Oncocytic carcinoma of the parotid gland is a rare neoplasm. To date 70 cases have been described in 55 reports. To the best of our knowledge the simultaneous occurrence of oncocytic carcinoma and second malignancy in another site (outside the parotid gland) has not been reported. An oncocytic carcinoma of the parotid gland is described in 56-year-old male with simultaneous breast cancer, empha...

The unusual case is described of a benign parotid gland neoplasm with intermingled sebaceous and lymphoid tissue, synchronous to breast cancer. In the past, the patient had undergone a simple surgical procedure for a cystic parotid gland lesion in that same gland. Secondary neoplasms have only occasionally been reported, since there are few cases for corroborating the strong correlation between...

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...

The parotid gland is the most common location of benign neoplasms affecting major salivary glands. Hybrid tumors are very rare tumor entities which are composed of two different tumor types, each of which conforms to an exactly defined tumor category. The tumor entities of a hybrid tumor are not separated but have an identical origin within the same topographical area. This report describes a 5...

Introduction: The parotid gland is the most common site for salivary gland tumors. 70-80% of salivary gland neoplasms occur in the parotid gland, of which 80% are benign, 20% are malignant of which 80% of the benign tumors are pleomorphic adenomas. Aims and Objectives: (1) To know the incidence of parotid gland tumors with respect to age and sex. (2) To study the various modes of clinical prese...

Deoxyribonucleic acid (DNA) was extracted from parotid gland tumors with phenol. The injection of this DNA into 24-hour to 1-week-old AKR mice resulted in a 65 per cent incidence of parotid tumors and/or epithelioid thymomas. Oncogenic properties of the DNA preparation were abolished by incubation with deoxyribonuclease. Cell-free filtrates of the parotid tumors inoculated into suckling AKR mic...

Salivary gland neoplasms account for 0.5-2% of all tumors worldwide, and can display a remarkable range of morphological diversity between different tumor types. The aim of this retrospective study was to present the clinico-pathologic characteristics of salivary gland neoplasms in a tertiary referral hospital in northwest region of Nigeria. Clinical and histopathological records of patients wi...

Chronic sclerosing sialadenitis (CSS) (Kuttner's tumor) is a benign fibroinflammatory condition most commonly affecting the submandibular gland. It presents as hard mass that mimics salivary gland neoplasms. We report an unusual presentation of Kuttner's tumor parotid in order to raise awareness this rare and underreported entity.

Tumors of the salivary glands constitute an important field of oral and maxillofacial pathology. The majority of salivary gland neoplasms are benign, with malignant salivary tumors accounting for 15 to 32 percent. The most common site for salivary gland tumors is the parotid gland, accounting up to 80 percent of all cases. This article reports the pathologic picture in a case of sebaceous adeno...

OBJECTIVE Assessment of benign and malignant lesions of the parotid gland, including metastatic lesions, is challenging with current imaging methods. Fluorine-18 FDG PET/CT is a noninvasive imaging modality that provides both anatomic and metabolic information. Semiquantitative data obtained from PET/CT, also known as PET/CT parameters, are maximum, mean, or peak standardized uptake values (SUV...
