BACKGROUND The most common histological diagnosis of bilateral parotid gland neoplasm is Warthin tumor. Bilateral malignant tumors of the parotid gland are extremely rare. METHODS A 60-year-old man presented with a painless mass in the right preauricular area and an MRI scan showed multiple masses in the parotid glands, bilaterally. A standard superficial parotidectomy was performed on the ri...

BACKGROUND Currently, clinical examination, ultrasound scanning (with or without fine needle aspiration cytology), preoperative CT-scan and MRI are available for the differential diagnosis of parotid gland swelling. A preliminary non-invasive salivary diagnostic tool may be helpful in the clinical decision making process. Altered salivary micro-RNA (miRNA) expression levels have been observed i...

Parotid gland oncocytoma is an uncommon, benign salivary neoplasm composed of mitochondria-rich oncocytes. The purpose of this study was to correlate MR imaging and histopathology of parotid gland oncocytomas and to define the features that may distinguish these neoplasms from other benign and malignant parotid gland tumors. The MR imaging features in 9 patients with a pathologic diagnosis of o...

Myoepithelioma is a rare benign neoplasm of major and minor salivary glands, composed almost exclusively of sheets, islands or cords of cells with myoepitheliomal differentiation. Myoepithelioma represents 1.5% of all salivary glands neoplasm, most commonly occurs in parotid gland. Here, we report a rare case of myoepithelioma of hard palate.

Canalicular adenoma is a rare benign salivary gland neoplasm affecting predominantly the minor gland. We present case of 55 year female who presented with mucosal nodule in left cheek and was diagnosed as based on morphology immunohistochemistry findings. Our that, it major – Parotid gland, 7 reported literature to best our knowledge.

Sialolipoma is a rare benign neoplasm and was recently described as a histological variant of intraoral lipoma. In the current report, the case of a of a 65-year-old female with a slow-growing mass in the right parotid gland with recurrence is presented. The initial clinical diagnosis was a benign salivary gland tumor. The tumor was situated between the right parotid gland and the right massete...

BACKGROUND Oncocytic carcinoma is an extremely rare neoplasm of the salivary glands. We report a case of oncocytic carcinoma arising in a parotid gland in a 66-year-old female. METHOD An excisional biopsy of the parotid tumor was performed. The specimen was submitted for histology and after fixation in formalin solution and inclusion in paraffin, 3-5 microm sections were stained with hematoxy...

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...

Salivary gland tumours are uncommon, representing less than 6% of head and neck neoplasm. Pleomorphic adenoma is the most common benign epithelial salivary gland neoplasm, comprising 50%-74% of all parotid tumours. It is followed by Warthin's tumour (4-14%). The authors retrospectively reviewed 282 eligible patients surgically treated for parotid gland tumours in the last 10 years, focusing on ...
