1. Análise da via do Akt em neoplasias benignas e malignas de glândulas salivares / Analisys of Akt pathway in benign and malignant salivary galnd tumours
A proteína Akt modula a função de numerosos substratos envolvidos na regulação da sobrevivência celular, progressão do ciclo celular e crescimento celular. Estudos prévios realizados em nosso laboratório demonstraram a superexpressão de Akt em adenoma pleomórfico, mioepitelioma e carcinoma adenóide cístico. O objetivo deste estudo foi analisar a

2. 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

4. Histological reclassification of 101 intraoral salivary gland tumours (new WHO classification).
The epithelial salivary gland tumours have for many years been categorised according to the 1972 World Health Organisation (WHO) classification. In 1990 a proposed revision of this classification was elaborated. In this study 101 intraoral salivary gland tumours were reclassified accordingly. In 29 of the cases the original histological diagnosis was changed

5. Intraduct papilloma of parotid gland.
Intraduct papillomas of the salivary glands are rare solitary tumours. Most of the reported cases have occurred in minor salivary glands. A case which occurred in the parotid gland is reported. Fine needle aspiration was performed on this tumour, and the cytological appearances of the aspirate were suggestive of an adenoid cystic carcinoma. This is an import

6. Tyrosine crystals in salivary gland tumours.
Tyrosine crystals were seen in 24 of 113 salivary gland pleomorphic adenomas from Malawi and one of six carcinomas arising in a pleomorphic adenoma; they were present in tumours from all common anatomical sites. They were not found in 71 other salivary tumours of varying histological type. Similar crystals were found in one out of 56 pleomorphic adenomas fro

7. Immunoreactivity of alpha smooth muscle actin in salivary gland tumours: a comparison with S100 protein.
Antibodies against alpha smooth muscle actin (ASMA) and S100 protein were applied to paraffin wax embedded sections from 40 salivary gland tumours and seven normal salivary glands. The results indicate that ASMA is useful in the diagnosis of epithelial-myoepithelial carcinoma, but is otherwise only of limited use in diagnostic practice. An unexpected finding

11. Primary endocrine carcinoma of the parotid salivary gland associated with a lung carcinoid: a possible new association.
An endocrine carcinoma of the left parotid salivary gland in a 58-year-old woman is reported. The tumour displayed a large argyrophilic cell-component and at ultrastructural level endocrine-like granules (ELG) were evident. As endocrine-paracrine cells are not normally present in the parotid, it is suggested that the endocrine elements may have been derived

12. Parotitis with secondary syphilis: a case report.
Painless swelling of the parotid salivary gland was observed in a patient presenting with secondary syphilis. This case is of special interest to venereologists and surgeons as parotitis associated with syphilis may be mistaken for common tumours of the parotid glands. A diagnosis of syphilitic parotitis should be considered in patients presenting with swoll
