1. 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

2. 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

3. Papel de peptídeos bioativos da laminina na atividade dos invadopódios em linhagem celular derivada de carcinoma adenóide cístico. / Role of laminin-111 derived peptides in invadopodia activity of a human adenoid cystic carcinoma cell line.
Carcinoma adenóide cístico é uma neoplasia maligna de glândula salivar com alto grau de recorrência e metástase. Células tumorais que invadem tecidos subjacentes formam invadopódios, protrusões de membrana ricas em actina, cortactina e MT1-MMP capazes de degradar a matriz extracelular (MEC). Proteólise de moléculas da MEC, como a laminina, promove

4. âEstudo epidemiolÃgico de lesÃes orais em laboratÃrios de anÃtomo patologia na cidade de Fortaleza-Ceâ / Epidiological study of oral lesion in anatomopathological laboratories in Fortaleza-Ce
A wide range of diseases can affect the oral cavity, from developmental defects to metastasizing malignant neoplasms. The knowledge on Oral Pathologies`s prevalence helps the clinician making differential diagnosis. The aim of this study was to perform an epidemiological survey of oral lesions in five anatomopathological laboratories in Fortaleza, CearÃ, Br

5. Efeito de duas formulaÃÃes de pilocarpina, soluÃÃo para bochecho e sublingual, no tratamento da Xerostomia induzida por radiaÃÃo / Effect of two formulations of pilocarpine, mouthwashing and sublingual solutions, for the treatment of radiation induced xerostomia
A prospective and double-blind study was conducted to verify the effects of the use of pilocarpine in the treatment of xerostomy induced by irradiation in oncologic patients, testing two administration routes: sublingual and mouthful. The volunteers were randomly allocated in two groups: a group for use of mouthfuls and a group for use of sublingual solution

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. 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

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. Carcinoma mucoepidermóide de glândulas salivares:: características clinicopatológicas e imunoexpressão de c-erbB-2
Salivary glands tumors are rare and morphologically diversified, so, there are few papers about only one histologic type. Mucoepidermoid carcinoma (MEC) is the most common malignant neoplasm of major and minor salivary glands. The histological appearance of MEC is diversified and is correlated with the biological behavior of the tumor. Oncogene c-erbB-2 pres

To determine the main factors influencing the biological behavior of 40 squamous cell carcinomas (SCC) of the upper digestive tract (UDT) of cattle associated with spontaneous ingestion of bracken fern (Pteridium aquilinum), morphological, including cell proliferation, and immunohistochemical aspects were studied. The aspects analyzed included anatomical loc

Adenoid cystic carcinoma and polymorphous low-grade adenocarcinoma are malignant neoplasms of salivary glands which are similar in histologic patterns but very different in clinical behavior, treatment and prognosis. Galectin-3 is a multifunctional protein of a growing family of beta-galactoside-binding animal lectins which is implicated in a variety of biol

Expressão imuno-histoquímica das integrinas a2ß1, a3ß1 e a5ß1 em adenoma pleomórfico de glândula salivar menor e maior e carcinoma adenóide cístico / Immunohistochemical expression of D2E1, D3E1 e D5E1 integrins in pleomorphic adenoma from minor and major salivary glands and adenoid cystic carcinoma
Pleomorphic adenoma and adenoid cystic carcinoma (ACC) consist benign and malignant neoplasm from salivary gland, respectively. These neoplasms share some characteristics, such as cellular origin and considerable production of extracellular matrix, however, with distinct biological behavior. The aim of the present study was to compare the expression of D2E1,
