Oncocytomas of the salivary glands are rare benign epithelial tumors which occur most commonly in the parotid gland. The aim of our study was to characterize the clinical-radiologic-pathologic spectrum of parotid oncocytomas in a series of 10 cases seen in our institution between January 2003 and November 2008. The CT features of parotid oncocytomas in the largest imaging series of this rare bu...

BACKGROUND The purpose of this study was to evaluate our experience in the diagnostic approach to inflamed benign tumors of the parotid gland at a single tertiary center. METHODS A retrospective evaluation was carried out for all patients with signs of inflammation in the parotid gland on the ground of a benign parotid tumor, as confirmed by permanent histology. RESULTS Sixteen patients wer...

Acinic cell carcinoma of the salivary glands is a rare cancer representing a low grade malignancy. The recurrence of a tumor is sometimes encountered, usually within 5 years of initial operation. We describe an unusual recurrence after a long interval following primary surgery. In 1987, a 60-year-old woman underwent excision of a mass in the superficial lobe of the right parotid gland under the...

The major salivary glands consist of the parotid, the submandibular, and the sublingual glands. Under the control of the parasympathetic nervous system, the major salivary glands are responsible for the principal portion of saliva produced, which can be as much as 1.5 liters per day. The minor salivary glands of the oral cavity, pharynx, and upper airways contribute only a small percentage of t...

Hybrid carcinomas are rare neoplasms which are characterized by two different types of tumors localized in a single topographic region of the lesion. Parotid gland is the most common involvement site of hybrid carcinomas among salivary glands. The aggressiveness of the hybrid tumor depends on its high-grade component. In this article, we present a 71-year-old male case with the left parotid gla...

BACKGROUND AND PURPOSE The surgical approach to parotid tumors is different for benign and malignant neoplasms, but the clinical symptoms do not correlate well with histology. Difficulties in tumor classification also arise in imaging modalities, in which sonography has the lowest and MR imaging, the highest accuracy. The purpose of this study was to review our experience using conventional MR ...

BACKGROUND The purpose of this study was to identify the prevalence of sialoceles and the risk factors associated with their formation after parotidectomy. METHODS We performed a retrospective analysis of the data from consecutive patients who underwent partial superficial parotidectomy of parotid tumors. Demographic data, preoperative imaging results, operative variables, including tumor typ...

Pleomorphic adenoma or benign mixed tumor is the most common salivary gland tumor. It is most frequently located in the parotid gland, and is considered to be a benign neoplasm accounting for 70-80% of all benign tumors of the salivary glands [1]. Benign metastasizing pleomorphic adenoma is extremely rare, with only a handful of cases described. We report a case of a histologically benign mixed...
