We determined mRNA levels of bone morphogenetic protein 7 (BMP7), a growth and differentiation factor belonging to the transforming growth factor-beta superfamily, in the salivary glands of mice with streptozotocin (200 mg/kg, i.p.)-induced diabetes. We also examined the effects of BMP7 on secretion of saliva and degenerative change in salivary glands in diabetic mice. In normal mice, BMP7 mRNA...

BACKGROUND Complete tumor removal and preservation of the facial nerve are essential in parotid gland surgery. A technical adjunct that potentially enhances the contrast between the facial nerve and the adherent tumor tissue and allows to identify residual tumor tissue could be Fluorescein Sodium. METHODS Retrospective chart analysis on 7 patients with benign parotid gland lesions that were o...

Painless swelling of the parotid salivary gland was observed in a patient presenting with secondary syphilis. This case is of special interest to venereologists and surgeons as parotitis associated with syphilis may be mistaken for common tumours of the parotid glands. A diagnosis of syphilitic parotitis should be considered in patients presenting with swollen parotid salivary glands in countri...

Objective Fine-needle aspiration cytology is a valuable method for preoperative assessment of head and neck tumors. However, its accuracy in detection of salivary gland masses is controversial compared with other methods. The aim of this work was to evaluate the effectiveness and accuracy of fine-needle aspiration cytology (FNAC) in the diagnosis of parotid gland masses. Material and Methods ...

In the last decade, many efforts have been made to characterize anatomic changes of head and neck organs at risk (OARs) and the dosimetric consequences during radiotherapy. This review was undertaken to provide an overview of the magnitude and frequency of these effects, and to investigate whether we could find criteria to identify head and neck cancer patients who may benefit from adaptive rad...

INTRODUCTION The parotid gland and the great cervical veins are very rarely involved in a metastatic thyroid cancer. CASE PRESENTATION We report an interesting case of an unusual metastasis of a thyroid follicular carcinoma including the histopathological and radiological findings. A woman was seen in the otolaryngology clinic with a mass at the angle of the left side of her jaw. Clinical exa...

A 67-year-old male with three synchronous tumors in the unilateral parotid gland is reported. Postoperative histological examinations confirmed the presence of three synchronous primary tumors, specifically pleomorphic adenoma, Warthin's tumor and salivary duct carcinoma, in the right parotid gland. To our knowledge, this is the first case report describing three different histological types in...

background: salivary gland tumors are relatively uncommon and they consist of 3-10% of head and neck neoplasms. most of studies have shown geographic variation in the incidence and histopathologic types of salivary gland neoplasms. the aim of this study was to evaluate the salivary gland tumors in isfahan for 10 years duration. materials and methods: in this epidemiological study, 229 medical r...

ACCs are usually low grade, well‐differentiated neoplasms that constitute 2.5%–4% of parotid gland tumors.[1] The mean age of occurrence is in the fifth decade, but the papillary cystic variant is reported to occur in younger patients compared to the classic type. The most favored site is the parotid (86%), occasionally the submaxillary gland, minor salivary glands.[1] ACC is a neoplastic growt...
