Review of Salivary Gland Neoplasms
Salivary gland tumours most often present as painless enlarging masses. Most are located in the parotid glands and most are benign. The principal hurdle in their management lies in the difficulty in distinguishing benign from malignant tumours. Investigations such as fine needle aspiration cytology and MRI scans provide some useful information, but most cases will require surgical excision as a...
متن کاملPitfalls in the biopsy diagnosis of intraoral minor salivary gland neoplasms: diagnostic considerations and recommended approach.
Among the more common types of intraoral minor salivary gland neoplasms are pleomorphic adenoma, basal cell adenoma, polymorphous low-grade adenocarcinoma, and adenoid cystic carcinoma. These minor salivary gland neoplasms share similar morphologic features and to a large extent immunohistochemical findings. Differentiation between these benign and malignant neoplasms is often predicated on the...
متن کاملTP53 mutations in salivary gland neoplasms.
Many studies have demonstrated that loss of TP53 gene function has an important role in the genesis of many neoplasms, including salivary gland neoplasms. The purpose of this study was to examine the mutation profile of the TP53 gene in salivary gland neoplasms. Genomic DNA was extracted from paraffin-embedded tissues of pleomorphic adenoma, carcinoma in pleomorphic adenoma, mucoepidermoid carc...

AIM The aim of the present study is to establish the relative frequency and distribution of benign and malignant epithelial neoplasms of salivary glands in the Pathology and Cytology Laboratory, STUDY DESIGN Historic cohort. MATERIAL AND METHOD in the state of Sergipe, during the period 1980-1999. The neoplasms were individualized by gender, age, race of the patients, anatomic localization ...
متن کاملImmunolocalization of DNMT1 and DNMT3a in salivary gland neoplasms.
OBJECTIVE Salivary gland neoplasms pathogenesis has not been well established. DNA methylation occurs when methyl groups are added to cytosine nucleotides in specific areas of the gene by the enzyme DNA methyltransferase (DNMT). This chemical modification can alter gene expression without altering DNA sequence. While DNMT3a is mostly involved in de novo methylation, DNMT1 acts as a maintenance ...
