OBJECTIVES To present 2 cases of neuroendocrine tumors of the parotid gland and to review the clinical presentation, histopathologic, and immunohistochemical findings and treatment of these rare tumors. STUDY DESIGN Case series. METHODS This study reviews 2 patients who both presented with firm masses in the parotid gland diagnosed as neuroendocrine carcinoma by histopathologic and immunohi...

Parotid gland tumours have evolved much interest arid debate because of the variability of their structure and behaviour. The biological patterns in any given tumour vary from field to field. Thus most malignant mixed salivary tumours will contain both areas of completely benign mixed tumour and areas of overt carcinoma.80-90% salivary tumour arise in the major gland about 70-85% being in the p...

the use of panoramic radiography, due to its numerous advantages, is increasing. radiographic films used in this technique are of double emulsion (de) type which are used with intensifying screens. single emulsion (se) films can also be used. the purpose of this study was to determine the exposure parameters to achieve an appropriate optical density in these two types of films, and to estimate ...

PURPOSE To estimate dose-response relationship using dynamic quantitative (99m)Tc-pertechnate scintigraphy in head-neck cancer patients treated with parotid-sparing conformal radiotherapy. METHODS Dynamic quantitative pertechnate salivary scintigraphy was performed pre-treatment and subsequently periodically after definitive radiotherapy. Reduction in salivary function following radiotherapy ...

BACKGROUND Our objective was to evaluate the outcome of patients treated for squamous cell carcinoma (SCC) of the parotid gland. METHODS We conducted a retrospective chart review of the tumor registry from 1982 through 2003 at a tertiary referral medical center. Patients with SCC of the parotid gland were identified and followed for a minimum of 2 years after therapy. RESULTS SCC involving ...

UNLABELLED Parotid gland parenchyma histology may be altered by local or systemic, pathological or nonpathological conditions. OBJECTIVE This paper aims to highlight the fatty degeneration of the parotid gland, a not well-known non-pathological condition. METHOD In a retrospective study, we collected a series of 6 patients which presented a swelling of the parotid, but even after extensive ...

PURPOSE Our practice policy has been to provide intraoperative radiotherapy (IORT) at resection to patients with head-and-neck malignancies considered to be at high risk of recurrence. The purpose of the present study was to review our experience with the use of IORT for primary or recurrent cancer of the parotid gland. METHODS AND MATERIALS Between 1982 and 2007, 96 patients were treated wit...

PURPOSE To review the CT and MR characteristics of temporal bone malignancy, and to evaluate the relationship between malignancies of the temporal bone and parotid gland. METHODS A group of 15 surgical patients with diagnosis of temporal bone malignancy were retrospectively reviewed. These included 11 cases of primary temporal bone malignancy and four cases of secondary carcinoma of the tempo...

OBJECTIVE In the current study, we examined whether selenium supplementation during iodine-131 (131I) treatment had a radio-protective effect on salivary glands. SUBJECTS AND METHODS Sixteen patients with differentiated thyroid cancer were prospectively enrolled in the study. Patients after total thyroidectomy, before 131I treatment, were divided into two groups; 8 patients in the selenium gr...
