Case report A 71-year-old Caucasian female first presented in November 1977 with a painless swelling of the right parotid region of 9 months' duration. Examination demonstrated a pulsatile, mobile swelling situated just below the right angle of mandible, approximately 4 cm in diameter (Fig. 1). The swelling showed the sign of emptying. In addition, a right Horner's syndrome was noted. No bruit ...

BACKGROUND Suprahyoid neck lesions are difficult to assess only by means of clinical inspection and therefore imaging techniques are required to precisely evaluate suprahyoid neck spaces. The aim of this study was to evaluate the distinctive role of computed tomography in the assessment of anatomical source and pathological type of masses involving the suprahyoid neck spaces. MATERIAL/METHODS...

Nicotine has been reported to increase the intracellular Ca concentration ([Ca]i) in sublingual acini due to neurotransmitter release from nerve terminals associated with the cell preparation (1). However, it is unclear whether or not the same reaction exists in parotid cells. Therefore, we investigated effect of nicotine on Ca mobilization in digested parotid acini from rats. After removing th...

BACKGROUND although several reports indicate that qualitative and quantitative assessments of parotid salivary function are age-stable in healthy adults, there have been no studies of the influence of age on the variability of repeated parotid flow rates. OBJECTIVE to examine the influence of age on the variability of repeated parotid flow rates in unmedicated, healthy adults. MATERIALS AND...

Human papillomavirus (HPV) infection has been shown to be associated with human tumorigenesis. The aim of the present study was to demonstrate the association between HPV infection and parotid gland tumors. Paraffin-embedded tissue sections from 59 cases of parotid gland tumors and 20 normal oral mucosa were subjected to DNA extraction and flow-through hybridization and gene chip technology to ...

AIMS To investigate 3 cases of chronic parotitis secondary to an acute bend in Stensen's duct caused by an enlargement of the masseteric space. RESULTS Three female patients presented with symptoms consistent with obstructive parotitis including glandular swelling and tenderness during meals. A 10-year-old patient had unilateral facial swelling with enlargement of the masseter muscle and mand...

conclusions a complete immunohistochemical study should be considered in cases of malignant salivary gland tumors. to reduce the recurrence rate of these tumors, the optimum therapies are radiotherapy and chemotherapy. introduction salivary gland tumors are rare head and neck lesions. the majority are benign, with only 20% of cases malignant. an epithelial-myoepithelial carcinoma is a rare low-...

by increasing number of vessels. salivary gland tumors are uncommon and their overall incidence is about 3 per 100000 per year. salivary gland hemangioma makes up 1 % of all salivary gland tumors. trismus resulting from parotid hemangioma is so rare. the patient was a 6-month-old boy with a huge lesion in his right parotid who referred to shahid sadoughi hospital of yazd, iran. the lesion appea...

Introduction: Parotid glands contain adipose cells in the alveolar connective tissue and sebaceous glands that release lipid-secretary sebum [1]. The effect of parotid fat on parotid ADC measurement has been unavoidably neglected by the single-shot spin-echo echoplanar diffusion-weighted imaging (EP-DWI), which is essentially equipped by fat-saturation to eliminate chemical shift artifact. Unde...
