Salivary gland tumours represent approximately 3% of all head and neck tumours. Warthin’s tumour, also known as Papillary cystadenoma lymphomatosum (PCL), is the second most frequent benign salivary gland neoplasm usually found in the superficial lobe of the parotid and is strongly associated with smokers. Here, we report a classical case of Warthin’s tumour of ten years duration in a 52year-ol...

composed of cells that exhibit sebaceous differentiation; these tumors account for less than 0.1% of all salivary gland neoplasms (1, 2). The parotid gland is the most frequently involved of the salivary glands, where sebaceous differentiation is common (3). There is little information available in English literature on the radiologic features of this rare neoplasm, especially that of cystic se...

The occurrence of a second malignant neoplasm (SMN) in patients who have been submitted to kidney transplantation is increasing and causes concern; parotid carcinoma is rarely reported after transplantation and may be related to long-term chemotherapy.Salivary gland carcinomas displaying exclusively myoepithelial differentiation-myoepithelial carcinomas (EMC) are rare, being less than 1% of all...

Superficial angiomyxoma (SA) is a rare benign cutaneous neoplasm first described by Allen et al in 1988. To the best of our knowledge, we report the first case of superficial angiomyxoma located in the parotid region. We also stress the importance of distinguishing this entity from other lesions that may be involved in this location such as cutaneous neoplasms, parotid tumours or cysts. We emph...

myoepithelioma is a rare neoplasm of the salivary glands, generally occurring in the parotid gland and less often in the minor accessory salivary glands of the oral cavity. it is known to be a rare entity occurring at unusual locations, which makes it difficult to diagnose. such a rare case of myoepithelioma in salivary glands present at an unusual location around the left orbit is presented here.

Myoepithelioma is a rare salivary gland neoplasm. They most commonly affect the major and minor salivary glands with the parotid gland being the most common, approximately 40%. Only 1% of all salivary gland neoplasms are myoepitheliomas. Myoepithelioma is usually a benign tumor arising from neoplastic myoepithelial or basket cells which are found between the basement membrane and the basal plas...

Acinic cell carcinoma (ACC) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of primary salivary gland malignancies. In the head and neck region, the parotid gland is the predominant site of origin and women are usually more frequently diagnosed than men. Previous radiation exposure and familial predisposition are some of the risk factors for ACC. A slowly enlarging...

Lymphoepithelial carcinoma of the salivary glands is a rare neoplasm that is characterized by a non-neoplastic lymphocytic infiltration associated with an epithelial proliferation. It involves mainly the parotid gland. Racial and geographical factors contribute to the pathogenesis of this tumor. We report a case of a 70-year old woman from a non-endemic area who presented with several months hi...

Benign lymphoepithelial parotid neoplasm with associated cervical adenopathy is a newly described head and neck manifestation of HIV infection, characterized previously as purely cystic masses on both CT and MR evaluations. The CT and MR findings in nine cases of surgically proved benign lymphoepithelial parotid lesions are presented. Five (56%) of the nine cases demonstrated masses that appear...
