Objective Fine-needle aspiration cytology is a valuable method for preoperative assessment of head and neck tumors. However, its accuracy in detection of salivary gland masses is controversial compared with other methods. The aim of this work was to evaluate the effectiveness and accuracy of fine-needle aspiration cytology (FNAC) in the diagnosis of parotid gland masses. Material and Methods ...
he pleomorphic adenoma otherwise called as benign mixed tumor, is the most common salivary neoplasm. 1 It accounts for 53% to 77% of parotid tumors, 44% to 68% of submandibular tumours and 33% to 43% of minor gland tumors. 2 Pleomorphic adenomas are derived from a mixture of ductal and myoepithelial elements. 2,3 The terms pleomorphic adenoma and mixed tumor both represent attempts to describe ...
The Warthin’s tumor or papillary cystadenoma lymphomatosum is a benign neoplasm which affects commonly the salivary glands und especially the parotid gland. We present a case of an 80-year-old Caucasian woman, who presented in our ENT department because of a progressive swelling in the left parotid gland. The clinical as well as the radiological findings suggested a multifocal lobular neoplasia...
Intraparotid hemangioma of the children is a rare neoplasm, posing diagnostic dilemma to the diagnosticians as well as treating clinicians. A 2-month-old male infant presented with a diffuse swelling in the parotid region since birth that was gradually increasing in size. The ultrasonography (USG) report was suggestive of a right intraparotid mass of uncertain etiology; whereas magnetic resonan...
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 is a rare malignant neoplasm of the salivary gland. Salivary gland neoplasms constitute 3% cancers all sites, which, 10–15% are malignant. Though adenoid most common tumor submandibular, sublingual and minor glands, it accounts for only 15% parotid cancers. They generally slow-growing spread relentlessly to adjacent structures. Hematogenous more than lymphatic spread, s...
OBJECTIVE The purpose of this study was to determine the diagnostic accuracy of using the retromandibular vein as seen on cross-sectional imaging to help differentiate superficial lobe from deep lobe tumors. METHODS Of the patients who had parotid neoplasms between January 1997 and July 2002, we were able to identify 44 patients with preoperative imaging studies that were available for evalua...
epithelial myoepithelial carcinoma is a rare biphasic low grade neoplasm of salivary glands; it most commonly occurs in the parotid gland but can also arise in minor salivary glands. here a case of 58-year-old female presented with left cheek swelling of one-year duration. ct scan revealed a localized submandibular salivary gland tumor mass not involving surrounding tissues. histological examin...
Parotid malignancy may occur as a primary neoplasm of the salivary tissue or as metastatic involvement of the parotid lymph nodes. Primary tumors of squamous cell carcinoma and malignant melanoma involving the skin of the head and neck have the potential to spread to lymph nodes of the parotid gland. Metastatic malignant melanoma to the back was exceptionally rare and no such reports have been ...
BACKGROUND AND PURPOSE Pleomorphic adenoma is the most common parotid neoplasm. It has a relatively high rate of recurrence after surgery. Imaging features of recurrent parotid pleomorphic adenoma have been infrequently reported in the radiology literature. In the present study, we reviewed our institutional experience with imaging of recurrent parotid pleomorphic adenomas. MATERIALS AND METH...
