1. Perfusion Computed Tomography Scan Imaging in Differentiation of Benign from Malignant Parotid Lesions
Abstract Introduction The most common site of salivary gland tumors is the parotid gland. Computed tomography (CT), magnetic resonance imaging (MRI), and sonography are imaging modalities to differentiate benign from malignant parotid tumors. Objective The aim of this study is the evaluation of the diagnostic value of perfusion CT for differentiating his

2. The value of fine needle aspiration cytology in the clinical management of rare salivary gland tumors
Abstract Salivary gland tumors are relatively rare neoplasms, mostly located in the parotid gland, and few are malignant. Preoperative evaluation of salivary gland tumors includes fine needle aspiration cytology (FNAC). Objective The purpose of this study was to determine the importance of FNAC in the evaluation of rare salivary gland neoplasms. Material a

3. DNA Aneuploidy in Malignant Salivary Gland Neoplasms is Independent of USP44 Protein Expression
Resumo Instabilidade cromossômica acarretando aneuploidia é um dos fatores marcantes de neoplasias malignas humanas. USP44 (peptidase específica de ubiquitina 44) é uma importante molécula que exerce um papel regulador no ciclo celular e sua perda pode acarretar em segregação cromossômica deficiente, aneuploidia e desenvolvimento de tumores in vivo.

4. Clinicopathological analysis of salivary gland tumors over a 15-year period
Abstract Salivary gland tumors (SGT) are rare neoplasms that generate interest due to their histopathological diversity and clinical behavior. The aims of the present study were to investigate clinicopathological aspects of SGTs diagnosed at a tertiary health center and compare the findings with epidemiological data from different geographic locations. Cases

5. Effect of fractionated radiotherapy on the parotid gland: an experimental study in Brazilian minipigs
INTRODUCTION: Radiotherapy (RT) of head and neck neoplasms often damages the salivary glands. AIM: To examine the pattern of morphologic changes resulting from RT of the head and neck region in minipig parotid glands in a clinical and experimental research setting. METHODS: Twelve 18-month-old male Brazilian minipigs weighing 30-40 kg were selected. Eight mi

6. Estudo retrospectivo de 3091 casos de neoplasias epiteliais primarias de glandulas salivares maiores e menores intra-orais / Retrospective study of 3091 cases of primary epithelial salivary gland tumors involving the major and minor glands
The aim of this study was to analyse retrospectively the histological and epidemiological characteristics of 3091 cases of intraoral primary epithelial neoplasms of the minor and major salivary glands. It was included on this study, 1766 cases from Brazil, 544 from the U.S., 405 from Uruguay, 151 from Peru, 134 from Guatemala and 91 from Mexico. Benign tumor

7. Salivary neoplasias with myoepithelial differentiation : immunoexpression study of the CD10 (CALLA/NEP 24.11) and podoplanin (D2-40) / Neoplasias salivares com diferenciação mioepitelial : estudo da imunoexpressão do CD10 (CALLA/NEP 24.11) e da podoplanina (D2-40)
CD10 e Podoplanina (D2-40), além de expressos nas células mioepiteliais, estão envolvidos na progressão tumoral e podem ser utilizados como marcadores prognósticos. Em 79 neoplasias salivares com diferenciação mioepitelial (44 malignas e 35 benignas), analisamos a expressão dessas proteínas nas células neoplásicas, na reação desmoplásica tumora

8. Estudo clínico-epidemiológico de neoplasias de glândula salivar menor no estado da Bahia. / Intraoral menor salivary gland tumors in a Brazilian population: a retrospective study
Minor salivary gland tumors are relatively rare and comprise a diverse group of neoplasms exhibiting complex morphology. The aim of this study was to investigate the clinical and epidemiological features of the minor salivary gland tumors diagnosed at Aristides Maltez Hospital, Salvador, Bahia, between 1976 and 2007. Data regarding the age and sex distributi

9. c-Jun and junB immunoprofile in adenoid cystic carcinoma and polymorphous low-grade adenocarcinoma of salivary glands / Estudo da imunoexpressão das proteínas C-JUN e JUNB em carcinoma adenóide cístico e adenocarcinoma polimorfo de baixo grau de malignidade de glândulas salivares
Adenoid cystic carcinoma and polymorphous low grade are salivary gland neoplasms. ACC can arise in both, major or minor salivary glands. However, Polymorphous lowgrade adenocarcinoma, occurs specifically in minor salivary glands dispersed in the oral cavity. They share many common histologic features, as infiltrating solid, tubular and cribiform patterns and

10. Alterations of E-cadherin and β-catenin genes in pleomorphic adenoma and adenoid cystic carcinoma: molecular and immunohistochemical study / Alterações nos genes da E-caderina e β-catenina em adenoma pleomórfico e carcinoma adenóide cístico: estudo molecular e imuno-histoquímico
Pleomorphic adenoma and adenoid cystic carcinoma represent a benign and malignant salivary gland neoplasm, respectively, that shares the same histological origin, however with distinct biological behavior. The aim of the present study was identify the -160 C/A polymorphism in the gene CDH1, mutational analysis of CTNNB1 gene and evaluation the expression of

11. Prognostic factors in salvage surgery for recurrent salivary gland carcinoma / Fatores prognósticos em carcinomas de glândulas salivares recidivados submetidos à cirurgia de resgate
Salivary gland carcinomas are rare and the main treatment option is surgery with or without postoperative radiotherapy. Almost half of the cases present recurrences of tumors and the majority are local. The only potentially curative treatment for recurrent tumors is salvage surgery. However, few papers were published on this subject. The aim of this study is

12. Avaliação do potencial metastático e da vascularização nas neoplasias epiteliais de glândulas salivares.
Tumoral angiogenesis represents a potential bimolecular marker for prognosis and predictive factor for metastasis in human solid tumors. Recently, endothelial markers and growth vascular factors such as the vascular endothelial growth factor (VEGF) and the platelet derived endothelial growth factor (PDEGF), as well as the vascular endothelial markers CD34 an
