1. Clinicopathological and immunohistochemical analysis of spindle cell squamous cell carcinoma of the tongue: a rare case
RESUMO O carcinoma de células escamosas de células fusiformes da língua, é uma variante rara do carcinoma de células escamosas. Este trabalho relata o caso de um paciente do sexo masculino de 64 anos de idade com carcinoma de células escamosas de células fusiformes da língua. Foi feita uma revisão dos aspectos relacionados a etiopatogenia, caracter�

2. Head and Neck Lymphomas in HIV Patients: a Clinical Perspective
Abstract Introduction Because of the many HIV-related malignancies, the diagnosis and treatment of lymphoma in patients infected with human immunodeficiency virus are challenging. Objective Here, we review current knowledge of the pathogenesis, epidemiology, symptomatology, diagnosis, and treatment of head and neck lymphomas in HIV patients from a clinic

3. The accuracy of fine-needle aspiration cytology for diagnosis of parotid gland masses: a clinicopathological study of 114 patients
ABSTRACT Objective Fine-needle aspiration cytology is a valuable method for preoperative assessment of head and neck tumors. However, its accuracy in detection of salivary gland masses is controversial compared with other methods. The aim of this work was to evaluate the effectiveness and accuracy of fine-needle aspiration cytology (FNAC) in the diagnosis

4. Adesão e atividade de protease são reguladas pelo peptídeo derivado da laminina AG73, sindecan-1 e integrina 1 em linhagem celular derivada de carcinoma adenóide cístico / Ahesion and protease activity are regulated by the laminin-derived peptide AG73, syndecan-1 and bintegrin in cell line derived from adenoid cystic carcinoma.
We studied induction of MMP activity by b1-laminin peptide AG73 in adenoid cystic carcinoma cell line (CAC2). Cells grown inside AG73-enriched laminin-111 exhibited pseudocystics spaces. MMP inhibitor decreased those spaces, suggesting MMPs action. Cells grown on AG73 showed a dose-dependent increase of MMP9 secretion. MMP9 siRNAi decreased remodeling in 3D

5. 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

6. 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,

7. Undifferentiated carcinoma of parotid gland.
Two cases of undifferentiated carcinomas of the major salivary glands were studied using immunohistochemical techniques. Results showed that this entity was a high grade malignant neoplasm arising from the excretory duct. Despite the undifferentiated appearance multiple immunophenotypes were evident in both cases.

8. Myoepithelial carcinoma (malignant myoepithelioma) of the parotid gland arising in a pleomorphic adenoma.
A myoepithelial carcinoma, a rare malignant salivary gland neoplasm, arose in a pleomorphic adenoma of the parotid gland. The initial tumour was a pleomorphic adenoma with epithelial and myoepithelial elements. Subsequently the tumour recurred twice and was characterised by invasion of the mandible. Histological examination of the second recurrence showed a

9. Epithelial-myoepithelial carcinoma of salivary glands.
Four cases of epithelial-myoepithelial carcinoma of the salivary glands arose as painless masses in patients over 60 years old, three in the parotid and one in the submandibular gland. Histologically, all the tumours were composed of small ducts with a double cell lining surrounded by a basement membrane. The inner cells were epithelial and the outer cells m
