Long lasting sialolithiasis can cause structural and functional changes of the salivary glands, inflammatory infiltration and fibrosis. However fat infiltration with sialolithiasis has not been described in the parotid glands. We describe a 60 years old man, bus-driver who presented with a history of reccurent right parotid sialadenitis and was diagnosed to have bilateral sialolithiasis and lef...

In this report, we describe a case of lipomatosis in the left parotid gland of an eight-year-old female Shetland sheepdog and review the relevant literature. Preoperative diagnosis of lipomatosis with Tru-Cut biopsy presented difficulties in this case. The postoperative diagnosis was based on the gross appearance of a non-infiltrative, circumscribed swollen mass in the parotid gland and the his...

Introduction: Solitary fibrous tumor is a rare, mesenchymal neoplasm that has been reported in numerous sites. Occurrence in the parotid gland is exceedingly rare.   Case Report: A 53-year-old man with a 2 cm solitary fibrous tumor of the left parotid gland, that was observed clinically and operatively and thought to be a neoplasm arising from Stensen's duct, is described. A pre-operative CT sc...

Although lipoma is commonly found in soft tissues, the parotid gland lipoma is among the rarest benign primaiy tumors of the major salivary glands. The unilateral swelling of the parotid gland is not an uncommon clinical problem, however, lipoma as a cause of parotid gland enlargement seldom comes in mind as differential diagnosis. We have discussed the clinic pathological features of parotid g...

The purpose of this study was to determine the incidence of an anterior extension of the parotid gland, such as an accessory parotid gland (APG) or facial process (FP) and to evaluate its characteristics on computed tomography (CT) scans. We reviewed CT scans of 1,600 parotid glands from 800 patients. An APG on CT was defined as a soft-tissue mass of the same density as the main parotid gland, ...

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...

HIV-salivary gland associated disease is a well accepted concept in the HIV-related literature. Parotid swellings, especially in its cystic benign lymphoepithelial form, have been largely reported. Oral mucoceles (ranulas) were also associated with HIV in some publications. The exact nature of this link between mucoceles and HIV is still to be clarified. The mainstream treatment of most of paro...

OBJECTIVES This study evaluates the interobserver variation in parotid gland delineation and its impact on intensity-modulated radiotherapy (IMRT) solutions. METHODS The CT volumetric data sets of 10 patients with oropharyngeal squamous cell carcinoma who had been treated with parotid-sparing IMRT were used. Four radiation oncologists and three radiologists delineated the parotid gland that h...

PURPOSE To examine the variation in the anatomy of parotid glands discerned by magnetic resonance imaging. METHODS Head and neck magnetic resonance scans of 16 patients (representing 32 glands) whose studies consisted of 5 mm contiguous sections were selected at random. The T1 weighted scans were thresholded and outlined to only encompass the parotid tissue. A volumetric analysis program (ISG...

SUMMARY The ability of foetal rat salivary epithelium, particularly from the parotid gland, to develop morphogenetically and functionally (amylase activity) in various mesenchymes, and the quantitative effects of altering mesenchymal mass on the development of the parotid epithelium, have been studied in vitro. Both parotid and submandibular epithelial rudiments were able to undergo morphogenes...
