthodontic theory has long suggested a relation between lingual function and oral cavity dimensions, little attention has been given to the potential influence of oral and palatal structure(s) on healthy variance in MIP generation...

PURPOSE: The seventh edition of tumor staging by the American Joint Committee on Cancer (AJCC) includes extrinsic muscle involvement to define stage T4a tongue carcinomas. The anatomic location of extrinsic muscles predisposes them to early involvement even in superficial tumors. The purpose of this study was to expose a fallacy in this staging system for extrinsic muscle involvement. MATERIALS AND METHODS: This was a prospective cohort study of 87 patients with oral tongue squamous cell carcinoma...

Small cell neuroendocrine carcinoma (SCNEC) of the tongue is very rare. We here present a SCNEC impatient with distant metastasis. A 74-year-old Chinese male went to hospital to treat a tongue tumor, which was founded at a conventional physical examination in Weifang Stomatology Hospital. The check of positron emission tomography-computer tomography (PET-CT) by Weifang people's hospital revealed a tumor in the right root of tongue, and distant metastasis in the right submandibular area, neck, mediastinum, right hilar, abdominal, retroperitoneal multiple lymph nodes, left thyroid, right lower lung, right scapula and bilateral adrenal...

The feasibility and effectiveness of transoral robotic surgery (TORS) in children with tongue base masses (TBMs) were evaluated. Eight pediatric patients who were treated with TORS for TBMs between January 2010 and January 2016 at a tertiary hospital included in the study. All pathologies were congenital lesions: four were lingual thyroglossal ductus cysts (LTGDCs), one was a minor salivary gland tumor, one was a vallecular cyst, one was a bronchogenic cyst, and one was an ectopic thyroid tissue. TORS was performed successfully in all cases...

Short beak and dwarfism syndrome virus (SBDSV) is a newly emerging distinct duck-origin goose parvovirus that belongs to the genus Dependovirus. Our previous studies have found that SBDSV was highly pathogenic to Cherry Valley ducklings and mule ducklings. However, little is known about its pathogenicity to other waterfowls. In the present study, the pathogenicity of SBDSV was evaluated in domesticated waterfowl including Muscovy ducklings, Sheldrake ducklings and domestic goslings. All experimentally infected birds exhibited remarkable growth retardation, anorexia and diarrhea similar to naturally infected birds...

Salivary glands may give rise to a wide spectrum of different tumors. This review concentrates on 4 salivary gland tumors that have been accepted in the recent literature as new neoplastic entities: mammary analog secretory carcinoma, cribriform adenocarcinoma of minor salivary glands (CASG), sclerosing polycystic adenosis/adenoma (SPA), and the mucinous/secretory variant of myoepithelioma. Mammary analog secretory carcinoma is a distinctive low-grade malignant salivary cancer that harbors a characteristic chromosomal translocation, t(12;15) (p13;q25), resulting in an ETV6-NTRK3 fusion...

A 24-year-old man presented with orofacial swelling, peripheral facial palsy and fissured tongue. Apart from a previous episode of peripheral palsy, he had no history of illness. Biopsy of the lip, blood tests, magnetic resonance imaging of the head and lumbar puncture showed no pathology. He received systemic prednisone for ten days, and follow-up showed sparse improvement in facial movements. The patient could have been misdiagnosed with Bell's palsy, but the symptoms rather indicated a case of Melkersson-Rosenthal syndrome...
