13. Expression of Ki-67 protein and glycoprotein MUC1 in carcinomas of minor salivary gland mucoepidermoid / Expressão da proteína Ki-67 e da glicoproteína MUC1 em carcinomas mucoepidermóide de glândulas salivares menores
Aims: Investigate the prognostic significance of cellular proliferation indexes and mucosecretional activity in Mucoepidermoid Carcinoma (MEC) of oral cavity minor salivary glands using the immunoexpression of the protein Ki-67 and the glycoprotein MUC1 in young people and adults, by correlating these markers to clinical and pathological parameters.

14. Avaliação clinica e histopatologica de tumores da glandula parotida / Clinical and histopathological analysis of parotid gland tumors
Salivary gland tumors are rare, with an annual incidence of about 0,4 to 13,5 cases per 100000 people. Most of the cases affect the parotid gland, representing 64% to 80% of the cases and the majority is benign. The aim of this study was to analyze the main clinical and histopathological features of parotid gland tumors. We select all the patients with prima

15. 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

16. Immunohistochemical expression of cytokeratins and smooth muscle actin in salivary gland mucoepidermoid carcinomas in its differents histologic gradings of malignancy / Expressão imunohistoquimica de citoqueratinas e actina de musculo liso em carcinomas mucoepidermoides de glandulas salivares em suas diferentes gradações histologicas
O carcinoma mucoepidermóide (CME) é a neoplasia maligna de glândulas salivares mais comum, apresentando grande diversidade de tipos celulares e histogênese incerta e controversa. O objetivo deste trabalho foi avaliar a expressão imunohistoquímica de citoqueratinas (CKs) de epitélios simples (CKs 7, 8, 18 e 19) e de epitélios complexos (CKs 6, 13 e 14

17. 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

18. Predictive factors and prognostic importance of limph node metastasis in salivary gland carcionomas / Fatores preditivos e importancia prognostica das metastases linfonodais em carcinomas das glandulas salivares
Benign and malignant salivary gland neoplasias comprises 4?10% of all the neoplasias affecting humans. The parotid glands are the most commonly affected, followed by minor salivary and submandibular glands. Regional metastasis, tumor extension, presence of pain, and age older than 55 years have been considered poor prognostic indicators. The aim of this stud

19. 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

20. Histopathological and immunohistochemical study of salivary gland tumors / Estudo histopatologico e imunohistoquimico de tumores de glandulas salivares
Além de incomuns, os tumores de glândulas salivares despertam interesses por apresentarem uma grande diversidade histológica, morfológica e de comportamento biológico. Nas últimas décadas vários estudos têm mostrado que tais diversidades estão relacionadas ao acúmulo de alterações genéticas. As investigações de tais alterações são importan

21. Estudo imunohistoquimico e analise univariada dos fatores prognosticos de tumores de glandula submandibular
The aim of this work was to analyze c1inocopathological and immunohistochemical expression in submandibular salivary gland tumors. A total of 112 tumors was evaluated, being 61 benign and 51 malignant. The benign tumors were compose of 60 pleomorphic adenomas and 1 basal cell adenoma. Among the malignancies, 23 were adenoid cystic carcinoma, 16 mucoepidermoi

22. Estudo imunohistoquimico e analise multivariada de fatores prognosticos de carcinomas mucoepidermoides de glandulas salivares
Clinical staging and histological grade have been reported as the main prognostic factors in mucoepidermoid carcinoma (MEC). The aim of this study was to report clinical, pathological and immunohistochemical features as prognostic factors in head and neck MEC. From 1953 to 1997, 173 cases of head and neck MEC were retrieved from the files of the A. C. Camarg

23. Proliferating cell nuclear antigen expression in mucoepidermoid carcinoma of salivary glands
CONTEXTO: As características citológicas e morfológicas do Carcinoma Mucoepidermóide, um dos critérios mais importantes na aferição do seu comprometimento biológico e agressividade é a proliferação celular. Daí, a utilização do uso de marcadores imunohistoquímicos da proliferação celular na classificação dos tumores e na determinação do

24. Peripheral mucoepidermoid tumour of the lung.
Mucoepidermoid tumours of the bronchial tree are uncommon neoplasms, which are believed to arise from terminal ducts of the proximal tracheobronchial tree. The first case of a peripheral mucoepidermoid tumour of the lung is reported.
