Salivary gland tumors constitute 3% of tumors in the body. Salivary gland tumors constitute 4% to 10.80% of all tumors in the head and neck tumors and most of them originate from the parotid gland. Most salivary gland tumors are benign. Basal cell adenocarcinoma is a rare salivary gland tumour. Most appear to be benign clinically. Metastases have occurred in less than 10% of patients. A 58-year...

Pleomorphic adenoma is the most common salivary gland tumor. also known as benign mixed Most commonly affected site parotid gland. It may occur in other major glands (submandibular and sublingual glands), lacrimal minor glands. arises a painless, firm swelling, slowly growing oral cavity. triphasic tumor that occurs epithelial, myoepithelial, chondromyxoid stroma. Complete surgical resection wi...

Swellings of the major salivary gland commonly lead to the differential diagnosis which includes benign and malignant tumors that are frequently associated with cystic degeneration or entirely cystic de novo. Only 6-9% of major salivary gland swellings are cystic lesions and 2-5 % are non-neoplastic in nature. This is a case report of such an asymptomatic unilateral parotid gland lesion in a 30...

Pleomorphic adenoma is mixed and usually benign tumor originating salivary glands. The most common salivary gland tumor is pleomorphic adenoma. The most common localization of pleomorphic adenoma is parotid gland. Although it is found in major salivary gland, pleomorphic adenoma may be found paranasal sinuses and nasal cavity rarely. A 74-year-old female presented with a 3-month history of ri...

Myoepithelial cells (MECs) are considered to be a key participant in most salivary gland diseases, particularly tumors. MECs structurally resemble both epithelial cells and smooth muscles. Diagnostic dilemmas caused are due to inadequacy of characterizing the wide spectrum of morphologic and immunologic features which are different for both normal and neoplastic MECs. This article discusses the...

Most salivary gland tumors are benign, malignant lesions accounting for 15-30% of the total. The most frequent site of salivary gland neoplasms is the parotid gland (80% of all cases). We present a case of malignant fibrohistiocytoma with atypical features due to its location (in the parotid region), size and rapid growth. Generally, this type of tumor arises in the lower limbs and in the abdom...

Pleomorphic adenoma is a benign salivary gland tumor that represents less than 5% of benign tumors in childhood. World literature suggests salivary gland tumors account for less than 3% of the head and neck tumors and benign Pleomorphic adenoma of minor salivary glands arising de novo is very rare. Here we report a case of Pleomorphic adenoma of minor salivary glands occurring on the palate of ...

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...

Salivary gland neoplasms are a heterogeneous and important group of tumors of the Oral and Maxillofacial Pathology. They comprise from 2 to 3% of all the salivary gland lesions and tumors1,2 because their heterogeneity, since several years, different classifications based in clinical or microscopic criteria had been appeared.3-7 The most recent and most widely used is that proposed by Seifert e...

Salivary gland tumors are a relatively rare and morphologically diverse group of lesions. Pleomorphic adenoma is a benign tumor of the salivary gland that consists of a combination of epithelial and mesenchymal elements. The tumor most commonly arises from the parotid (60-70%) or submandibular glands. It develops less frequently in a minor salivary gland, presenting as an intraoral mass depend ...
