Analysis of the Clinical Relevance of Histological Classification of Benign Epithelial Salivary Gland Tumours
ConclusionsA correct histopathological diagnosis of these tumours is necessary due to (1) preventing confusion with malignant salivary gland tumours; (2) only one (pleomorphic adenoma) has a considerable risk for malignant transformation, but all four histological types of basal cell adenoma can occasionally develop into malignancy, as does Warthin tumour; (3) sialadenoma papilliferum, oncocytoma, canalicular adenoma, myoepithelioma and Warthin tumour only occasionally recur; while (4) intraductal and inverted papilloma, lymphadenoma, sebaceous adenoma, cystadenoma , basal cell adenoma (apart from the membranous type) virtually never recur. No biomarker was found to be relevant for predicting recurrence or potential malignant development. Guidelines for appropriate treatment strategies are given.

ConclusionsThe present study determined the incidence rates of these rare tumors.
ConclusionsIn our retrospective cohort, the development of postoperative wound complications following parotidectomy did not appear to be significantly impacted by the use of a fibrin sealant.
CONCLUSION: Our study highlighted a variety of patterns and cell morphologies, on occasion within a single tumor, identical to breast disease. Histological and immunochemical examination revealed that anogenital mammary-like glands and HP share common features, which militates in favor of a common histogenesis.

AbstractWarthin ’s tumour was first adequately described in 1929 by an American pathologist, Aldred Scott Warthin. It is synonymous with papillary cystadenoma lymphomatosum (PCL), cystadenolymphoma or adenolymphoma. Giant salivary gland tumours are usually pleomorphic adenomas. The average size of Warthin’s tum our is reported to be about 2–4 cm. In the current fascinating case, an enormous disfiguring salivary gland tumour was reported which turned out to be Warthin’s tumour on histopathology, which is probably the largest PCL reported till date.
We describe the case of a 75-year-old woman with a supraglottic tumor that mimicked a mucoepidermoid carcinoma. The tumor was completely excised via a transcervical approach. Pathology identified it as a Warthin tumor. At follow-up, the patient maintained good oral intake. Computed tomography 3 months postoperatively confirmed complete tumor resection and detected no evidence of residual disease or recurrence. We also discuss our review of the literature on benign laryngeal salivary gland tumors, which included an analysis of 112 cases. The most common tumors were oncocytic cystadenomas (n = 65), pleomorphic adenomas (n = ...
Warthin tumours, also known as lymphomatous papillary cystadenomas, are benign, sharply demarcated tumours of the salivary gland. They are of lymphoid origin and most commonly arise from parotid gland tail.

AbstractThe salivary duct cyst (SDC) is a reactive ductal ectasia most frequently seen in major salivary glands, and likely caused by obstruction. The aim of this study is to define the clinical and histopathologic spectrum of intraoral SDCs. Cases were retrieved from the archives of Harvard School of Dental Medicine/StrataDx, Inc. from January 2012 to August 2014. There were 177 cases of which 103 (58.2%) occurred in females, with a median age of 56 (range 2 –95). Approximately half of cases (45.8%) presented in the area of the buccal mucosa, lower lip mucosa, or mandibular vestibule, and 23.2% presented in the floo...
Authors: Witt RL, Nicolai P Abstract The most important causes of recurrence of benign pleomorphic adenoma are enucleation with intraoperative spillage and incomplete tumor excision in association with characteristic histologic findings for the lesion (incomplete pseudocapsule and the presence of pseudopodia). Most recurrent pleomorphic adenomas (RPAs) are multinodular. MRI is the imaging method of choice for their assessment. Nerve integrity monitoring may reduce morbidity of RPA surgery. Although treatment of RPA must be individualized, total parotidectomy is generally recommended given the multicentricity of the...
Conclusion: The use of SOX10 may increase the diagnostic accuracy of oncocytic lesions on FNA. In this context, SOX10 is equivalent to DOG1 in ruling out benign lesions such as WT and ONC; however, negative results for SOX10 as well as DOG1 do not favor a benign diagnosis since MEC is often negative for both markers.Acta Cytologica
