The aim of this study was to investigate the radioprotective effect of thymol as a natural product against salivary glands dysfunction induced by ionizing radiation in rats. The rats were treated with thymol at dose of 50 mg/Kg before exposure to radiation at dose 15Gy. Salivary gland function was evaluated with radioisotope scintigraphy and then salivary gland to background counts ratio was ca...

Tumors of salivary glands are uncommon and comprise of about 2%-4% of all head and neck tumors. About 75%-80% of these tumors are benign and include pleomorphic adenoma, monomorphic adenoma, oncocytoma, and papillary cystadenoma lymphomatosum. Mucoepidermoid carcinoma is the most common malignant tumor of salivary glands, representing 5-10% of all salivary gland tumors. Although known to be met...

BACKGROUND Malignant tumours of minor salivary glands are uncommon, representing only 2-4% of all head and neck cancers. In the larynx, minor salivary gland tumours rarely occur and constitute less than 1% of laryngeal neoplasm. Most of the minor salivary gland tumours arise in the subglottis; however, they can also occur in the supraglottis, in the false vocal cords, aryepiglottic folds and ca...

cystadenoma is a rare benign salivary gland tumor that chiefly originates in the minor salivary glands as a cystic growth with papillary projections into the cystic lumen without the lymphoid element. it is further classified into two histopathological variants that have been recognized by world health organization as the papillary and the mucinous forms of cystadenoma. clinically, it is diffic...

"Dedifferentiation" and/or high-grade transformation (HGT) has been described in a variety of salivary gland carcinomas, including acinic cell carcinoma, adenoid cystic carcinoma, epithelial-myoepithelial carcinoma, polymorphous low-grade adenocarcinoma, myoepithelial carcinoma, low-grade mucoepidermoid carcinoma and hyalinizing clear cell carcinoma, although the phenomenon is a rare event. Rec...

Small cell carcinoma (SmCC) is a poorly diff erentiated neuroendocrine carcinoma that has been reported in several sites throughout the head and neck region, including salivary glands where it is a rare primary tumor accounting for less than 1% of all salivary gland tumors. We report a case of a 55-yearold man with problems consisting of neck pain and diffi cult swallowing induced by a retromol...

Background: Salivary gland tumors are rare and with different malignant potential. Immunohistochemistry is useful, especially Ki67, a marker of cell proliferation, for its prognostic information. On the other side, mucin MUC-1 overexpressed loses exclusively apical membranous localization aberrantly glycosylated in mucoepidermoid carcinoma salivary glands. In present work, we investigated quant...

BACKGROUND: Adenoid cystic carcinoma is an uncommon tumor of the salivary gland. Little has been published on the chemotherapy of this neoplasm. METHODS: The literature on this disease is reviewed, and data from seven unpublished cases are presented. RESULTS: Four patients received cyclophosphamide. One responded, and another had pain relief. The literature review did not identify any single dr...

BACKGROUND The purpose of this study was to analyze the pattern of occult cervical lymph node metastasis among patients with clinically N0 salivary gland carcinoma. METHODS One hundred nineteen patients underwent primary surgery and ipsilateral neck dissection for clinically N0 carcinomas of the major and minor salivary glands. Eighty patients (67%) had parotid tumors. Distribution of T class...
