Pleomorphic adenoma (PA), also known as mixed tumor, is the most common benign salivary gland neoplasm, characterized histologically by both epithelial and mesenchymal elements. Approximately 75% of PAs occur in the parotid gland, followed by the submandibular gland (15%) and minor glands of the palate and nasal septum (10%). Less common is the occurrence in the minor glands of the upper lip, c...

BACKGROUND Carcinosarcoma of the salivary glands is a rare neoplasm, and the minimally invasive form constitutes a subgroup with a more favorable prognosis. The cytomorphologic features of this neoplasm can be appreciated on fine-needle aspiration biopsy. METHODS AND RESULTS We present a patient with a minimally invasive carcinosarcoma ex non-recurrent pleomorphic adenoma (Ca ex PA) who under...

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...

BACKGROUND Warthin tumor is the second most common benign salivary gland neoplasm after pleomorphic adenoma. Warthin tumors occur almost exclusively in the parotid gland and periparotid lymph nodes, extraparotid localization is rare. METHODS AND RESULTS We describe a case of a patient presenting with a synchronous unilateral parotid gland and nasopharyngeal Warthin tumor. CONCLUSION We prop...

myoepithelioma is an uncommon benign neoplasm that most likely occurs in the parotid gland. extra-salivary myoepitheliomas are rare, with less than 10 cases reported in the sinonasal cavity. we present a rare case of benign myoepithelioma with recurrent behavior, abundant extensions to adjacent structures, and resistant to treat clinical course, which influenced the patient’s quality of life fo...

Adenoid cystic carcinoma (AdCC) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). About 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). Three clinically obvious characteristics of AdCC include slow growth rate, perineural invasion and high incidence of distant metastasis (1). The most commonly-affected sites of...

Myoepithelioma is a rare benign neoplasm of salivary glands. Accounts for less than 1% of all salivary gland neoplasms. It is more common in parotid glands foIIowed by small salivary glands. Myoepithelioma once was considered as extreme variant of pleomorphic adenoma. But now many authors consider the myoepithelioma as distinct pathological entity as it i of myoepithelial cells and behaves more...

65 The Chinese Journal of Dental Research Lymphoepithelial carcinoma (LEC) is an undifferentiated tumour that is associated with a dense lymphoid stroma. An exceptionally high incidence of this tumour is found in the Inuit populations and Asians1,2. This neoplasm has been associated with Epstein-Barr virus (EBV) infection2,3. LECs of salivary glands represent rare epithelial malignancies. They ...
