25. Galectin-3 immunoprofile in adenoid cystic carcinoma and polymorphous low-grade adenocarcinoma of salivary glands / "Expressão imunoistoquímica da proteína galectina-3 em carcinoma adenóide cístico e adenocarcinoma polimorfo de baixo grau de malignidade de glândulas salivares"
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

26. Evaluation of expression of MDM2, P53, P21WAF1 in adenoid cystic carcinoma and adenocarcinoma not otherwise specified of salivary glands / Avaliação da expressão das proteínasMDM2, P53, P21WAF1 e pAKT em carinoma adenóide cístico e adenocarcinoma de glândulas salivares
As proteínas MDM2, P53, P21 e pAKT estão entre as muitas já identificadas que visam, por meio do equilíbrio direto e indireto entre si, manter o balanço entre morte e proliferação celular. Existe um leque aberto de hipóteses sobre a via de atuação dessas proteínas na tumorigênese de glândulas salivares, porém não há dados conclusivos. O objet

27. 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

28. 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,

29. Estudo imunohistoquimico e analise multivariada de fatores prognosticos em carcinoma adenoide cistico de cabeça e pescoço
Introduction: The aim of this study was to analyze the clinical, histological and immunohistochemical prognostic factors of a large series of adenoid cystic carcinoma treated in a single institution, using univariate and multivariate survival analyses. Methods: All cases of head and neck ACC treated between 1955 and 1997, at the Department of the Head and Ne

30. 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

31. Adenoid cystic carcinoma of the oesophagus.
A case of adenoid cystic carcinoma of the oesophagus occurring in a patient who had previously been treated for craniopharyngioma is presented. This is the thirteenth reported case of adenoid cystic carcinoma of the oesophagus and the first in association with craniopharyngioma. The previously described cases of oesophageal adenoid cystic carcinoma are criti

32. Laminin and fibronectin in adenoid cystic carcinoma.
The distribution of fibronectin and laminin was examined by immunohistochemistry in 11 adenoid cystic breast carcinomas, six adenoid cystic carcinomas of mouth and salivary gland, and six cribriform ductal breast carcinomas. Both proteins were present lining cystic lumina and around tumour islands in all the adenoid cystic breast carcinomas and in five of si

33. Peripheral pulmonary adenoid cystic carcinoma with substantial submucosal extension to the proximal bronchus.
A rare case of a peripheral pulmonary adenoid cystic carcinoma is presented. Histological examination after lobectomy showed pronounced submucosal invasion of the carcinoma to proximal bronchi.

34. Detection of integrated high risk human papillomavirus in adenoid cystic carcinoma of the uterine cervix.
AIM: To investigate the role of human papillomavirus (HPV) in adenoid cystic carcinoma of the uterine cervix. METHODS: Eleven archival, paraffin wax embedded specimens were analysed by non-isotopic in situ hybridisation (NISH) for HPV types 6, 11, 16, 18, 31, and 33 using digoxigenin labelled probes. The polymerase chain reaction (PCR) was carried out on eac

35. Primary malignant neoplasms of the lacrimal gland.
The clinical characteristics and outcome of 50 primary malignant neoplasms of the lacrimal gland are reviewed: 38 (76%) adenoid cystic carcinomas, six (12%) carcinomas arising in pleomorphic adenoma, and six (12%) adenocarcinomas or other types of carcinoma. Most patients presented with a short history and pain, though pain tended to occur less often and lat

36. Adenoid cystic carcinoma of the breast: prevalence, diagnostic criteria, and histogenesis.
Three cases of adenoid cystic carcinoma have been identified in a 10-year review of 2686 cases of breast carcinoma. The criteria necessary for diagnosis have been reviewed with particular reference to cribriform intraduct carcinoma and adenocarcinoma of the breast with small, dark, 'basaloid'-cell pattern. The most important single diagnostic criterion of ad
