Epithelio-myoepithelial carcinoma (EMEC) is a very rare malignancy of the salivary gland which comprises less than 1 % of salivary gland tumors. In the parapharyngeal space they can either arise from the deep lobe of parotid gland or de novo from minor salivary glands. We present a case of epithelio-myoepithelial carcinoma of parapharyngeal and masseteric space. The case is important for its rarity of presentation and we discuss the surgical difficulties and morbidities.

BACKGROUND: Shear wave elastography is a relatively new method of quantitative measurement of tissue elasticity. Assuming that malignant lesions are stiffer than benign ones, elastography may provide supplementary information for their discrimination. However, potential confounding factors impacting tissue stiffness should be investigated first. AIMS: The objective of this study was to measure the stiffness of selected tissues of the head and neck in a normal population and to evaluate its relationship to age, sex, and body mass index...

Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Simultaneous involvement of the thyroid gland by multiple malignancies, is a rare occurrence. Similarly, primary thyroid lymphomas are also rare. We are reporting a rare case of a dual thyroid malignancy; PTC with secondary thyroid involvement by chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), diagnosed on cytology and confirmed with flow cytometry, histology and immunohistochemistry. Imaging showed two hypermetabolic nodules, one in left parotid gland, and the other in the thyroid isthmus...

Malignant non-basaloid tumors that arise from basal cell adenoma (BCA) are extremely rare. The patient was a 72-year-old Japanese male, who had noticed swelling of the left parotid region 21 years ago. A superficial lobectomy was performed. About 60% of the tumor was made up of cribriform and trabecular tissue composed of basaloid cells, which exhibited mild atypia and nuclear expression of β-catenin. This portion of the tumor was considered to be a BCA. In the other part of the tumor, the proliferation of large eosinophilic atypical cells, most of which formed intraductal structures, was observed...

OBJECTIVES: Preferential use of fine-needle aspiration (FNA) versus core needle biopsy (CNB) for distinguishing benign from malignant major salivary gland tumors is highly debated. The main disadvantage of FNA is lower sensitivity, whereas arguments against CNB include use of a larger bore needle and greater risk of complications. The aim of this study is to evaluate our experience performing ultrasound-guided (UG) FNA with selective use of CNB based on preliminary cytopathology, and to determine whether our preoperative diagnostic approach is more sensitive and specific than FNA alone-and at least as sensitive and specific as CNB alone...

The dental follicle (DF), most often associated with unerupted teeth, is a condensation of ectomesenchymal cells that surrounds the tooth germ in early stages of tooth development. In the present study, we aim to isolate epithelial stem-like cells from the human DF and explore their potential differentiation into salivary gland (SG) cells. We demonstrated the expression of stem cell-related genes in the epithelial components of human DF tissues, and these epithelial progenitor cells could be isolated and ex vivo expanded in a reproducible manner...

We undertook a re-analysis of the Canadian data from the thirteen-country INTERPHONE case-control study (2001-2004), which evaluated the association between mobile phone use and risk of brain, acoustic neuroma, and parotid gland tumors. The main publication of the multinational INTERPHONE study concluded that "biases and errors prevent a causal interpretation". We applied a probabilistic multiple-bias model to address possible biases simultaneously, using validation data from billing records and non-participant questionnaires as information on recall error and selective participation...

PURPOSE: To present the clinical features of patients with parotid gland metastasis, and compare the results with previously published series. Most of the relevant literature arises from case reports, while there are only few series reported, as secondary neoplastic lesions of the parotid gland are uncommon. METHODS: The medical records of patients with parotid gland metastasis, treated at the ENT Department of the University Hospital of Ferrara, between January 1st 1965 and December 31th 2014, were retrospectively reviewed...

The technique of jaw tracking can be used in volumetric modulated arc therapy (VMAT) and intensity modulated radiation therapy (IMRT). In this technique, jaw tracks apertures of the multi leaf collimator (MLC) during irradiation. It is reported that dose variation is occurred by the changing accuracy of MLC position in VMAT and IMRT. Though jaw moves dynamically in the irradiation by using this technique, the influence of the jaw position accuracy on dose variation is not examined. The purpose of this study is to verify the influence of jaw position accuracy on dose variation in VMAT using jaw tracking...

OBJECTIVES: Salivary acinar and duct cells show different expression patterns of claudins, which may reflect their different functions. To study the role of claudins in saliva secretion, we examined alterations in the expression patterns of cell adhesion molecules in parotid glands of γ-irradiated rats and analyzed the influence of those changes on intercellular barrier function using primary cultures of parotid acinar cells. DESIGN: Rats were γ-irradiated with doses of 5, 15 or 20Gy, and expression levels of cell adhesion molecules were examined by immunoblotting analysis...

Repeated haemorrhages in peripheral nerve sheath tumours of the salivary glands are rare. We report the case of a patient with neurofibromatosis type 1 who had two episodes of massive haemorrhage in his right parotid gland the day after a minor injury. Oral and maxillofacial surgeons should be aware that vasculopathy may occur in patients with these tumours.

Basal cell adenoma is a rare benign salivary gland neoplasm. The most common location is in parotid region. Clinically, gradual growth and firm consistency are seen. They account for 1 to 3% among all salivary gland neoplasms. Prominent basaloid cells with cluster of isomorphic cells and interspersed trabeculae are present histopathologically. In this article, we present a rare case of basal cell adenoma of retromolar region from minor salivary gland origin.

BACKGROUND: The external carotid artery (ECA) is the main high-flow donor for extracranial-intracranial revascularization procedures. However, anatomic restraints limit the availability of ECA in posterior exposures of the craniocervical junction aimed for bypass to distal vertebral artery segments. OBJECTIVE: To examine the feasibility and safety of exposure of the ECA through the posterior triangle of the neck. METHODS: A preliminary feasibility study on the posterior neck exposure of the ECA was performed in 1 cadaveric head (2 sides) followed by a morphometric study on 9 cadaveric heads (18 sides)...
